Depth rated to 100M, 20mm, oil filled, and never needs a battery. This is the exact compass we build into every Expedition Watch Band Compass Kit, cut loose here to ride on its own, wherever you decide it lives. Custom cardinal dial inspired by the classic VN era WCC wrist compass. It shrugs off 100 meters of water, so river crossings and clumsy boat launches are none of its concern. The cardinal points glow after dark, so losing the sun doesn't mean losing your heading. Drop it in a pocket, a survival tin, or pop it into our Expedition Watch Band Compass Kit and forget it's there until you need it. The WCC wrist compass used during the Vietnam War is the grandfather of the modern titanium wrist compass, the piece PDW first brought to market in 2015. The dial on this 20mm button compass is a direct descendant of that original. Specifications: Materials: Compass: Oil Filled* with an Polycarbonate Body *PLS note that any oil filled compass may have tiny bubbles appear and disappear over time as a result of changes in altitude and barometric pressure. This does not affect the performance or accuracy of the compass unit. Approx. Dimensions: Compass: .787" X .314" / 20mm X 8mm Approx. Weight: 0.56oz / 16g Features: Depth Rated to 100 M Water Resistance Black Face with Luminous Glow in the Dark Cardinal Markings Custom Printed Dial with WCC-Inspired Cardinal Point Markings FAQ What is a button compass used for?Think of it as insurance. A tiny backup heading source for the moment your phone dies, your GPS loses signal, or your main compass walks off without you. Toss it in a pack or lock it onto a watch band with our EWBC kit, no weight added, no battery required. Is this compass waterproof?Yes, to 100 meters. Rain, river crossings, and the occasional dunking that proves you can't swim as well as you claimed, none of it stops this thing from pointing north. What does the WCC Arrow mark on the dial mean?It's a nod to the WCC wrist compass carried during the Vietnam War, the compass that led PDW to build the first titanium wrist compass in 2015. We pulled the dial straight from that original and updated it into this 20mm button compass. Is this the same compass used in the Expedition Watch Band Compass Kit?Yes. This is the same 20mm compass that ships inside every Expedition Watch Band Compass Kit, available here on its own if you need a spare or a replacement. Does it need batteries?No. It reads the earth's magnetic field, the same trick compasses have used for centuries. No batteries to swap, no charge cable to pack, no firmware update standing between you and north.
