Strap for Constellation Manhattan 29 Co-Axial Master Chronometer Yellow Gold / Champagne

The Omega Constellation 131.50.29.20.58.001 features an 18mm lug width. This measurement should be taken by positioning a rigid ruler or digital caliper perpendicular to the case attachment lugs. All 18mm straps from the milanostraps.it collection are compatible with this model without any modifications required.

For the Omega Constellation 131.50.29.20.58.001 in yellow gold, we recommend a cognac alligator strap (medium golden-brown tone) to maintain chromatic harmony, or a pure black alligator for maximum elegant contrast. Alternatively, vegetable tanning develops a golden patina over time that naturally harmonizes with the gold case. For intensive daily use, traditional calf leather offers immediate softness and rapid adaptation.

The strap is changed by extracting the attachment lugs from the case using a dedicated tool or a pointed pin. Position the watch on a soft cloth with the space between the case and strap facing you. Gently push the lug from one side until it slides out; remove it completely with tweezers. Repeat on both sides. Thread the new lugs through the compatible 18mm strap and reinsert them into the case until fully engaged.

Yes. The Omega Constellation 131.50.29.20.58.001 is compatible with any strap featuring an 18mm lug width. On milanostraps.it the 18mm strap collection offers dozens of artisanal options in exotic leather (alligator), vegetable tanning, shell cordovan, calf, and synthetic materials, customizable in dimensions, initials, and stitching thread color.

The lifespan of a leather strap depends on material and intensity of use. A well-constructed alligator strap lasts 3-4 years with moderate daily use; shell cordovan reaches 5-7 years thanks to the density of its fibrous structure; traditional calf offers 2-3 years. Vegetable tanning develops a protective patina that extends lifespan beyond 4 years. Leather exposed to moisture, frequent perspiration, or extreme temperatures requires regular maintenance (cleaning with a damp cloth, conditioning every 6-12 months) to maximize longevity.
