Strap for World Time Geneva Harbor 7131

The lug width of this model is 20mm, measured as the distance between the centres of the attachment holes on the case. This dimension is specific to the Complications ladies' model and requires proportionately sized straps to maintain the watch's aesthetic balance.

Natural alligator leather in champagne, beige, or taupe tones is the reference choice for this rose gold model. It represents the optimal compromise between elegance, durability, and harmonisation with the patina of the metal. Valid alternatives include vegetable-tanned calf and shell cordovan for more refined contexts.

The strap is exchanged using specialised tools (primarily a spring bar tool or precision screwdriver) to compress the elastic pins that secure the strap to the lugs of the case. It is advisable to entrust the operation to a specialist watchmaker, as the rose gold case is sensitive to scratching.

Yes, with due care. A high-quality aftermarket strap with 20mm anchors and a maximum thickness of 4mm is compatible with the 7131/175R-001. Avoid excessive thickness that could compromise the fit to the lugs. Always consult an expert craftsman before proceeding.

A high-quality leather strap (alligator, cordovan, vegetable-tanned calf) has an average lifespan of 5-8 years with regular maintenance. Durability depends on frequency of use, exposure to moisture, and conservative care. A well-maintained strap can exceed a decade of service.
