About the IWC 79320

IWC takes the 7750 base and rebuilds it to its own standard, which the 7750 piece describes: the cam-actuated chronograph, the 6-9-12 counter layout and the day and date at 3 o'clock are the base's, and the finishing, regulation and a 44-hour reserve at 28,800 vph with 31 jewels are IWC's. At 30 mm across and 7.9 mm high it is a thick movement, and the 43 mm and 42 mm cases around it reflect that.

In the library it sits under 30 Pilot's Watch references, the Chronograph ref 3777 of 2016 at 43 mm and the ref 3717 of 2006 at 42 mm, including the Le Petit Prince and Spitfire editions, 14 GST Aquatimer chronographs and 5 Portofino Chronographs. The 43 mm case accounts for 19 references and the 42 mm for 17. 18 are limited editions.

The 79230 is the split-seconds version of the same base, the 79350 the Portugieser's variant without the day and date, and the 69375 the in-house family that succeeded it.
