IWC's calibre 52 was developed as early as 1893 and is one of the most tried-and-tested movements. Variants H6 (6 mm high) with added central second above the plate and T (hand-setting through the crown) were used in aviator’s watches and deck watches such as this one. The Hydrographic Department of the Admiralty was established by Order-in-Council in 1795 for the purpose of supplying up-to-date charts and hydrographic information to ships of the Royal Navy, in the first instance from a mass of undigested material accumulated at the Admiralty.
