Strap for De Ville Master Chronometer 34 Stainless Steel / Brown MOP - Diamond

The lug width of the De Ville 434.13.34.20.57.001 is 16 millimetres. This is a specific and non-standard dimension: any aftermarket strap must respect this tolerance with precision to ensure stable and correct attachment to the case lugs. It is measured in the flattest area of the lugs using a digital calliper.

The choice depends on intended use. Alligator represents the pinnacle of formality for professional meetings and evening occasions. Vegetable-tanned calf is more versatile and suited to daily wear. Shell cordovan is ideal for those who love deep patinas and extreme durability. A NATO strap or satin rubber strap transforms the De Ville into a more casual weekend instrument while maintaining visual proportions.

Strap replacement requires the use of a specific tool (spring bar tool) to extract and insert the elastic lugs (spring bars) that hold the strap to the case lugs. It is a delicate operation: it is advisable to consult a professional to avoid scratching the case. Casati Milano offers personalised assistance for these interventions.

Any strap with a 16mm lug width is compatible with this model. On milanostraps.it you will find a curated collection of 16mm straps in alligator, calf, shell cordovan and other materials, all customisable in sizes, initials and stitching thread. The Casati Milano atelier also creates bespoke straps with personal choice of leathers.

The lifespan of a leather strap depends on the material and daily wear. A good quality alligator lasts 3-5 years with regular use. Vegetable-tanned calf resists 2-4 years. Shell cordovan, being notoriously hard, can last 5-7 years or more. Humidity and sweat accelerate wear. Straps made by Casati Milano include an 18-month warranty.
