Maurice Lacroix Miros: owner reviews and feedback

The Maurice Lacroix Miros, whose earliest reliable public records found date back to 1982, is a collection that occupied an important position in the Swiss brand’s range for several decades. The exact year of its original creation is not communicated, as the available documentation from 1982 already refers to a new model belonging to the Miros collection. At that time, the range notably included elegant rectangular stainless-steel watches before gradually expanding to round models, quartz watches, automatics, chronographs, Coussin versions and even divers.

The Miros therefore does not correspond to one single design but rather to a family that evolved with the tastes and uses of the 1980s, 1990s and 2000s. It nevertheless retains several constants: carefully designed yet relatively understated cases, frequent use of sapphire crystal, particular attention to bracelets and a desire to combine Swiss elegance with everyday ease of use. The latest documented generations adopt more contemporary diameters of 39 to 41 mm and can offer water resistance of up to 300 metres.

Design & legibility: a collection with many faces

Discussing the design of the Miros requires distinguishing between several periods. The earliest documented watches notably use slim rectangular cases, white dials with Roman numerals and metal bracelets with slightly rounded links. By the end of the 1990s, the family expanded into sportier round watches and, in 1999, Maurice Lacroix presented a Miros chronograph characterised by a black dial, metallic hour circle and three counters arranged in a balanced manner. Later generations often simplify the dial around large applied markers, Arabic numerals at 6, 9 and 12 o’clock and a date window at 3 o’clock. Some variants add sunbrushed surfaces, guilloché-style patterns, diamonds or stronger colours. The Miros is defined less by one precise shape than by a constant search for balance between classical elegance and sporty presence. Diver versions logically adopt larger luminous hands and hour markers together with a rotating bezel, while Coussin models use a case with rounded corners. This diversity explains why two Miros watches can look very different while belonging to the same family. For a pre-owned buyer, identifying the exact reference is therefore far more useful than relying on the Miros name alone.

Case, bracelet and comfort: widely varying proportions

Dimensions are one of the principal differences between generations of Miros. Older rectangular references could use widths of around 22 to 25 mm, while men’s round watches from the late 1990s and early 2000s often measure approximately 35 to 40 mm. The modern Miros Date consequently reaches 40 mm, the chronograph approximately 39 or 40 mm depending on generation, the Coussin Réveil approximately 37.5 x 39.6 mm and the Divers around 41 mm. Cases are predominantly made from stainless steel and paired with sapphire crystal on the more recent references. Depending on the version, water resistance varies considerably: 50 metres on certain dress or Coussin watches, 100 metres on Miros Date and Chronograph models, 200 metres on the automatic Diver and up to 300 metres on the Diver Chronograph. This wide range of dimensions and water resistance shows that a Miros should be chosen according to its reference rather than the collection name alone. Metal bracelets play an important role and generally use a folding clasp, but Maurice Lacroix also offered leather on dressier models and some Coussin versions. Older examples now require particular attention to bracelet condition, the number of available links and the water resistance actually retained.

Movement: Swiss quartz, automatic and practical complications

The Miros also illustrates the mechanical diversity of Maurice Lacroix before the brand concentrated more of its communication on its own calibres and collections such as Masterpiece, Pontos and later Aikon. A large proportion of Miros watches rely on Swiss quartz movements, particularly well suited to the Date and Chronograph models. Certain older references use ETA calibres, while more recent chronographs notably employ an architecture such as the Ronda 5040.B. Automatic watches nevertheless represent an important part of the family, particularly certain classic Miros models and the Divers. The Miros Diver MI6028 is documented with the Maurice Lacroix ML115 calibre, based on a Swiss automatic architecture of the Sellita SW200 type, with automatic winding, central seconds and date. The principal advantage of the Miros today lies in its use of relatively conventional movements that are generally familiar to specialist watchmakers. This can make servicing easier for a watch that is no longer part of the current catalogue. Quartz models mainly require attention to battery condition and avoiding leaving an exhausted battery inside the watch for too long. For automatics, servicing should be considered according to the actual mechanical condition rather than an arbitrary interval. On an older Diver, a water-resistance test is essential before immersion even if the caseback still states 200 or 300 metres.

Chronological milestones and main models (1982–2025)

(2000) Maurice Lacroix Miros Lady Silver Date:

This compact Miros illustrates the transition between the classical watches of the 1990s and the more structured collections that followed. The Maurice Lacroix Miros 59749 is a women’s quartz watch offered at approximately 24 to 25 mm depending on the documented example. It combines a stainless-steel case with a metal bracelet and was notably available in two-tone configurations. The silver dial uses a straightforward layout intended to remain easily readable despite its small diameter. Preserved examples use an ETA 901.001 quartz movement, a compact Swiss architecture designed for smaller watches. The crystal encountered on documented pieces can be mineral glass, which requires greater care against scratches than sapphire. Today, the watch should primarily be regarded as a dressy vintage piece. Its age makes it particularly important to check the condition of the bracelet, battery and seals before relying on it for everyday use.

