Strap for Traditionnelle Perpetual Calendar Ultra-Thin Pink Gold / MOP

The lug width of the Vacheron Constantin Traditionnelle 4305T/000R-B947 is 16mm. This measurement refers to the internal distance between the two lugs of the case and is the precise dimension required for a strap to fit correctly without lateral play.

For the Traditionnelle in 18kt pink gold, the most appropriate materials are smooth-belly alligator — in burgundy, midnight blue or tobacco — and shell cordovan, which develops over time a patina that harmonises beautifully with the warm reflections of pink gold. A vegetable-tanned calf leather offers a more relaxed alternative without compromising the elegant character of the piece. The recommended closure is a pink gold pin buckle or a 16mm butterfly deployant clasp.

The strap is replaced using a thin-blade screwdriver or a springbar tool to remove the spring bars housed within the lugs. It is essential to use tools covered or wrapped in soft cloth to avoid scratching the pink gold surfaces. If you are inexperienced with strap changes on precious metal cases, it is advisable to entrust the operation to a watchmaker or the Casati Milano atelier.

Yes. Any strap with a 16mm attachment width is dimensionally compatible with the Traditionnelle 4305T/000R-B947. Milanostraps.it offers a dedicated selection of 16mm straps in various materials and finishes. For the best aesthetic result and longevity, artisan leather straps or premium materials with a pink gold buckle are strongly recommended.

The lifespan of a leather strap depends on the material, care, and frequency of use. A quality alligator strap, rotated with others and kept away from water and excessive perspiration, can last between three and six years while retaining a presentable appearance. Shell cordovan offers superior durability due to its dense fibre structure. All Casati Milano straps carry an 18-month warranty against manufacturing defects.
