The 1982 Professional Diver 1,300m design is still going strong.
The case and bezel are made out of Super Titanium, just like the Citizen.
The surprising lightness may come as a surprise given its voluminous appearance.
Also, it has been finished off with Duratect, which is 5 times or harder than stainless steel, protecting it from scratches and damage in harsh environments while diving.
This wristwatch comes with an extend strap so that it can be worn on top of a wetsuit.
