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

The Omega Constellation 131.10.29.20.52.001 features an 18 millimetre lug width. This measurement uniquely identifies strap compatibility and is determined by the distance between the two lugs protruding from the case. Always verify this measurement before purchasing an aftermarket strap, as compatibility depends exclusively on this dimension.

There is no single 'best' option, but rather different choices for different needs. For formal elegance, alligator in blue or black tones remains the reference. For everyday versatility, vegetable-tanned calf offers natural texture and a patina that ages beautifully. For durability, shell cordovan guarantees superior longevity. The choice depends on context of use and personal aesthetic preferences.

The strap is replaced using a spring bar tool, a small flat instrument that allows you to compress the lug pins and remove them from the case. Insert the tool's tip into the lateral hole of the pin, compress gently, and the pin releases. Reverse the process with the new strap. If you are not experienced, rely on an authorized service centre or specialist craftsman.

All straps with 18mm lug width are compatible with the Constellation 131.10.29.20.52.001, regardless of brand. Compatibility is guaranteed by lug width dimension, not by strap origin. Milanostraps offers artisanal straps in numerous material and colour variants, all certified 18mm and ready for dispatch.

Durability depends on leather quality, usage and maintenance. A quality watchmaking-grade alligator strap, worn moderately, lasts 4-6 years before requiring replacement. Shell cordovan, being more robust, can last 7-10 years. Vegetable-tanned calf requires more frequent maintenance but develops a fascinating patina. Casati Milano warranty covers 18 months of normal use.
