Strap for Villeret Ultraplate Automatique 40mm Red Gold / Opalin Frappé

The lug width (ansa width) of the Blancpain Villeret 6651C-3642-55A is fixed at 22mm. This dimension is standard for the model and ensures perfect fit with compatible straps. To verify, measure with a digital calliper the internal distance between the two case lugs in the strap attachment area.

For an elegant dress watch like the Villeret 6651C-3642-55A in red gold, we recommend alligator (black, dark brown or cognac), Japanese shell cordovan with natural tanning, or European calf in vegetable tanning. Alligator is the most formal and sophisticated choice; shell cordovan evolves over time with an extraordinary patina; vegetable-tanned calf offers sustainability and elegant grain.

The strap on the Villeret 6651C-3642-55A is changed using a spring bar removal tool. Insert the thin end of the tool into the spring bar slot, apply gentle inward pressure to compress the spring and remove the bar from the lug. Repeat on the other side. Insert the new strap by aligning the holes with the lugs and compressing the spring bars until you hear a click.

Yes, any strap with a 22mm lug width is compatible with the Villeret 6651C-3642-55A. Ensure the lug width is exactly 22mm: verify with a digital calliper before purchase. Avoid straps with a passant (loop) that is too tight, as this could cause slipping on the case lug.

A premium leather strap (alligator or shell cordovan) on a regularly-worn dress watch typically lasts between 4 and 7 years. Durability depends on frequency of use, ambient humidity and maintenance. Leather that is thoroughly dried after water exposure and stored in a non-excessively dry environment maintains flexibility and strength for longer. Vegetable-tanned straps tend to develop a fascinating patina over time, ageing elegantly.
