The Heritage

The Omega Constellation Quadra Quartz 28 Chronograph (ref. 1841.70.34) features a 28mm stainless steel case with integrated lugs and mother-of-pearl dial. This dress watch embodies Swiss precision since 1952, with refined proportions and an integrated bracelet. Milano Straps offers bespoke alligator leather strap customization through Atelier Casati Milano, hand-fitted to the iconic Constellation architecture for aesthetic continuity.
Made to Measure

The strap for this watch is made to measure

On the Omega Constellation the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

FAQ

Can you fit a standard strap on this Omega Constellation?

No. The bracelet is integrated directly into the case — the attachment is not a standard industrial lug where you can simply insert any strap. If you want to replace the bracelet with a leather strap, you need an artisan who works bespoke, directly on the case. That's what I do in the atelier.

How does the bespoke strap work for the Constellation 1841.70.34?

Bring the watch to <a href="/pages/casati-booking">Atelier Casati Milano</a> — by appointment only. I take measurements directly from the case, study the interface with the lugs, and build the strap so it attaches perfectly and continues the watch's design. Every terminal is hand-modelled to respect the proportions.

Which leather would you recommend for such an elegant, perfectly proportioned watch?

Alligator Mississippi. It has that squared structure, that solidity which speaks the same language as the Constellation — a watch that doesn't shout, that possesses a rare restraint. The leather ages beautifully, remains stable over the years, and the colour deepens without transforming. For someone wearing it every day, it's the most honest choice.

How long does a well-made strap last?

It depends on how you use it. With proper storage and a bit of care — a dry environment, no chlorine, no prolonged water exposure — it easily lasts ten, fifteen years. The leather ages, develops a patina, changes tone. It's not decay: it's character that builds itself. Anyone who understands craftsmanship recognises this language.

Is the Constellation 1841.70.34 truly a historic watch?

Yes, but not as a frozen artefact of the past. Born in 1952 as an instrument of chronometric precision, the Constellation embodied for decades the balance between technique and sober proportions. This 28mm reference maintains that philosophy — a watch you'll wear well even twenty years from now.
