De Ville 4643.20.32— lug 20mm

The lug width of the De Ville 4643.20.32 is 20mm. This intermediate dimension is proportionate to the 41mm case diameter and requires precise compatibility when selecting an aftermarket strap. Measuring the lug width between the two lugs integrated into the case ensures correct selection.

Black or dark brown alligator remains the most elegant choice for a yellow gold watch: the natural grain of the leather imparts visual movement and the chromatic contrast enhances the value of the precious metal. Alternatively, shell cordovan develops refined patina over time, while vegetable-tanned calf offers a more subtle tonal dialogue between leather and gold.

The strap is removed by using a spring bar tool (a thin lever instrument) to compress the spring bars that hold the strap to the lugs. Insert the tool into the space between the lug and strap, compress the lower spring bar, and slide the strap outward. The reverse procedure installs the new strap. If you are not experienced, it is advisable to consult an expert.

Yes, the De Ville 4643.20.32 is fully compatible with quality aftermarket straps constructed for 20mm lug width. Always verify the measurement before purchase and choose reliable manufacturers that guarantee dimensional precision and material quality. Milano Straps offers a selection of 20mm straps tested for this model.

A quality alligator or shell cordovan strap, worn daily with normal exposure to humidity and light, maintains structural integrity for 3-5 years before showing signs of wear at the lug area. Longevity depends on maintenance (periodic cleaning, protection from excessive humidity) and the tanning method used. Casati Milano straps include an 18-month warranty and allow for future upgrades.
