IWC · Manual Wind

98245

A hand-wound movement descended from IWC's calibre 98 pocket-watch base, a lineage running back to the designs of founder F. A. Jones. It drives the Portugieser Regulateur, where hours and seconds are given their own subdials and the minutes take the main hand — a regulator layout borrowed from precision workshop clocks. A large screw balance and Breguet hairspring regulate it.
