Frequently asked questions

What is the lug width of the Omega Constellation 131.20.28.60.13.001?

The lug width of this model is 14 mm. To verify it correctly, measure the internal space between the lugs using an analog caliper, positioning it perpendicular to the case. This precision is essential for selecting an aftermarket strap that fits the lugs without lateral play.

Which strap is best suited for the Constellation 131.20.28.60.13.001?

Alligator is the premier choice, with regular grain that pairs beautifully with the Sedna Gold and steel combination. For alternatives: dark shell cordovan offers a deep patina that ages wonderfully, while vegetable-tanned leather ensures sustainability. For casual wear, rubber and NATO fabric straps maintain practicality without stylistic compromise.

How do you change the strap on an Omega Constellation?

Remove the watch from your wrist. Using a spring bar tool, gently press the spring bar mechanism toward the center of the case, gradually lifting one end of the lug from its seat. Repeat on the other lug. To fit the new strap, insert the spring bar into the strap lugs and press the spring toward the center, then align the lugs to the case seats until they click into place.

Are there aftermarket straps compatible with the 131.20.28.60.13.001?

Yes, any strap in 14 mm lug width is compatible with this model. Online you will find ready-to-ship straps, customizable in size, initials, and thread color. For a bespoke experience, the Casati Milano atelier creates custom-made straps with personal leather selection, WhatsApp updates, and an 18-month warranty.

How long does a leather strap last before requiring replacement?

Durability depends on frequency of use, type of tanning, and climate conditions. An alligator or shell cordovan strap with vegetable tanning used daily typically lasts 3-5 years before showing significant wear at the fold. Prolonged exposure to moisture reduces longevity; proper care—drying after water contact and rest in ventilated environments—extends the strap's service life.