(2000) Maurice Lacroix Miros Date Silver:

The Miros Date of this period takes a much more traditional approach to the everyday men’s watch. The Maurice Lacroix Miros 69743 has a stainless-steel case measuring approximately 35 to 36 mm, a size that now feels relatively compact but perfectly reflects the classical proportions of the late 1990s. Several configurations are documented with silver, white or black dials together with full stainless-steel or two-tone steel and gold-tone bracelets. It uses a Swiss quartz movement with hours, minutes, central seconds and date. Sapphire crystal is a genuine advantage for a watch intended for regular use, while original water resistance is stated at 100 metres in certain documentation. The design remains comparatively understated, with easily identifiable markers or numerals and a fixed bezel. For a modern wrist accustomed to watches of 40 mm or more, this reference provides a significantly more discreet experience and can also suit a wide range of wearers.

(2005) Maurice Lacroix Miros Coussin Réveil Silver:

The Coussin Réveil represents one of the most original variations in the family. The Maurice Lacroix Miros Coussin Réveil MI5027-SS001-110 uses a stainless-steel cushion-shaped case measuring approximately 37.5 x 39.6 mm, with rounded corners and a presence very different from traditional round or rectangular Miros watches. Its silver dial features black Roman numerals, a date display at 6 o’clock, small seconds at 3 o’clock and an indication associated with the alarm function around 9 o’clock. The movement is quartz, a logical choice for managing the alarm while maintaining straightforward operation. The crystal is sapphire and stated water resistance reaches 50 metres. A black leather strap reinforces its dressy character and its folding clasp provides more secure fastening than a conventional pin buckle. This reference is particularly interesting for enthusiasts looking for a Miros that differs from simple three-hand models and who appreciate a complication that can genuinely be useful in everyday life.

(2009) Maurice Lacroix Miros Date Silver:

By the end of the 2000s, the Miros adopted more contemporary proportions while retaining a very straightforward presentation. The Maurice Lacroix Miros MI1067 is documented with a stainless-steel case measuring approximately 39 mm in diameter and only 7.5 mm thick, giving it an especially slim profile for an everyday watch water-resistant to 100 metres. The crystal is sapphire and the watch uses a steel bracelet visually integrated with the case. The silver dial prioritises clarity with luminous hands, central seconds and a date window. The movement is Swiss quartz, consistent with the low thickness and objective of simple operation. A screw-down crown is specified in surviving commercial documentation. This combination of slimness, water resistance and metal bracelet makes the MI1067 suitable for the office as well as general daily activities, provided an older example has had its seals checked before significant exposure to water.

(2010) Maurice Lacroix Miros Diver Automatic Green:

The automatic Diver represents one of the sportiest Miros watches and one of the most sought-after versions on today’s pre-owned market. The Maurice Lacroix Miros Diver Automatic MI6028-SS062-330 uses a stainless-steel case measuring approximately 41 mm and 11.5 to 12 mm thick, which remains reasonable for a mechanical dive watch. Its black dial is paired with a unidirectional rotating bezel in dark green tones and small green accents on the dial and seconds hand. Applied markers and hands receive luminous material and the date appears at 3 o’clock. The crystal is sapphire, the crown screws down and stated water resistance reaches 200 metres. The automatic ML115 movement drives hours, minutes, seconds and date. The metal bracelet ends in a safety folding clasp. Several bezel and dial colours existed, together with Chronometer editions limited to 999 pieces, making verification of the complete reference essential when considering a purchase.

(2012) Maurice Lacroix Miros Date Silver 40 mm:

This generation particularly well summarises the “less is more” philosophy used by Maurice Lacroix to reposition the Miros in the early 2010s. The Maurice Lacroix Miros Date MI1018-SS002-130 receives a round stainless-steel case measuring 40 mm and approximately 8.4 mm thick, a sapphire crystal and a metal bracelet closed by a folding clasp. The silver sunbrushed dial is enlivened by slim markers together with Arabic numerals at 6, 9 and 12 o’clock. The date appears at 3 o’clock and the hands together with certain markers receive luminous treatment. The watch uses a Swiss quartz movement and remains water-resistant to 100 metres. This combination of limited thickness and a 40 mm diameter allows it to slip easily beneath a sleeve without giving the very small appearance of some earlier Miros models. Several variations existed with black or silver dials, steel, rose-gold-coloured plating and two-tone bracelets.

(2012) Maurice Lacroix Miros Date Lady Black Diamonds:

The women’s collection applies the simplicity of the Miros Date while adding significantly more decorative options. The Maurice Lacroix Miros Date Lady MI1014-SD502-330 uses a 32 mm stainless-steel case paired with a Swiss quartz movement and black dial. This family was offered with different combinations of steel, black treatment, rose-gold-coloured plating and diamonds. On diamond-set versions, the bezel can carry up to 60 diamonds with a stated total weight of approximately 0.45 carat, while certain variants also add diamonds to the dial. The crystal is sapphire with internal anti-reflective treatment and stated water resistance reaches 100 metres. The date window remains positioned at 3 o’clock and the hour and minute hands are luminous. The three-row metal bracelet uses a push-button folding clasp. Despite the precious elements, the 32 mm diameter and straightforward dial layout preserve a relatively discreet character for everyday wear.

