Strap for De Ville Master Chronometer Yellow Gold / Silver

The lug width of the Omega De Ville 434.53.40.20.02.002 is 19 millimetres. This dimension is specific to this model and is essential to verify before purchasing a strap. You can check it by measuring the internal distance between the lateral lugs of the case with a calliper.

Alligator remains the most classic choice, ideal in black, dark blue, or burgundy. Alternatively, vegetable-tanned calf leather offers a more rustic texture and a patina that evolves naturally over time. Shell cordovan is also excellent for durability and lustrous finish. The choice depends on the occasion: ceremonies require alligator, everyday wear benefits from calf leather.

The procedure is straightforward: place the watch on a soft surface, locate the pin connecting the strap to the lugs (accessible from the internal side of the case), and use a pin remover or small screwdriver to gently push the pin out. Once removed, the old strap separates. Insert the new strap by aligning the holes with the lugs, then reinsert the pin. Avoid forcing to prevent damaging the case.

Only if the lug width is identical (19mm) and the width is compatible with the case. Not all 19mm straps are the same: some may have the pin positioned differently. The safest solution is to purchase straps specifically sized for the De Ville 434.53.40.20.02.002. MilanoStraps offers selections of tested 19mm straps.

A quality alligator strap, with regular maintenance (gentle cleanser, protective cream every 4-6 months), lasts an average of 2-3 years. Vegetable-tanned calf tends to wear more slowly but is more sensitive to humidity. Shell cordovan is the most durable (4-5 years). Daily wear accelerates deterioration; a strap worn occasionally lasts longer. Casati Milano offers an 18-month warranty on their work.
