Tudor Black Bay Sailcloth FKM Rubber Strap with Deployant Clasp | 20mm 21mm 22mm

Tudor Black Bay watches take a 20mm, 21mm, or 22mm strap depending on the reference. This sailcloth-effect FKM rubber Tudor watch strap replacement is built specifically for the Tudor Black Bay range, available in 7 colours and delivering the textured, heritage character of traditional sailcloth with the flexibility, water resistance and durability of premium FKM fluoroelastomer rubber.

The Black Bay has always sat between two worlds. It is a serious tool watch with dive credentials, and a refined collector's piece that works just as well on a weekend as it does underwater. This Tudor deployant clasp strap matches that brief precisely. More structured than standard rubber, more resilient than genuine Tudor fabric strap options, and a cleaner, more considered alternative to a traditional Tudor NATO strap. It handles desk time, dive time, and everything in between without asking anything of the wearer.

The brushed stainless steel deployant clasp keeps the profile clean and secure on the wrist. Where a tang buckle stresses the same point daily, the Tudor deployant clasp spreads pressure evenly, opens in one clean motion, and extends the life of the strap significantly. Integrated quick-release spring bars mean the whole strap changes in seconds without tools, ideal for collectors who rotate straps or travel with a spare.

Particularly well suited to Tudor Black Bay Pro rubber strap owners who want the same sporty, water-resistant character with the added security and refinement of a deployant clasp. Available in black, navy, khaki, red, grey, orange, and cream across 20mm, 21mm, and 22mm to fit the full Tudor Black Bay range.

Optional deployant clasp engraving available, up to three characters, laser engraved for a finish that is precise, permanent, and entirely your own.
