Vestal Guide Watch, Black, Signs of use but not abuse. The Vestal Guide Watch is more than just a great looking digital timepiece. It's also an altimeter, a barometer, and a compass. The premium multi-sensor digital movement is encased in a 48 mm surgical-grade stainless steel case and scratch-resistant crystal. Check out the altitude readout paired with an elevation-gain graph. Then use the barometer, which alerts you to rough weather, should you attempt to make the ascent. And you'll need a compass to keep your bearings straight. The custom polyurethane strap is comfortable, waterproof, and incredibly durable.
