Serica 7505 Enamel Black - Specifications, Prices and Owners' Reviews

Serica 7505 Enamel Black offers a compact, sharp and highly coherent interpretation of the field watch according to Serica. With this new 7505 Field Chronometer reference, the French brand continues its exploration of utilitarian watchmaking with a strong design identity by introducing a format that is smaller than the Ref. 6190 without giving up the tool-watch spirit that defines the collection. Presented as a watch that is smaller and thinner yet just as capable, the 7505 retains real professional vocation in a format better suited to smaller wrists and to those looking for a more compact daily presence. In its Black Minute Critical Dial version, it focuses on a more direct, more functional and more radically instrumental reading. 

What makes this reference especially appealing is its ability to remain deeply Serica while introducing real aesthetic renewal. The 7505 is not presented as a simple downsized 6190, but as a genuinely new watch with a redesigned case, curved inner lugs, polished sides, alternating finishes and half-spheres on the bezel extending the dial’s cardinal markers. In the black version, the Minute Critical Dial pushes the watch toward a more strictly functional register than the dressier Serica 7505 Tuxedo. 

What are the characteristics of the Serica 7505 Enamel Black?

Case of the Serica 7505 Enamel Black

The case of the Serica 7505 Black is made of stainless steel and uses an especially compact format. With its 35 mm diameter, 41.5 mm lug-to-lug length and 9.6 mm thickness including the crystal, this watch belongs to a category of field watches that prioritises efficiency, sobriety and comfort over any show of force. Serica insists that the 7505 is smaller and thinner than the 6190 while remaining just as capable. This new case introduces curved inner lugs, the absence of chamfers, polished sides and half-spheres on the bezel that visually extend the dial’s cardinal markers. The watch also maintains a 20 ATM water resistance rating, confirming its utilitarian and robust purpose. 

Black Minute Critical dial and visual identity

The black Minute Critical dial is the central element of this version of the Serica 7505. The PDF explains that this new display places more emphasis on immediate and forceful reading of the full 60-minute scale. Unlike the TXD, which is more graphic and dressy, this black version pushes the watch toward a more strictly functional register. The painted luminous markers, broad-arrow hands and highly direct layout all reinforce that sense of pure instrumentality. 

Movement and performance

The Serica 7505 Enamel Black is powered by the COSC-certified SoProd M100 calibre. It is a Swiss self-winding mechanical movement beating at 28,800 vibrations per hour (4 Hz) and fitted with 25 jewels. The announced power reserve is 42 hours, together with a decorated plate featuring Côtes de Genève. The choice of a chronometer-certified movement strongly reinforces the coherence of the watch: despite its compact format, the 7505 Black stands on a serious and precise mechanical base. 

Bracelet and comfort

The Serica 7505 Black is fitted with a redesigned Bonklip bracelet, a signature element of the brand’s language. For this new reference, Serica introduces curved end-pieces, polished squared links, a stronger taper and above all a new Safe-Lock® clasp. This clasp was designed to provide more security while still allowing the bracelet to be worn slightly loose. Available in three sizes - small, regular and extra long - the bracelet plays a full part in the character of the watch and its comfort on the wrist. 

Wearability and everyday use

The great strength of the Serica 7505 Black lies in its ability to deliver a real tool watch in an especially wearable format. Its 35 mm size, restrained thickness and Bonklip bracelet make it a very easy watch to live with, including on modest wrists. Yet this compactness comes with no major compromise: COSC certification, 20 ATM water resistance, double-domed sapphire crystal and overall robustness all remind us that this is very much a professional-minded watch. 

Serica 7505 Enamel Black: a compact, precise and resolutely utilitarian field watch

With the 7505 Black, Serica offers a watch that intelligently renews its language without betraying it. The compact 35 mm case, black Minute Critical enamel dial, COSC-certified SoProd M100 movement and Bonklip bracelet equipped with the new Safe-Lock form a highly coherent whole. This reference does not try to impress through size or through a multiplication of functions. Instead, it appeals through density of proposition: a real tool watch, precise, wearable and visually distinctive. 

Conclusion

The Serica 7505 Enamel Black is aimed at enthusiasts looking for a field watch French in spirit, compact, precise and endowed with real utilitarian purpose. Thanks to its black Minute Critical dial, COSC-certified movement, 35 mm case and redesigned Bonklip bracelet, it offers a particularly convincing reading of the contemporary tool watch in a restrained format.

Dialicious owner reviews are a relevant way to choose the watch that truly suits you.
