Strap for Classima Executives GMT

The lug width of the Classima 8734 is precisely 18mm. This dimension represents the distance between the two attachment points of the bracelet to the case. It is the fundamental technical specification for selecting compatible straps and must be verified by measuring the internal space between the case lugs.

The choice depends on intended usage. For formal occasions, we recommend dark brown alligator or burgundy shell cordovan. For daily versatility, vegetable-tanned calf in cognac or hazelnut tones offers elegant patination over time. For casual-smart contexts, cotton NATO or grey FKM rubber maintain the watch's minimalism without chromatic excess.

The change requires a specific tool for removing spring bars or the use of a thin flat screwdriver. Gentle pressure must be applied at the lateral attachment points of the case. It is advisable to use a professional to avoid accidental scratches on the steel case. Compatible 18mm straps install in minutes with the original spring bars.

Absolutely yes, provided it respects the 18mm lug width and presents a total leather width of less than 4mm to guarantee fit at the case lugs. Artisanal straps with brushed steel deployante offer complete compatibility and often improve ergonomics compared to the integrated bracelet, thanks to ease of length adjustment.

Durability depends on material, usage, and maintenance. Quality vegetable-tanned calf guarantees 3-5 years with moderate daily wear. Shell cordovan, being denser, can reach 5-7 years. Alligator and crocodile maintain structural integrity for 4-6 years. Natural patina and micro-separation of stitching points represent physiological ageing, not defects.
