Frequently asked questions

What is the lug width of the Omega Constellation 1212.10.00?

The Constellation 1212.10.00 has a lug width of 16mm. This width is standard for small case watches (33.50mm) and is compatible with all 16mm straps available on the market. To verify, use a digital caliper measuring between the inner edges of the lugs.

What is the best strap for the Constellation 1212.10.00?

The best strap depends on usage: for formal occasions we recommend cognac or burgundy alligator which enhances the yellow gold. For elegant daily wear, vegetable-tanned calf leather offers natural patina over time. For sporty-casual contexts, a navy blue or grey NATO strap maintains balanced proportions. The Casati Milano atelier can create bespoke shell cordovan solutions for those seeking chromatic evolution.

How do you change the strap on the Constellation 1212.10.00?

The Constellation 1212.10.00 uses standard 16mm spring bars. Obtain a spring bar tool (or request assistance from a watchmaker), gently extract the pins from the old lugs, insert the new strap by aligning the pins into the attachments, and verify it is securely fastened. The operation is straightforward and does not require specialists for those with experience.

Which aftermarket straps are compatible with the Constellation 1212.10.00?

All straps with 16mm lug width are compatible with the 1212.10.00. You can choose from leather (alligator, calf, shell cordovan, nubuck), fabric (NATO, woven straps) or rubber. Milano Straps offers a selection of customizable 16mm straps ready for shipment, from classic to contemporary designs.

How long does a leather strap last on the Constellation 1212.10.00?

A quality leather strap (alligator, vegetable-tanned calf, shell cordovan) lasts on average 3-5 years with daily use, up to 7-8 years with occasional wear. Durability depends on humidity, sun exposure and frequency of wear. Casati Milano straps include an 18-month warranty and can be restored or replaced if necessary.
