Strap for Constellation Manhattan 29 Co-Axial Master Chronometer Stainless Steel - Diamond / Lilac Supernova / Bracelet

The lug width of the Constellation 131.15.29.20.60.001 is 18mm. This dimension represents the distance between the two lateral lugs where the strap attaches. To verify it, position a millimeter ruler perpendicular to the case and measure from the inner edge to the inner edge of the lugs. Precise measurement is essential to avoid incompatible purchases.

The best strap depends on the occasion: for formal events, black alligator or black shell cordovan amplify the elegance of the silver dial. For daily wear, vegetable-tanned calf in dark brown tones offers versatility and captivating patina over time. Cognac shell cordovan creates a magnificent contrast with the steel while maintaining aesthetic authority.

Changing the strap on the Constellation 131.15.29.20.60.001 is straightforward: use a spring bar tool to compress the small lateral springs of the lugs, remove the old strap and insert the new one by aligning it with the holes in the case. The lugs must snap perfectly into their lateral housings without play or abnormal tension. If you lack experience, a professional watchmaker takes only a few minutes.

No, a strap with an 18mm lug width is specific to models that mount that width. The Constellation 131.15.29.20.60.001 is not compatible with watches requiring 16mm, 20mm or other sizes. However, several Omega women's collections and third-party brands use 18mm, so the strap can transfer between models with the same dimension.

The lifespan depends on the material and usage. An alligator or shell cordovan strap typically lasts 3-5 years with regular daily wear, thanks to the density and fiber resistance. A vegetable-tanned calf, more delicate, may require replacement after 2-3 years if exposed to heavy stress. Exposure to moisture, sweat and UV rays accelerates aging. With proper care (frequent drying, avoiding submersion), the lifespan extends significantly.
