Strap for BR-X1 Tourbillon Chronograph Rose Gold

The lug width of the BRX1-CHTB-PG is 24 mm. This measurement remains constant across all material variants (rose gold, stainless steel, titanium) and represents the calibrated balance point for the 45 mm case diameter. To verify compatibility with your strap, place a digital calliper perpendicular to the inner lug shoulders of the case. If your watch already wears a strap, measure the width of its base where it connects to the lugs.

Grade-A alligator leather represents the optimal choice. The material contrast between the natural grain of the leather and the luminosity of rose gold creates a sober yet refined balance, reinforcing the watch's instrumental identity. Alternatively, shell cordovan in dark shades (mahogany brown or burgundy) emphasises the aeronautical heritage, whilst vegetable-tanned calf leather offers daily versatility and develops natural patina over time.

Strap changes on this model are executed via spring bars (lever bars) threaded through the lugs between the case shoulders. Procedure: remove the watch and position it face-up on a soft surface, use a spring bar tool or fine flathead screwdriver to gently depress one spring bar towards the case centre (freeing one end), release the old strap from the opposite side, repeat on the other lug. Installation of the new strap reverses this process: ensure both spring bars are correctly seated in the lug slots.

Yes, absolutely. The 24 mm lug width renders the BRX1-CHTB-PG fully compatible with certified aftermarket straps of matching specification. However, selection of straps manufactured to elevated quality standards (natural leather, welded stitching, robust spring bars) is advisable to respect the watch's finish and durability expectations. Artisanal straps from Milano Straps guarantee total compatibility and personalisation in sizing, material, and thread colour.

Longevity depends upon three variables: frequency of wear, leather choice, and maintenance discipline. A grade-A alligator strap, worn moderately (4–5 days weekly) and kept dry, offers estimated durability of 4–6 years before stitch regeneration becomes necessary. Shell cordovan, owing to its structural density, may extend to 6–8 years. Vegetable-tanned calf, with natural ageing, endures 5–7 years whilst maintaining pleasing aesthetics. Critical variables are ambient humidity, prolonged solar exposure, and body perspiration (which acidifies leather). Storage in controlled climate (40–50% humidity, darkness) between wearings extends functional lifespan.
