This is a Vacheron Constantin Overseas dedicated rubber strap. Pins for attaching the buckle are not included. I believe it can be attached to a 41mm model, but please check for yourself if it can be fitted. It is new, but has been taken out of the bag, so I'm listing it as "like new." Please refrain from purchasing if you are overly concerned about condition. Returns are not accepted, so please purchase at your own risk.
