De Ville 5942.30.31— lug 19mm

The lug width is exactly 19mm. This dimension is critical for choosing the correct strap: any compatible strap must have a maximum width of 19mm to fit perfectly between the lugs of the case without creating gaps or overhang.

Alligator is the natural choice for this white gold timepiece. The fine and regular grain emphasizes the sophistication of the case. High-quality alternatives include vegetable-tanned calf (organic texture that contrasts with horological precision) and shell cordovan (patina that evolves over time). Sport NATO straps are valid for more casual wear.

The change requires two minor tools: a spring bar tool or a watch-specific tool. Procedure: insert the tip of the tool into the spring bar hole, push inward to release pressure, extract the spring bar. Repeat on the other side. Reverse the process with the new strap, ensuring the spring bar is fully in position. If you are unsure, consult a professional watchmaker.

Absolutely yes. Any strap with a 19mm lug width is compatible with the 5942.30.31. Online you will find numerous options already available; at Casati Milano it is possible to commission custom straps by personally choosing the leather, color, and stitching thread, with an 18-month warranty.

Durability depends on use and leather quality. A good quality alligator or calf, with vegetable tanning, offers an operational life of 3-5 years with daily wear. Shell cordovan, being more robust, can last 5-7 years. Leather aging is not deterioration: it is patina. With minimal maintenance (avoid prolonged immersion, dry after perspiration), the strap maintains elasticity and superior appearance longer.