(2013) Maurice Lacroix Miros Sport Chronograph Black:

The Miros chronograph of this generation adopts a sportier expression than the Date while remaining comparatively restrained in size. The Maurice Lacroix Miros Chronograph MI1098-SS042-330 has a stainless-steel case measuring approximately 40 mm, sapphire crystal and stated water resistance of 100 metres. The black dial accommodates several counters, a date window and a tachymeter scale, producing a significantly busier presentation than the Miros Date. The Swiss Ronda 5040.B quartz movement is documented for this reference and allows chronograph functions to be offered without excessively increasing thickness or requiring the servicing associated with a mechanical chronograph. The stainless-steel bracelet reinforces the versatile character of the watch, although some variations were also offered on darker straps. For daily use, quartz means that the chronograph function remains immediately available even when the watch has spent several days in a drawer. This reference therefore particularly suits someone who appreciates the Miros but wants more information and visual presence on the dial.

(2013) Maurice Lacroix Miros Diver Chronograph Brown:

The Diver Chronograph pushes the sporting philosophy of the Miros considerably further than the classic Date versions. The Maurice Lacroix Miros Diver Chronograph MI1108-SS072-730 uses a stainless-steel case measuring approximately 41 mm, a metal bracelet, screw-down crown and sapphire crystal. Its brown or bronze-coloured dial is paired with a matching bezel, luminous hands and markers and a date aperture positioned around 4 o’clock. The movement is Swiss quartz with a chronograph function, and the functions include hours, minutes, seconds, measurement of short elapsed times and date. Stated water resistance reaches 300 metres, higher than the 200 metres of the automatic MI6028 Diver and the 100 metres of Miros Date models. This makes it one of the references best suited to aquatic use in the more recent history of the collection, naturally subject to a water-resistance test on an older example. Its combination of a brown dial and dive-watch construction also gives it an unusual personality among Swiss sports watches of its period.

Choosing the right version: size, variants, bracelets and use

The first step is to identify precisely what type of Miros is being considered. A 25 mm rectangular reference, a round 40 mm Date and a 41 mm Diver provide completely different experiences on the wrist. For versatile use, Miros Date models measuring between 35 and 40 mm are generally the easiest to integrate into everyday clothing. Smaller diameters particularly suit those who appreciate a discreet vintage aesthetic, while versions around 40 mm provide a more contemporary presence.

For a watch intended for office wear or to sit beneath a sleeve, thickness deserves as much attention as diameter. The approximately 7.5 mm MI1067 or approximately 8.4 mm MI1018 remain relatively slim. Divers and certain Coussin models are naturally thicker. A slim Miros on a steel bracelet can easily serve as a sporty dress watch, whereas a Diver with a rotating bezel immediately appears more technical. Trying the watch on remains preferable when rectangular or cushion-shaped dimensions make nominal width difficult to interpret.

The choice between quartz and automatic essentially depends on the relationship desired with the watch. Quartz is perfectly suited to a Miros worn occasionally: it continues running when left unworn for several days and mainly requires periodic battery replacement. An automatic Miros provides more mechanical character but requires greater attention when rotated with several other watches. On a pre-owned piece, servicing history often matters more than the type of movement itself.

Particular attention should be given to original metal bracelets. Several Miros watches have bracelets whose design flows directly into the case, and finding additional links many years later can be difficult. Before purchase, it is therefore important to check that the bracelet is long enough for the wrist and that the clasp operates correctly. On models with conventional lug spacing, a leather strap can provide a simple way to refresh the appearance and reduce the weight of the watch.

Finally, original water-resistance ratings should never be interpreted as a permanent guarantee on a watch that is fifteen, twenty or forty years old. A Miros Diver rated to 200 or 300 metres when new may now have hardened seals or a crown that no longer provides the same protection. A water-resistance test before swimming is therefore essential for an older Miros. For a watch intended only for office wear or a collection rotation, the condition of the dial, crystal, bracelet and movement may instead deserve greater priority. Other customers’ opinions are essential.

Conclusion

The Maurice Lacroix Miros is less a single watch than an entire chapter in the history of the brand. Across several decades, it existed as rectangular dress watches, three-hand date models, chronographs, Coussin watches and genuine automatic or quartz divers. This diversity means that the precise reference, diameter, movement and water resistance should be examined before comparing two examples. Miros Date watches are particularly well suited to discreet everyday use, while Coussin models offer greater originality and Divers appeal to those looking for a sportier presence. On the pre-owned market, condition, servicing history and bracelet completeness have now become as important as the original specifications.
