The Le Brassus 2322-3631-55B, seen from the bench

The Le Brassus represents one of Blancpain's most sophisticated complications, equipped with the 2322 caliber that integrates a flying tourbillon with a power reserve indicator. The movement offers indication of hours, minutes and date, with a tourbillon escapement system that improves chronometric precision. The case features 23mm lugs, sized to ensure proper proportion on the wrist.

Frequently asked questions

What is the lug width of the Blancpain Le Brassus 2322-3631-55B?

The lug width of the Blancpain Le Brassus 2322-3631-55B is 23mm. This measurement must be verified by placing a rigid ruler between the two lugs without including the lug thickness itself. It is essential to measure precisely because 23mm is a non-standard width that requires specific straps.

Which strap is most suitable for the Le Brassus 2322-3631-55B in rose gold?

For the Le Brassus in rose gold, we recommend matte alligator in cognac tones, which naturally complements the warmth of the case. Alternatively, vegetable-tanned calf leather in dark brown offers an aged patina that acquires character over time, or shell cordovan for those desiring a more lustrous and dramatic finish. All these materials are available in 23mm lug width.

How do you change the strap on the Blancpain Le Brassus 2322-3631-55B?

The Le Brassus features hidden passage lugs that allow for easy strap changes. Simply locate the two side lugs, use an appropriate tool such as a lug remover to gently slide them out, and remove the old strap. Insert the lugs into the new strap, ensuring the lug width is exactly 23mm before completing the operation.

Which aftermarket straps are compatible with the Le Brassus 2322-3631-55B?

All artisanal straps with a 23mm lug width are compatible with the Le Brassus 2322-3631-55B, provided they are manufactured with standard passage lugs and respect the exact width. We recommend always verifying with the supplier before purchase. On Milano Straps you will find a curated selection of 23mm straps that meet these compatibility requirements.

How long does a leather strap last on a Blancpain Le Brassus?

The lifespan of a leather strap depends on usage and maintenance. A high-quality alligator or shell cordovan strap, with regular use and proper care (periodic cleaning and conditioning), can maintain excellent condition for 5-8 years. Vegetable-tanned calf develops patina more visibly but acquires a fascinating character over time. We recommend rotating straps to distribute wear and inspecting them annually.
