Strap for Le Brassus Tourbillon Quantième Perpetuél Chronographe Flyback à Rattrapante Red Gold

The Blancpain Le Brassus 4289Q-3642-55B has a lug width of 22mm. This measurement refers to the internal distance between the two lugs at the lower part of the case and determines compatibility with any aftermarket or replacement strap.

For a red gold haute horlogerie timepiece such as the Le Brassus, a vegetable-tanned alligator strap is the most coherent choice: the regular belly grain complements the dial's refinement and develops a distinguished patina over time. Shell cordovan hand-dyed straps offer a dense, long-lasting surface, while vulcanised rubber is suited to intensive daily wear.

The strap is replaced using a spring bar tool to remove the spring bars securing it to the case lugs. It is advisable to entrust this operation to a watchmaker or specialist atelier to avoid scratching the red gold case, which is particularly susceptible to mechanical abrasion.

Yes: any strap with a 22mm lug width and standard spring bars is compatible with the Blancpain Le Brassus 4289Q-3642-55B. Milano Straps offers a curated selection of handcrafted 22mm straps in various materials and finishes, available with deployant clasp or pin buckle, made to order or ready to ship.

The lifespan of a leather strap depends on the material, tanning method and frequency of use. A vegetable-tanned alligator strap, kept away from excessive moisture and perspiration, typically lasts between two and four years with daily wear. Shell cordovan, owing to its dense fibre structure, tends to last longer. Casati Milano straps carry an 18-month warranty against manufacturing defects.
