Strap for De Ville Master Chronometer 34 Stainless Steel / Lavender / Bracelet

The Omega De Ville 434.10.34.20.03.001 has a lug width of 16 millimetres. This measurement is specific to this model and should be measured by positioning a calliper between the internal metal shoulders of the case, excluding the spring bar. Precise measurement is essential to ensure compatibility of the new strap.

For this 34mm dress watch, vegetable-tanned alligator offers maximum refinement with natural patina that evolves over time. Alternatively, vegetable-tanned calf ensures clean elegance and softness. For casual versatility, vulcanised rubber in black or dark blue maintains correct proportions without aesthetic compromise. NATO is not recommended as it does not respect the dress watch identity of the timepiece.

Position the watch on a dedicated case holder with spaces for the lugs. Locate the spring bar (small metal pin) that secures the strap to the case. Using a specialised tool (spring bar remover), push it slightly downward to release the old strap. Insert the new 16mm strap by aligning the holes with the metal shoulders, then reposition and secure the spring bar with symmetrical pressure.

Yes, 16mm straps available from Milano Straps are fully compatible. They are made-to-measure for this lug width and available in multiple materials (alligator, calf, shell cordovan, rubber). Each strap can be personalised in length, initials and stitching thread colour to fit your wrist and style perfectly.

A quality leather strap, such as alligator or vegetable-tanned calf, typically lasts 3-5 years with daily use and regular maintenance. Durability depends on sun exposure, humidity and frequency of use. To extend lifespan, apply protective balms every 6-8 months and alternate with different straps across seasons. Milano Straps offers an 18-month warranty on bespoke straps made at the Casati Milano atelier.
