Strap for De Ville Power Reserve Master Chronometer Yellow Gold / Green

The Omega De Ville 434.53.41.21.10.001 has a lug width of 19 millimetres. This dimension is determined by the geometry of the yellow gold case and is precise: the strap must fit without lateral play between the two lugs. Always verify that the strap is specifically made for the 19mm width to ensure proper fit.

For a formal timepiece such as the De Ville 434.53.41.21.10.001 in yellow gold, we recommend primarily alligator or shell cordovan in cognac brown, burgundy or black tones. These materials enhance the elegance of the case and guarantee durability for many years. For more versatile use, a vegetable-tanned calf leather in tobacco colour offers comfort and natural patina over time.

The strap is changed using a dedicated tool (spring bar tool) to remove the bayonet springs that secure the strap to the lugs. Gently insert the tool into the lateral slot of the lug, compress the spring and slide out the strap end. Repeat for the other lug. The operation requires patience: to avoid damage to the case or lugs, we recommend having it performed by a qualified watchmaker or directly at the Casati Milano atelier.

Yes, milanostraps.it offers a collection of 19mm straps specifically compatible with the De Ville 434.53.41.21.10.001. These straps are crafted with premium leathers (alligator, shell cordovan, vegetable-tanned calf) and customizable in sizes, initials and thread colour. All straps in the collection are tested for proper fit and compatibility with Omega lugs.

Durability depends on the material and usage. A quality alligator or shell cordovan resists 5-8 years of daily use, developing a fascinating patina over time. A vegetable-tanned calf leather lasts 3-5 years under normal conditions. To extend the life of the strap, avoid prolonged exposure to moisture and direct water. The Casati Milano atelier offers an 18-month guarantee on custom-made straps.
