Strap for Villeret Répétition Minutes Automatique White Gold

The lug width of the Blancpain Villeret 6635-1542-55B is precisely 21 millimetres, measured wall-to-wall between the case spring bars. This dimension is derived from the case proportions (40mm diameter) and is critical for strap compatibility. Any deviation in strap width will result in improper seating on the lugs and visual imbalance.

For a white gold Blancpain Villeret 6635-1542-55B, alligator is the primary recommendation due to its material resonance with precious metal, or alternatively vegetable-tanned calf for those seeking a softer hand and intimate aesthetic. Both develop a patina over time that enhances overall refinement. Technical rubber is acceptable for summer wear, whereas NATO fabric contradicts the civil and formal inspiration of a true dress watch.

Strap replacement involves removing the two spring bars (spring-loaded pins) that connect the strap to the case lugs. Using a spring bar tool, compress each pin to release it from its seat, then extract the old strap and insert the replacement. Given the delicate nature of this dress watch and its precious metal construction, professional assistance from a specialised watchmaker is highly recommended.

Vegetable tanning promotes superior longevity and more compelling patina development compared to synthetic tanning.
