The Constellation 1312.10.00, seen from the bench

The Omega Constellation 1312.10.00 is built around the Omega 1532 manual caliber and features a 33.50mm two-tone case combining yellow gold and stainless steel with signature decorative lugs. The model has a 16mm lug width, making it compatible with standard aftermarket straps. Launched in the 1950s as an evolution of the 1952 original, this versatile timepiece balances formal elegance with reliability, housed in a bicolor case that requires skilled construction to maintain harmonious proportions.

Frequently asked questions

What lug width does the Omega Constellation 1312.10.00 have?

The Omega Constellation 1312.10.00 features a lug width of 16mm. This width is the standard construction specification for the model and is essential to ensure compatibility with any aftermarket strap. The measurement should be taken on the inner part of the lug using a digital caliper or by consulting an expert.

Which strap is best suited for the bicolor Constellation 1312.10.00?

Cognac or dark brown alligator is the most elegant solution for the 1312.10.00. Its natural grain and regular texture convey exclusivity and create a sophisticated tonal dialogue with the yellow gold and steel case. Black calf leather and vegetable-tanned leather are also excellent choices, depending on the context of use.

How do you change the strap on the Omega Constellation 1312.10.00?

Changing the strap requires a specific tool: a spring bar tool. Position the tool under the spring lever of the lug, apply gentle pressure to release it from the hole, then extract the bar. Repeat the operation on the other side. Insert the new strap by aligning the lateral holes and reinsert the bar. If you prefer a professional experience, the Casati Milano atelier offers strap-change service by appointment.

Is the strap of my Constellation 1312.10.00 compatible with other Omega models?

No. Since the 1312.10.00 features a 16mm lug width, the strap is compatible only with other Omega models (or other brands) that use the same width. Before purchasing an aftermarket strap, always verify the lug width of your watch. On milanostraps.it you will find a wide selection of 16mm straps specifically compatible with this model.

How long does a leather strap last on the Constellation 1312.10.00?

The lifespan of a leather strap depends on materials, usage, and maintenance. A high-quality alligator or calf strap with vegetable tanning can last 3-5 years under normal conditions; rubber or NATO straps have similar durability. The Casati Milano atelier offers an 18-month warranty on all custom straps, guaranteeing construction quality and repairs.
