This is a custom automatic watch that pays homage to the vintage 1680 red-sub dive watch. The dial is based on the Mark IV type, with 660ft depth notation in an Open Six font. The black dial and the hands have green luminous material.
It uses a Seiko NH35 automatic movement with a custom calendar font that replaces the standard one with an old-style font. The case has a stainless steel bezel with two-way rotation and no click feel, a screw-down crown with a laser-processed S mark, an acrylic crystal and an old-style semi-bubble screw-down case back. All parts are new.
The vintage oyster bracelet has independent end pieces and a folding clasp with an extension function. It is a hobby-built custom watch, so small scratches on parts may be present. The case and crystal differ from the 1680 red-sub model shown on the maker's Instagram.
