Illustration. The seconds hand sweeps, like the real movement.
Why it's interesting
Built for saturation divers rather than holidaymakers: 1,220 m, a helium escape valve and a Glidelock clasp that extends over a wetsuit. The 43 mm 126600 brought back a red 'Sea-Dweller' line and added a Cyclops over the date, which the previous 40 mm model did without — a big, honest instrument that makes a Submariner look dainty.
