'Built to go the distance' perfectly describes the whole range with truly impressive features and build quality. These are real watches for the real world. Incredibly functional and cool what more could you want? Well they can make 'special designs / combos' too. The Bloxworth's Swiss-made 13-jewel chronograph movement has a three-year battery life and is secured inside our proprietary shock-absorbing steel movement housing. The 44mm diameter case is machined from solid 316L marine-grade stainless steel case and individually pressure tested to 150m twice during construction then placed in a water-filled pressure vessel at 200m and finished with a hardened anti-reflective mineral crystal for clear vision in all conditions. The dial, hands and 0-20 markers on the bezel all have long-lasting Superluminova detailing that provides outstanding legibility. The outer edge of the bezel is machined for confident grip, and only rotates anticlockwise, so it can only show a shorter remaining time if it's accidentally knocked. The crown and push-buttons are knurled for superior grip in harsh conditions. The caseback is bolted down, not threaded, because it's the best way of holding the shock-absorbing movement housing accurately inside the case. The included tool can be used to adjust the length of bracelet and remove the solid stainless steel strap bars. Bracelets are constructed from 316L stainless steel with solid screw-in link-pins for maximum strength. The heavy-duty clasp has micro-adjustment to fine-tune the fit or extend quickly and elegantly for use over a wetsuit.
