The Archimede DeckWatch pays homage to the designs of early watches used by officers in the navy and on merchant ships. First as pocket watches from the end of the 19th century and later, from around 1910, as wristwatches. Known for their clarity and accuracy they were developed for use in navigation at sea.
The case, in stainless steel, measures 42mm x 10.5mm. It has an AR-coated sapphire crystal and is water resistant to 50 meters.
Movement is the Swiss hand-wound ETA caliber UNITAS 6498 with 17 jewels, 18,000 vph and a power reserve of 46 hours. Leather straps are available in either brown or black. A stainless steel bracelet is also available.
