The retro design, taken from the well-known Big Pilot's Watch 52 T.S.C., gives this magnificent navigational instrument in bronze a character of its own. The Big Pilot’s Watch Heritage is inspired by the design of the iconic Big Pilot’s Watch Calibre 52 T.S.C. Thanks to this, the timepiece with an impressive diameter of 46 millimetres features a striking retro look. A soft-iron inner case protects the movement against the effects of magnetic fields. The watch is powered by the IWC-manufactured 52110-calibre movement. It features an efficient Pellaton automatic winding system with parts made from black or white ceramic. With the help of two barrels, it builds up a reserve of 7 days. The brown calfskin strap further underscores the heritage character of this timekeeper.
