Bell & Ross
Instruments BRSWHCERAMICSRB— lug 20mm

The lug width of the Bell & Ross BR S White Ceramic BRSWHCERAMICSRB is 20 millimetres. This measurement is the standard for mid-sized watches and ensures compatibility with a wide range of artisanal and commercial straps. To measure the lug width correctly, position a digital calliper on the internal attachment points of the case, measuring from shoulder to shoulder on the inner lug: the result must be exactly 20 mm.

There is no universally 'best' strap, but rather optimal choices depending on intended use. For formal aesthetics with contrast, a dark brown alligator strap creates maximum visual separation from the white case. For sophisticated monochromatic harmony, pearl grey vegetable-tanned calf is ideal. For daily versatility, vegetable-tanned calf offers customisable ageing patina. Cotton NATO straps add conscious sportiness. Material selection fundamentally modifies the watch's perceived personality: the rectangular geometry remains constant; the character transforms entirely.

Strap replacement requires a spring bar tool (precision instrument for removing/inserting attachment pins). Procedure: (1) position the spring bar tool in the lateral recesses beneath the lug; (2) compress gently downward to release one of the two pins; (3) extract the old strap; (4) insert the new strap, aligning the lug with the pins; (5) compress the pin until you hear the locking click. The operation demands millimetre precision to prevent scratches on the ceramic case. We recommend having this performed by a specialised atelier if you lack experience.

Any strap with a 20 millimetre lug width is technically compatible. Milano Straps offers a specialised collection of artisanal 20mm straps, customisable in leathers (alligator, vegetable-tanned calf, shell cordovan), colours, blade thickness and stitching thread. Aesthetic compatibility depends on your preferences: noble materials emphasise the form's rigour; neutral colours preserve the white ceramic's purity; bold colours inject distinctive personality.

Durability depends on material quality, tanning method, usage conditions and maintenance. A high-quality alligator strap typically lasts 8–12 years with daily wear. Vegetable-tanned calf can exceed 10 years, developing rich, personalised patina over time. Chrome-tanned straps (synthetic tanning) usually last 5–7 years before structural failure. Factors accelerating wear: extreme humidity exposure, acidic perspiration, frequent showers, very high temperatures. Periodic maintenance (cleaning, drying, conditioning cream application) significantly extends strap lifespan.
