Black Shark Skin Strap for the Graham Silverstone GMT

The Graham Silverstone GMT is a big, motorsport-styled chronograph that shrugs off subtlety. It wants a strap with the same nerve. A black shark skin strap for the Graham Silverstone GMT gives it a hard-wearing exotic hide that matches the watch's attitude, cut to 70/115 mm with quick-release bars.

The problem is texture. A smooth calf strap disappears against a case this assertive, and a rubber strap turns it into a gym watch. Shark skin holds its own.

Why these choices

Shark is one of the toughest exotics we work with. The grain has a dense, tooth-textured surface that catches light differently across the strap, so black shark never looks flat the way black calf can. On a sport chronograph that gets worn hard, that durability is a practical choice as much as an aesthetic one.

We kept it black to let the watch lead, and cut it to 70/115 mm to sit trim under a large case rather than swimming past the keeper. Quick-release spring bars let the owner swap straps without tools, useful on a watch that rotates through a collection. An 18 mm classic stainless buckle keeps the hardware clean and matches the case.
