About the IWC 79350

IWC takes the 7750 base and finishes, regulates and partly re-engineers it; the 7750 piece explains what the base gives it. The 79350 removes the small seconds and the calendar, leaving a chronograph with a 30-minute counter at 12 o'clock and running seconds at 6, and runs at 28,800 vph with a 44-hour reserve and 31 jewels at 30 mm across. It succeeded the 79240 around 2007 with a changed finish and no other difference, and the in-house 69355 replaced it in the Portugieser Chronograph in 2020.

In the library it powers 66 Portugieser Chronograph 3714 references, in a 40.9 mm case that was for years IWC's best-selling watch, 5 Portofinos and 3 Ingenieurs. 19 references are limited editions.

The 79320 is the same base with its day and date in the Pilot's Chronograph, and the 76240 the hand-wound split-seconds version in the Portugieser Chrono-Rattrapante.
