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

The lug width is 22mm. This is the distance between the two inner holes of the case lugs. A 22mm strap fits perfectly onto the 42mm case, maintaining optimal proportions between strap width and case diameter. To verify, insert a ruler into the lugs: the measured distance must be exactly 22mm.

For a timepiece of this refinement in rose gold, we recommend alligator with vegetable tanning (which develops a honey patina), aged calf leather (chocolate-brown tonality), or authentic Shell Cordovan (with buttery reflections). These materials elegantly dialogue with the warmth of rose gold. We advise against rubber and NATO fabrics, which are too sporty for a perpetual calendar of this calibre.

Straps are changed via the spring bars positioned at the case extremities, one per side. Use a dedicated tool or thin flat instrument to apply gentle pressure on the spring bars, detaching them from the case holes. Remove the strap, insert the new one, and re-engage the spring bars. If unsure, consult a certified watchmaker.

Yes, any strap with lugs (attachment width) of 22mm is completely compatible. Ensure the lug width is exactly 22mm and the strap thickness is not excessive (recommended: 3-4mm). Bespoke artisanal straps guarantee optimal fit and durability. Always verify dimensions before purchase.

A premium leather strap (alligator, calf, Shell Cordovan) with vegetable tanning lasts approximately 3-5 years with daily wear, developing characteristic patina. Durability depends on: frequency of wear, sun and moisture exposure, leather care. A naturally aged strap is a sign of quality: the patina that forms indicates authentic materiality. Preserve the original strap; you can always have it professionally restored.
