The must-have Macro Loupe for all watch lovers

Founded in 1961 by Helmut Sinn, the German brand that bears his name specializes in technical watches for aviators and divers, placing engineering at the center of the product. This 856 UTC exemplifies this commitment:

- Its fully microblasted case is Tegiment-treated to ensure high scratch resistance.
- It features Ar dehumidification technology to reduce movement aging while monitoring the watch's water resistance (200m) via a small indicator on the side of the watch that turns blue in the event of a water resistance defect.
- Its movement (ETA 2893-2) is protected from magnetic fields up to 1000 Gauss.
- All this in a 40 mm diameter and only 11 mm thick.

A true tool watch, it accompanies me on all the adventures I don't dare take my other timepieces with me. Reliable and ultra-legible, the small UTC hand adds a touch of fun to this very "clinical" design. Delivered on a leather strap, I prefer it on a NATO strap to showcase its all-terrain appeal.

Technical expertise in the four corners of the world

An exact copy of the Breitling Navitimer reference 806, this re-edition takes all the characteristics of the original model by adding the latest know-how of the house through the manual manufacture caliber B09. An essential brand linked to aviation, Breitling has fascinated me since I was little. The beaded bezel of this Navitimer, its small diameter (41 mm) and its ultra-domed Plexiglas have finished convincing me!

Re-release of a legend!

Introduced in 1969, Zenith designed the Defy as a robust watch made for adventure with a water resistance of 300m and an octagonal case topped with a 14-sided bezel that earned it the nickname of a safe. This reissue limited to 250 pieces is powered by the Elite 670 caliber. The work done on the indexes is impressive and we find ourselves playing with the light to make them "flash". The 37mm diameter is ideal for me, sufficiently present on the wrist without falling into ostentation. All with an integrated bracelet three years before the arrival of the first icons designed by Gérald Genta... I love it!

The safe of time

Equipped with the latest version of the in-house movement (El Primero 3600, visible through the caseback), the Chronomaster Original takes up the aesthetic codes of the A386 reference from 1969. The historic colours of the sub-counters bring a certain balance to the dial and bring a touch of modernity. Designed for measuring short times, the sub-counter at 6 o'clock totals the minutes while the one at 3 o'clock displays the seconds and the central second hand the 1/10th of a second. The high frequency of the calibre (5 Hz) allows for exemplary fluidity of the small seconds located at 9 o'clock. The serenity and calm that emerge from the dial disappear the moment you push the chronograph pusher, leading the red hand into a mad race that questions our relationship with time and reminds us all of what it is possible to do in a limited moment. A legendary model and movement to rediscover in this modernised version!

Lightning!

Created in 1931, the Reverso was presented at the time as a sports watch that responded to the problem of robustness by offering a reversible case to protect the dial as desired. 
Nowadays, the Reverso belongs more to the category of dress watches, although by changing the strap (equipped with quick releases) it adapts to all outfits with disconcerting ease. 
The Art Deco style highlighted by the gadroons and the work done on the dial won me over: alternating vertically brushed surfaces and guilloché, flame-blued hands and small seconds at six o'clock. The most attentive will notice the railroad track which is here replaced by a fine guilloché going around the dial. One last detail that I love: the "1" which from afar seem to be only batons when they are not! 
The manual movement that equips this model is a real treat to wind and allows the watch to slip under all sleeves. One question remains: what should be written on the back of this icon?

Bill or face?

Founded in 1892 in Pennsylvania, Hamilton made a name for itself by supplying watches to the railways, thus synchronizing the hours on the network and significantly reducing accidents. Since the second half of the 20th century, the brand has worked closely with Hollywood. During the quartz crisis, the company joined the SSIH in 1974, which later became the Swatch Group (1998). 

Capturing the American spirit of the brand, the Spirit of Liberty is a call to freedom as evidenced by the words of Andrew Hamilton laser engraved on the bracelet "without liberty life is a misery". Acquired a few years ago when I was looking for my first automatic watch, its sunray dial, transparent back and dressy style seduced me. It is this model that definitively made me switch to the wonderful world of mechanical watches!

My first mechanical watch!

