Frequently asked questions

What is the lug width of the Omega Constellation 131.20.28.60.02.002?

The lug width of the Constellation 131.20.28.60.02.002 is 18mm. This width is specific to the 28mm case and ensures the correct visual proportion. Always verify with a caliper the distance between the attachment pins before ordering a replacement strap.

What is the best strap for the Omega Constellation 131.20.28.60.02.002?

Vegetable-tanned alligator represents the most refined choice, thanks to its fine grain and the patina that develops naturally over time. Calf leather and shell cordovan offer versatility and excellent resistance. The choice depends on use: formal for alligator, everyday for calf, sport-chic for cordovan.

How do I change the strap on my Constellation 131.20.28.60.02.002?

The strap is replaced by removing the spring bars from the case lugs. Use a specific tool, a spring bar tool, to gently compress the spring and extract the pin. Insert the new strap in the same manner, ensuring that the pins engage securely on both sides.

Can I use an aftermarket strap on an Omega Constellation 131.20.28.60.02.002?

Yes, provided the lug width is exactly 18mm. Quality artisanal straps, crafted in alligator, calf leather, or shell cordovan, pair excellently with the two-tone finish of the Constellation. Verify that the supplied spring bars are compatible or use the original ones.

How long does a natural leather strap last on a daily-wear watch like the Constellation 131.20.28.60.02.002?

A fine leather strap, maintained with care (avoiding prolonged soaking and drying it after water contact), lasts between 3 and 5 years under intensive daily-use conditions. Vegetable tanning and alligator age elegantly, developing a patina that increases the aesthetic value of the timepiece.
