The Constellation 123.20.27.60.57.001 (aka: 12320276057001), seen from the bench

The Constellation Quartz 27, launched in 1952, features a champagne mother-of-pearl dial and brushed stainless steel case with yellow gold. This 27mm model showcases the iconic Manhattan integrated bracelet with signature griffe detailing at 3 and 9 o'clock, representing sophisticated elegance from Swiss watchmaking's golden era.

Frequently asked questions

Can you fit a standard strap to the Omega Constellation 123.20.27.60.57.001?

No, the bracelet is integrated into the case. The lug attachment is proprietary and a standard strap won't fit. But in the atelier I craft the strap bespoke directly on your watch, hand-modelling the attachments to your case.

How does the bespoke strap service work for this model?

We work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>, Via XX Settembre 15 in Milan. I take measurements directly from your case, study the geometry of the griffes, and build the strap that integrates perfectly with the watch.

Which leather do you recommend for the Constellation?

I prefer Swift serico for this model: it keeps the contemporary elegance of the yellow gold and steel case alive without weighing it down. If you want something richer and more precious, Mississippi Alligator holds up beautifully to the sophisticated character of this timepiece.

How long does a well-made strap last?

A strap built with reserve leathers lasts years with care. The leather ages well: it patinas naturally and becomes softer. I recommend avoiding direct heat sources and cleaning the strap with a slightly damp cloth now and then.

Why does the Constellation have that design with the griffes?

Launched in 1952, the Constellation carries the griffes at 3 and 9 o'clock as Omega's visual signature. That geometry frames the case and gives it architectural weight. On a 27mm model like the 123.20.27.60.57.001, crafting a strap that dialogues with that shape is the real work: every millimetre counts.

The next step

The right strap isn't chosen. It is built, together.
