Vetehinen Mo Coppoletta III

S.U.F Helsinki Vetehinen Mo Coppoletta III is a 26-piece limited-edition automatic diver’s watch, created as a collaboration with Mo Coppoletta and hand-assembled at the SarpanevaUhrenFabrik workshop in Helsinki.

Built around the Vetehinen diver’s platform, the watch features a 42 mm stainless steel case made from Supra 316L/4435 steel, measuring 11.45 mm thick with a 51 mm lug-to-lug profile. Its one-way rotating bezel is engraved with Mo Coppoletta artwork and filled with Swiss Lumicast, while water resistance is rated to 30 ATM, making it a capable mechanical dive watch.

Dial construction is centred on Tiger Iron stone from South Africa, a natural composite of tiger eye, red jasper and hematite, meaning each dial has its own unique pattern and character. Black hands with Swiss Super-LumiNova provide legibility against the richly textured stone surface.

Power comes from a modified Soprod A10 automatic calibre, running at 28,800 vibrations per hour, or 4Hz. The movement offers hours, minutes and seconds, 25 jewels, a 42-hour power reserve, rhodium plating, perlage and Côtes de Genève finishing.

Supplied with both a handmade black Nordic Elk leather strap and a black natural rubber strap, each measuring 20 mm, the watch is completed with an 18 mm Sarpaneva stainless steel pin buckle.
