The refined proportions and contrasting materials create sophisticated elegance for medium wrists.

Frequently asked questions

What is the lug width of the Omega Constellation 111.25.36.10.52.002?

The lug width is 20mm. This is the inner distance from shoulder to shoulder of the protrusion that supports the strap. It is the reference value for choosing any compatible strap: neither 18mm (too loose) nor 22mm (excessive force on the case).

What is the best strap for the Omega Constellation 111.25.36.10.52.002?

For this model with mixed red gold and steel case, we recommend ventral alligator in black or brown for classic elegance. If you prefer a patinated aging effect, vegetable-tanned calf leather in caramel or cognac tones pairs perfectly with the red gold and develops character over time.

How do I change the strap on my Omega Constellation 111.25.36.10.52.002?

Use a spring bar tool: position the fork under the spring that supports the pin, gently push downward to release the pin from the lug cavity. Repeat on the other side. Reverse the procedure to mount the new strap. If you are unsure, a professional watchmaker will complete it in 5 minutes with guaranteed precision.

Can I use non-Omega aftermarket straps on my Constellation 111.25.36.10.52.002?

Yes, provided they respect the 20mm lug width. Artisanal quality straps (alligator, cordovan, vegetable-tanned calf) often exceed OEM strap standards in craftsmanship and aging. Always verify that the strap shoulders fit smoothly to the case without forcing.

How long does a leather strap last on an Omega watch worn daily?

An artisanal quality alligator or shell cordovan strap lasts 5-7 years with careful maintenance (drying after perspiration, avoiding extreme moisture). Vegetable-tanned calf leather, being softer, lasts 3-4 years before requiring replacement, but develops a patina that many collectors appreciate aesthetically as a sign of authentic wear.
