De Ville 4300.31.00— lug 20mm

The lug width is 20 millimetres. This dimension is the fundamental design constraint for selecting a compatible strap: verify the distance between the two lateral lugs of the case, which must be exactly 20mm. It is a precise standard, not approximate.

It depends on the context of use. For maximum formality, brown alligator or black shell cordovan with a silver buckle. For everyday elegance, brown vegetable-tanned calf, which develops patina over time. For versatility, black calf, which works with practically every look. All must be 20mm lug width.

Use a spring bar tool (a small V-shaped metal instrument) to extract the elastic pins. Position yourself in a well-lit area. Press the pin from one side, lift the strap from the case, then reinsert the pin into the new strap ensuring both ends are firmly anchored. If you are not experienced, consult a watchmaker.

Yes, provided the lug width is actually 20 millimetres and made by a qualified maker. Milano Straps guarantee construction precision and certified compatibility. The real variable is the quality of the leather, the execution of the buckle, and the strength of the stitching.

It depends on the tanning method and usage. With vegetable tanning and moderate use, 3-5 years before considering restoration. Shell cordovan, being denser and more resistant, lasts 5-7 years or more. Leather degrades with direct sun exposure, salty sweat, and excessive humidity. Rotating between 2-3 straps prolongs the life of each one.