The Sinn brand was created in 1961 by the visionary pilot and watchmaker Helmut Sinn in Frankfurt, Germany. Helmut Sinn was a World War II fighter pilot and survived several plane crashes. He used this experience to design shock and vibration resistant watches for German Air Force pilots and soldiers.&nbsp;
Additionally, the Sinn brand was the first to use helium for commercial diving watches, providing greater safety for professional divers. The Sinn brand is also known for working with NASA to develop watches for use in space. The range includes models like the <a href="https://www.dialicious.com/en/sinn/556">Sinn 556</a>, the <a href="https://www.dialicious.com/en/sinn/ezm_3">Sinn EZM 3</a>, the <a href="https://www.dialicious.com/en/sinn/u1">Sinn U1</a>, the <a href="https://www.dialicious.com/en/sinn/103_st">Sinn 103 ST</a>, the <a href="https://www.dialicious.com/en/sinn/104_st">Sinn 104 ST</a> and the <a href="https://www.dialicious.com/en/sinn/u50">Sinn U50</a>.
<h2 dir="ltr">How much does a Sinn watch cost?</h2>
Prices of new Sinn watches evolve regularly and differ depending on the model. Most cost between &euro; 1,500 and &euro; 3,000 depending on the finishes. Price differences can be significant between the brand's different collections. For example, the price of a <a href="https://www.dialicious.com/en/sinn/556">Sinn 556</a> fluctuates between &euro; 1,325 &euro; and &euro; 1,474 and the <a href="https://www.dialicious.com/en/sinn/356">Sinn 365 chronographs</a> oscillate between &euro; 2,390 and &euro; 2,865.

(Updated April 2024)

For a little less than two years, I've been searching for THE watch that would best accompany me in my daily life. As a sound technician, I need it to be break-resistant, scratch-resistant, and have excellent readability, day and night. I needed a date display and precision... This 856 ticks all these boxes and more...
I also had the goal of trying to collect a single watch, and if I had to keep only one, it would undoubtedly be this Sinn!!

My best everyday tool watch

I am definitely a fan of tool watches.
First aviator watch in my collection, I am really not disappointed, wearing comfort 40mm for a thickness of 11mm, readability, technicality, everything is combined in this watch.
The versatility on different bracelets makes it versatile in my eyes.

The brand Serica was created in 2019 by J&eacute;r&ocirc;me Burget and 3 friends in Paris, France. The name Serica comes from a lost region at the end of the Far East that the Greeks and Romans named it like this. This place echoes the genesis of the brand, which aims to design quality mechanical watches in a neo-retro style, ready to follow you to the ends of the world.
The range includes watches such as the&nbsp;<a href="https://www.dialicious.com/en/serica/4512">Serica 4512</a>, the&nbsp;<a href="https://www.dialicious.com/en/serica/5303">Serica 5303</a> and the&nbsp;<a href="https://www.dialicious.com/en/serica/8315">Serica 8315</a>. One of the particularities of this brand is that its name does not appear anywhere on the dial, in order to encourage the enthusiast to buy a design, finishes and proportions, and not just a name. In July 2023, Serica launched the Serica 5303 COSC, a chronometer version certified by the Swiss Official Chronometer Testing Institute.
The&nbsp;<a href="https://www.dialicious.com/en/serica/6190">Serica 6190</a> surfing on the bases of the brand's first reference, the Serica 4512. This 6190 follows the stylistic codes of the brand, lyre lugs, a choice of different dials and the possibility of choosing the position of the crown at 3 o'clock or at &ldquo;Destro&rdquo; mode at 9 o&rsquo;clock. This Serica 6190 is powered with the Soprod M100 caliber COSC (Official Swiss Chronometer Certification) certified, like the current productions of the other 5303 and 8315 models.&nbsp;
Since November 21, 2024, Serica has been offering a very daring new collection... A dress watch off the beaten track called &ldquo;Parade&rdquo; under the reference 1174. These 4 figures, like all other Serica references, offer a symbolism derived from the golden number or divine proportions whose ratio between length and width is 1.174... A novelty offered for pre-order at &euro; 1,490 for one delivery planned for March 2025...
