Frequently asked questions

What is the exact lug width of the Omega Constellation 131.20.25.60.13.001?

The Omega Constellation 131.20.25.60.13.001 has a lug width of 16mm. This measurement corresponds to the distance between the spring bars that hold the strap in place. It is essential to verify this measurement when purchasing a replacement strap to ensure perfect compatibility. All of our 16mm straps have been tested on this specific reference.

Which strap pairs best with the two-tone Sedna Gold and steel Constellation?

For the 131.20.25.60.13.001, we recommend a cognac or tobacco alligator strap that echoes the warmth of Sedna Gold without competing visually. Alternatively, a vegetable-tanned calf leather that develops patina over time offers versatile everyday wear. For those preferring maximum formality, a black alligator or shell cordovan strap creates a refined and elegant effect.

How do you change the strap on the Omega Constellation 131.20.25.60.13.001?

The Constellation uses standard 16mm spring bars. To change the strap, a dedicated tool (spring bar tool) is required to remove the pins from the lugs. If you lack this expertise, we recommend entrusting the work to our specialists at the Casati Milano atelier or a qualified watchmaker. Detailed instructions are provided with every order.

Can an aftermarket strap compromise the authenticity of my Constellation?

No, a replacement strap does not affect the authenticity of the watch, which is guaranteed by the case and movement. However, it is advisable to preserve the original Manhattan bracelet. Our 16mm straps are specifically sized for the 131.20.25.60.13.001 and offer artisanal quality comparable to original Omega equipment.

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

A quality leather strap, particularly in alligator or shell cordovan, has an average lifespan of 3-5 years with daily wear. <a href="/pages/termine-glossario/concia-vegetale">Vegetable tanning</a> develops a beautiful patina but requires periodic maintenance. Factors such as humidity, sun exposure, and frequency of wear influence longevity. We offer regeneration and replacement services at Casati Milano with an 18-month warranty.
