Strap for BR-X1 Tourbillon Chronograph Carbone Forgé

The lug width of the BRX1-CHTB-CE-CF is 24mm. This is a specific measurement for this 45mm case, proportioned to the horizontal dimensions of the case. It is not the conventional standard of 20 or 22mm, so it is important to verify compatibility before purchasing an aftermarket strap.

The ideal strap depends on intended use and personal preference. For an elegant approach, we recommend alligator with medium grain or vegetable-tanned calf leather, which develop patina over time. For aeronautical authenticity, a military grey NATO or vulcanised rubber strap respects the technical brief of the case. Cordovan shell in burgundy offers sophisticated chromatic contrast.

Strap changing requires specific tools: a strap tool with a pin suited to the 24mm lug width, or watchmaker's tweezers. Insert the pin into the hole on the case lug and apply gentle pressure in the opposite direction to slide the pin outwards. Once removed, the old strap comes off. Repeat the process with the new strap, verifying symmetrical alignment of the terminals.

Yes, provided the strap features an actual 24mm lug width. Many standard straps on the market utilise 20 or 22mm systems, so verify specific compatibility with the supplier. Milano Straps' 24mm straps have been tested and confirmed compatible with this case.

Durability depends on leather type, tanning method, and usage intensity. Vegetable-tanned calf develops patina for 2–4 years of daily wear but maintains structural functionality longer. Alligator typically resists 3–5 years under normal conditions. Cordovan shell, due to its material density, can exceed 7 years. Seasonal rotation between straps extends the life of each by reducing concentrated wear.
