Engraved ‘Big Pilot’s Watch Heritage’ on caseback
The dial is retro-inflected with cream-coloured Super-Luminova for the markers and hands. The hands are blued steel, as they were on the original, Second World War Beobachtungsuhr (navigator’s watch) IWC made for the German airforce. Together, the blue hands and faux-vintage lume explain the Heritage moniker.

This was the first BP using a refined version of the 50000-calibre family with a bidirectional Pellaton pawl-winding system with two barrels for the 7 days’ power reserve (52110 Calibre). The winding pawls and the automatic wheel are now made of black ceramic while the rotor bearing is made of white ceramic. These extremely hard high-tech materials make the automatic winding system practically wear-free. The design and finish of the movement has also been enhanced while the proportions of the rotor and the inset “Probus Scafusia” gold medallion are noticeably slimmer than prior Calibres.
