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

The lug width of the Omega Constellation 131.25.29.20.99.001 is 18 millimetres. This value is critical: it represents the precise distance between the pins that anchor the strap to the lugs of the case. An 18mm strap fits perfectly without overhang and without risk of movement. Always verify this value with a digital caliper before purchasing an aftermarket strap.

The most elegant straps for the 131.25.29.20.99.001 are made from alligator (fine grain, dyed black, burgundy or navy blue), vegetable-tanned calf leather with natural tannage, and shell cordovan for those seeking exceptional quality. For sports or casual use, high-tenacity nylon NATO straps or rubber with ergonomic profile are suitable. Alligator is the most coherent choice with the luxurious aesthetics of the bicolour Sedna Gold and steel case with meteorite dial.

The bracelet on this Constellation model is integrated into the case and cannot be removed through standard procedure. The strap is inserted into the same lugs as the bracelet via the pins. Use a spring bar tool to remove the lateral pins, extract the original strap, and position the new strap in the same configuration. It is recommended to have this operation performed by a specialised workshop to avoid scratches on the gold and meteorite case.

Yes, any strap with an 18mm lug width (measured between the pins) is compatible with this Constellation model. Always verify the technical specifications from the seller: the tolerance must be exact. Straps from reliable sources (artisanal or specialised brands) offer superior quality and durability compared to generic online straps.

A high-quality leather strap (alligator, vegetable-tanned calf or shell cordovan) correctly installed on an Omega Constellation has an average lifespan of 3-5 years, with variability depending on daily use, exposure to sweat and level of maintenance. A rubber or technical rubber strap lasts longer (5-7 years), while a nylon NATO strap can exceed 7 years. Rotating between multiple straps significantly extends the life of each individual piece.
