Tudor Black Bay Sailcloth FKM Rubber Strap with Deployant Clasp - Black

Black on Black Bay. The default pairing and the one that works on every Tudor reference without exception.

FKM rubber with a sailcloth-embossed texture on the top surface and a brushed stainless steel deployant clasp pre-fitted. The black colourway disappears against the Black Bay's dark dial and bezel, letting the watch do the talking while the strap handles the daily work. On the BB58 with gilt indices, the black sailcloth frames the warm dial tones without competing. On the BB41 or GMT with silver accents, the black creates clean contrast. On the Pelagos, it matches the tool watch intent. Black is the colourway that never clashes and never dates.

The sailcloth texture catches light differently to smooth rubber. In direct sun, the embossed weave pattern creates subtle depth across the surface. Under artificial light, it reads as matte black. That shift between textured and flat depending on the light is what makes sailcloth more interesting on the wrist than plain rubber, without the maintenance issues of genuine fabric.

The deployant clasp folds shut in one motion. Once sized, the watch goes on and comes off with a single click. No threading. No fumbling. The clasp distributes pressure evenly across the wrist and protects the strap from the daily stress that pin buckles cause at the hole point.

Complementary clasp engraving available. Up to three characters, laser engraved into the stainless steel for a permanent, precise finish.

Tudor Compatibility Guide:

20mm: Black Bay 58 (ref. 79030, 79010), Black Bay 58 GMT, Black Bay 54 (ref. 79000), Black Bay 68 (ref. 79018), Black Bay Pro (ref. 79470), Ranger (ref. 79950), Monarch (ref. M2639)

22mm: Black Bay 41 (ref. 79680, 79683), Black Bay GMT 41 (ref. 79830, 79833), Black Bay Chrono (ref. 79360, 79363), Black Bay Ceramic, Pelagos 42 (ref. 25600, 25610)

This strap does not fit: The Pelagos 39 uses 21mm, which is not available in this strap. The original Black Bay Bronze (ref. M79250) uses a non-standard 23mm lug width and is not compatible. The BB58 Bronze (ref. 79012) uses 20mm and fits.

Important: Tudor has introduced 21mm lug width on selected newer Black Bay 41 METAS-certified references (2025 onward). The standard BB41 (ref. 79680, 79683) remains 22mm. If you own a 2025 or later BB41, measure between the inner edges of both lugs to confirm whether your watch is 21mm or 22mm before ordering.
