Strap for Constellation Manhattan 29 Co-Axial Master Chronometer Stainless Steel / MOP

The lug width is exactly 18mm. This dimension is proportionate to the 29mm case diameter and is essential to ensure compatibility with aftermarket straps. Any strap you mount must have a maximum width of 18mm at the attachment seat.

It depends on the context of use. For formal occasions, we recommend superior grade alligator or vegetable-tanned calfskin, which enhance the rigorous case finishes. For daily wear, FKM rubber with subtle texture or NATO fabric offer practicality without compromising elegance. The color should harmonize with the dial: on a silver dial, dark brown or black are natural choices.

The change requires a specific tool to remove the spring bars. Measure the distance between the case lugs: it must be 18mm. Remove the two bars with the dedicated tool, extract the old strap, insert the new spring bars and mount the new strap, ensuring it is perfectly aligned with the case. If you are not experienced, consult a certified watchmaker.

Yes, provided they respect the 18mm lug width. Verify that the strap is free from thickness defects and that the grain, in the case of leather, is uniform. Omega permits the use of compatible straps without voiding the warranty, provided the change is performed correctly and does not damage the case.

A superior grade alligator strap, with regular maintenance (monthly cleaning, biannual conditioning), lasts 3-5 years. Vegetable-tanned calfskin ages more quickly (2-4 years) but develops a fascinating patina. Durability depends on frequency of use: daily wear reduces strap life compared to occasional use.
