Instruments BRSBLCERAMICSRB— lug 20mm

The Bell & Ross Instruments BRSBLCERAMICSRB features a 20-millimetre lug width, measured internally between the lugs of the case. This dimension is mandatory for mechanical and aesthetic compatibility with any aftermarket strap.

Alligator leather in fine grain or vegetable-tanned calf in dark brown represent the most coherent choices with the ceramic case aesthetics. For a sportier interpretation, a NATO in dense cotton or grey or black offers functionality and swift replacement capability. Your choice depends on context of use and desired formality level.

Strap replacement is performed by extracting the spring bars that secure the lug to the case. Use a spring bar removal tool or a small flat-head screwdriver positioned beneath the spring to lift it, then extract the bar. Repeat on the opposite side and insert the new strap's lug. Verify that the spring bars are firmly seated before wearing the watch.

Yes, any strap certified for 20mm lug width is mechanically compatible. Aesthetic compatibility, however, depends on construction quality and material: prioritise alligator, vegetable-tanned calf, or dense fabric NATO, avoiding glossy leathers or chromed finishes that would conflict with the ceramic case's sobriety.

A high-quality alligator or calf strap typically lasts 3-5 years of regular use, depending on humidity exposure, heat and daily wear. Vegetable-tanned leather develops patina over time, retaining aesthetic character even after 5-7 years. Periodic maintenance (treatment with colourless balm) significantly extends the strap's lifespan.
