MWC are one of the largest manufacturers of high performance military watches and the leading supplier to the military, police forces and airline crews. The watches they produce are robust and built to survive the most extreme of conditions, meaning they are more than equipped for the rigours of day to day wear. The 21 Jewel 300m Auto Submariner Watch is MWC's latest automatic diving inspired design, kitted out with a kinetic system and secured in place with their signature 20mm NATO strap.
