Strap for Premier B01 Chronograph 42 Red Gold / Grey / Nubuck / Wheels & Waves

The lug width of the Breitling Premier RB0118A31B1X1 is 22mm. This measurement is taken with a digital calliper across the internal distance between the lugs, perpendicular to the case axis. A 22mm strap tapered to 20mm at the buckle is the optimal configuration to complement the proportions of the 42mm case.

For the red gold version of the Premier, a vegetable-tanned alligator strap in tobacco, chocolate or burgundy tones is the most coherent choice given the dress-chrono vocation of the watch. Alternatively, a whiskey or cognac shell cordovan strap offers a characteristic mirror-like surface that harmonises naturally with the warm chromatic palette of 18-carat red gold.

Strap replacement is performed using a fine-tipped or flat spring bar tool, applying gentle lever pressure on the spring bar housed between the lugs. It is advisable to work on a soft surface to protect the red gold case from scratches. Original Breitling spring bars have a diameter of 1.8mm; when replacing, stainless steel screw-end spring bars are recommended.

Yes, several artisan manufacturers produce aftermarket straps compatible with the 22mm lug width of the Premier. milanostraps.it offers a selection of alligator, vegetable-tanned calf leather and shell cordovan straps made to measure, with a curved attachment profile to fit the Premier's lug geometry precisely, eliminating any visible gap between case and strap.

The lifespan of a leather strap depends on the quality of the hide and frequency of wear. A high-quality alligator or shell cordovan strap, with regular use and proper care — avoiding prolonged exposure to perspiration and moisture — can last between 3 and 6 years while retaining structural and aesthetic integrity. Vegetable-tanned leather straps develop a natural patina over time that enhances their character.
