Frequently asked questions

What is the lug width of the Omega Constellation 1201.10.00?

The lug width of the Omega Constellation 1201.10.00 is 14mm. This measurement represents the horizontal distance between the two lugs where the strap or bracelet attaches. It is essential to verify this dimension before purchasing an aftermarket strap to ensure perfect compatibility and avoid stress that could damage both the watch and the strap.

What is the best strap for the Omega Constellation 1201.10.00?

The best strap depends on intended use and personal aesthetic preference. For formal settings, a black or dark brown alligator in vegetable tannage offers elegance without compromise. For daily wear, a burgundy shell cordovan combines exceptional durability and patina that improves over time. For water sports or extreme practicality, a NATO or structured rubber maintains visual balance while keeping maintenance to a minimum.

How do you change the strap on the Omega Constellation 1201.10.00?

Changing the strap requires a specific tool called a spring bar removal tool. Gently position the forked end under one of the lateral pins, apply upward pressure to disengage it from its seat, and repeat for the other side. Insert the new strap ensuring that the pins lodge correctly in the new lugs. This process is generally painless if executed calmly and precisely. If you prefer to avoid the risk, the Casati Milano atelier offers mounting service by appointment.

Is an aftermarket strap compatible with the 1201.10.00?

Yes, any strap with a 14mm lug width is technically compatible with the Omega Constellation 1201.10.00. However, for optimal results, it is important that the strap is made by artisans specialized in luxury watches, respecting the construction margins of the original watch. Milano Straps are specifically crafted for this class of watches, guaranteeing construction according to haute horlogerie standards and finishes that enhance the aesthetic identity of the Constellation.

How long does a leather strap last on a watch like the Constellation 1201.10.00?

The lifespan of a leather strap depends on multiple factors: type of tannage (vegetable vs. synthetic), leather quality, frequency of use, exposure to moisture and perspiration, and proper maintenance. Generally, a quality shell cordovan lasts 5-7 years with intensive daily wear. A good quality alligator or calf has an average lifespan of 3-5 years. Vegetable tanned leather develops patina and improves aesthetically over time, while synthetic straps have more predictable durability but less visual character. Milano Straps guarantees 18 months on bespoke straps, but with proper maintenance their lifespan is significantly extended.
