Product Information
The Suunto DX black silicone with black buckle strap kit is a replacement strap for the Suunto DX dive computer, built from black silicone with a matching black buckle and designed to fit Suunto DX and D9tx dive computers.
Who it is for
This strap kit suits Suunto DX or D9tx owners who need to replace a worn, stretched or damaged factory strap, or who simply want a fresh black silicone strap with a black buckle for daily wear and diving. It is a straightforward, direct-fit accessory rather than a sizing upgrade, so it is best for divers keeping the same watch case and wanting factory-style fit and look restored.
