The Trident wrist mount luminous compass with side view windows and strap includes a large, easy to read face, combined with added premium features. The 2.25" diameter face glows in the dark and includes a ratchet bezel with large markings. Rugged, 1" wide strap is 15" long and includes buckle holes along its entire length, for a secure fit regardless of wrist size. Cutaway windows on all four sides ensure you can get an accurate reading from any position.Color: BlackDiver's waterproof compass, worn on the wrist like a watch2.25" diameter face glows in the darkCutaway windows on all four sidesRatchet bezel with large markings1" x 15" strap with buckle holes along entire length
