Strap for De Ville Master Chronometer 34 Stainless Steel - Yellow Gold / Green / Bracelet

The lug width of the De Ville 434.20.34.20.10.001 is 16mm. To verify this measurement on your watch, use a digital caliper and measure the distance between the centers of the two lugs that support the strap. The result should be 16.00mm ± 0.2mm. The 16mm is a non-standard measurement, requiring straps that are specifically and precisely constructed.

High-quality alligator in dark shades (black, oxblood brown, midnight blue) is the natural choice for the De Ville: the natural grain perfectly complements the sober elegance of the case. A valid alternative is vegetable-tanned calf leather with a fine texture. Satin rubber offers daily practicality while maintaining style. Avoid excessively glossy finishes that would compete with the dial.

Obtain a spring bar tool (fork-shaped instrument). Position your watch on a flat surface with the strap facing upward. Insert the thin tip of the spring bar tool into the small hole at the base of one lug, lift slightly to compress the internal spring, and slide the lug out of its seat. Repeat for the other lug. Reverse the operation when fitting the new strap, ensuring both lugs are fully inserted and snap into place.
