Frequently asked questions

What is the lug width of the Omega Constellation 131.55.28.60.99.004?

The lug width of the 131.55.28.60.99.004 is 18 millimetres. This width is specific to this model and requires a precise selection of compatible straps. The measurement should be taken on the inside of the case lug using a digital calliper to ensure accuracy.

Which strap is best suited for the Constellation 131.55.28.60.99.004 in Sedna Gold?

Dark brown alligator (cognac tone) represents the ideal formal choice, creating an elegant contrast with the Sedna Gold. Alternatively, vegetable-tanned calf develops a fascinating patina over time. For daily wear, vulcanised rubber straps offer practicality and durability. The choice depends on the context of use and personal aesthetic preference.

How do you change the strap on the Constellation 131.55.28.60.99.004?

Strap replacement requires the use of a spring bar tool. Position the watch on a soft surface to avoid scratches. Insert the tip of the tool into the slot on the lug, gently push the spring bar, and slide the old strap upward. Repeat the operation symmetrically on the other lug. Then insert the new strap, ensuring that the spring bar is perfectly seated.

Which aftermarket straps are compatible with the 131.55.28.60.99.004?

Any strap with an 18 millimetre lug width is compatible with the 131.55.28.60.99.004. Our online collection includes straps in alligator, calf, shell cordovan and rubber, all available in various shades and finishes. We recommend verifying the quality of the lug and the elasticity of the spring bar to ensure compatibility and durability over time.

What is the average lifespan of a leather strap for this model?

A quality leather strap, subject to regular maintenance (cleaning with a soft cloth, treatment with natural balm every 6-8 months), lasts an average of 3-4 years under daily wear conditions. Lifespan varies depending on the quality of the leather, climate and intensity of use. Shell cordovan and vegetable-tanned leather tend to last longer than standard calf, while developing a fascinating patina.
