Strap for Constellation Manhattan 29 Co-Axial Master Chronometer Stainless Steel / Sedna Gold / Green Aventurine

The lug width of the Constellation 131.23.29.20.99.001 is exactly 18mm. This measurement refers to the internal distance between the two metal lugs of the case. It is an established standard for compact models, and allows access to a wide range of high-quality artisanal aftermarket straps.

For the Constellation 131.23.29.20.99.001, we recommend dark brown alligator straps to enhance the contrast of the Sedna Gold-steel, or vegetable-tanned aniline calf for authentic aging. For a sporty-elegant approach, rubber or NATO straps in 18mm take advantage of the timepiece's water resistance without visual obstruction.

The strap is replaced by extracting the spring bars from the case lugs using a dedicated tool, strap lever, or multi-function tool. Position the watch on a soft pad, locate the spring bar, compress it slightly to release it, then extract it. Insert the new strap following the reverse procedure. If you lack experience, we recommend support from a professional watchmaker.

Yes, absolutely. The Omega Constellation 131.23.29.20.99.001 uses standard 18mm lugs, compatible with any artisanal strap certified for that measurement. Quality aftermarket straps (alligator, calf, rubber) offer aesthetic versatility without compromising the watch's functionality.

A quality leather strap (alligator or natural calf) typically lasts 3-5 years with moderate daily use, developing an authentic patina over time that enhances its character. Longevity depends on frequency of use, water exposure, and maintenance. Casati Milano straps include an 18-month warranty and support for extending durability through personalized regenerations.
