Strap for De Ville Master Chronometer 34 Yellow Gold / MOP - Diamond

The lug width is 16mm. This measurement is the distance between the spring bar pins that protrude from the case lugs. A simple caliper measurement across these pins will confirm that 16mm straps are the correct specification for your timepiece.

For a De Ville 434.53.34.20.55.002 in 18-carat yellow gold, a polished black alligator strap represents the supreme formal choice, creating noble contrast with the metal. Alternatively, vegetable-tanned calf leather in cognac tones offers immediate suppleness and develops a nobilising patina. Shell cordovan produces crystalline luminosity ideal for those who appreciate compact grain. For daily wear, premium FKM rubber ensures practicality without compromise.

Strap replacement requires a spring bar tool to compress the pins and extract them from the case lugs. Insert the tool into the lateral spaces beside the pins, compress gently, then remove the worn strap. Insert the new pins into your bespoke strap, align with the case attachments, then release pressure to snap into position. If uncertain, Casati Milano atelier provides change-out service upon request.

Yes, provided the lug width is exactly 16mm. High-quality artisanal aftermarket straps, such as those available on milanostraps.it, are completely compatible. Always verify that your supplier explicitly states the lug width—16mm ensures perfect proportions on your 34mm timepiece. Avoid generic straps that do not clearly declare this specification.

A premium artisanal leather strap (alligator, vegetable-tanned calf, shell cordovan) typically lasts 5–8 years with regular daily wear, developing an increasingly distinguished patina during this period. Longevity depends on frequency of use, climatic conditions, and care. A strap worn for occasional formal occasions lasts considerably longer. Casati Milano's 18-month warranty covers construction defects; the atelier recommends annual conditioning with specialist products to extend useful life.
