Strap for De Ville X2 Co-Axial 35 Small Seconds White Gold / White

The Omega De Ville 7710.30.39 is fitted with a 20-millimeter lug width. This dimension is specific to the model and determines the compatibility of any aftermarket strap. To measure correctly, position a digital caliper perpendicularly between the two spring bars, excluding the lugs themselves: the result will invariably be 20 millimeters.

A cognac or dark brown alligator leather represents the most elegant choice for this white gold dress watch. Alternatively, bordeaux shell cordovan develops a sophisticated patina over time, while vegetable-tanned black calf leather offers uncompromising formalism. Avoid technical materials such as rubber or silicone: the 7710.30.39 is conceived for formalism.

Remove the watch from your wrist. Locate the two lateral spring bars on the case. Using a dedicated spring bar tool or remover, gently push one of the spring bars from the inside outward until it disengages. Repeat for the second spring bar. Insert the new strap by first aligning one lug, then pushing the spring bar until it clicks into place. Always use a tool with a plastic or nylon tip to avoid scratching the white gold.

Yes, milanostraps.it offers 20mm straps in noble materials—alligator, shell cordovan, vegetable-tanned calf—customizable in dimensions, thread colors, and initials. Each strap is handcrafted and available both as a catalog product and by commission through the Casati Milano atelier.

A handcrafted alligator or cordovan strap of quality, with selected leather and double stitching, guarantees 5-7 years of daily wear. Longevity depends on individual factors: exposure to perspiration, cleaning frequency, and climate. A properly maintained strap develops an elegant patina rather than deteriorating, transforming over time into a complement even more refined to the watch.
