Strap for Villeret Ultraplate Automatique Red Gold / White

The lug width (ansa) of the 6223-3642-55 is 20 millimetres. This is the distance between the two spring bar pins on the case. You can verify it by measuring the internal space between the lugs on your watch. A 20mm strap will fit perfectly without any play or forcing.

For the 6223-3642-55 in rose gold, we recommend a dark brown, cognac, or bourbon alligator leather with artisanal craftsmanship and a rose gold deployante clasp. Vegetable-tanned calf leather is an excellent alternative, especially if you desire a strap that ages visibly over time. Those preferring contemporary aesthetics may choose a canvas NATO in neutral tones. Rubber FKM is ideal for those who wear the watch daily without conservative concerns.

Use a dedicated spring bar tool (leva speciale) to gently remove the elastic pins from one side of the case. Do not force: insert the tool into the slot and push the pin inward until it clicks. Once the pin is extracted, you can remove the old strap and insert the new one by aligning the holes. Reinsert the pin with firm pressure until it clicks into position. If uncertain, consult an experienced horologist.

Yes, any strap with a 20mm lug width is compatible. An artisanal quality strap does not compromise the watch's integrity; rather, it allows you to adapt the 6223-3642-55 to different contexts. The crucial factor is selecting a lug manufactured with precision (exact internal clearance, uniform thickness) and a buckle or keeper that respects the case design without overloading it.

A premium leather strap, if properly maintained (avoiding direct water exposure, prolonged humidity, and sweat contact), lasts 3 to 5 years with daily wear. Alligator or vegetable-tanned calf leather age beautifully, developing patina and character. Milanese artisans such as Casati offer an 18-month warranty against manufacturing defects. You can rotate multiple straps to extend the life of each and adapt to different seasons.
