Strap for Constellation Manhattan 29 Co-Axial Master Chronometer Stainless Steel / Sedna Gold / Silver Diamond / Diamond

The Omega Constellation ref. 131.25.29.20.52.001 has a lug width of 18 millimetres. This is the linear distance between the two lugs that emerge from the case and support the strap. Any aftermarket strap must be specifically made for 18 mm lug width to ensure precise and secure attachment.

For the reference 131.25.29.20.52.001 we recommend premium alligator for its regular grain and chromatic harmony with Sedna Gold, or vegetable-tanned calf for those seeking a patina that evolves over time. A brandy-colored shell cordovan strap is extraordinary for emphasizing the Sedna Gold. All should be supplied with a deployant clasp or double-locking buckle.

Changing the strap on the 29 mm Constellation does not require complex tools. Using a small spring bar removal tool, gently push on the bayonet spring that supports the lug from the underside of the case. The lug releases and the strap slides away. Insert the new strap—ensuring it is 18 mm—aligning the lug in the case holes, and allow the spring to close. If you are unsure, a watchmaker can perform the operation in minutes.

Yes, all straps with 18 millimetre lug width are compatible with the reference 131.25.29.20.52.001. However, we recommend also checking the strap thickness—some very thick straps may not slide smoothly under the case lugs. Our straps at milanostraps.it have been tested for compatibility and aesthetic proportion with this model.

A high-quality alligator strap, subjected to correct tanning and periodic maintenance, has an average lifespan of 5-7 years with daily wear. Longevity depends on exposure to humidity, sweat, temperature fluctuations and the frequency of protective balm application. Alligator ages elegantly, developing a patina that increases its aesthetic value. With conscious maintenance, your Constellation strap will remain a reliable companion over time.
