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

The lug width is 18 mm. This is the distance measured between the inside of the two lugs of the case. It is essential to verify it with a digital caliper before ordering a strap, as an incorrect measurement compromises the fit and aesthetics of the watch.

For Sedna Gold, alligator in dark brown or cognac tones amplifies the natural warmth of the alloy. Alternatively, vegetable-tanned calf offers minimalism and elegant aged patina. Shell cordovan is ideal for those seeking exceptional character and superior longevity. The choice depends on usage context and personal wardrobe.

Strap replacement is done by unscrewing the lugs with a dedicated tool (spring bar remover) or by getting help from a professional. The Omega 131.55.29.20.99.006 uses 18 mm straight lugs. It is advisable not to apply excessive force to avoid scratching the Sedna Gold. If you are not experienced, contact Casati Milano for a strap change executed with artisanal craftsmanship.

Yes, any strap with an 18 mm lug width is compatible. However, the quality of the leather, the thickness of the material, and the finish of the buckle determine how the strap integrates aesthetically with the Sedna Gold. Bespoke leather straps from Casati Milano ensure optimal compatibility in both technical and visual terms.

A quality vegetable-tanned leather strap, worn daily, lasts 3-5 years. Shell cordovan, thanks to its natural compactness, can last 7-10 years. Alligator offers intermediate longevity of 4-6 years. Durability increases if you wear the watch occasionally. Casati Milano provides an 18-month warranty on bespoke straps.
