About the IWC 35800

It is the 35111 family, a Sellita SW300 built to IWC's specification, with a moon-phase module on top: 25 jewels, a 42-hour reserve and a beat of 28,800 vph at 25.6 mm across, with the date at 3 o'clock and the moon under a window at 12. The glossary explains the moon phase display.

In the library it powers 16 Portofino Automatic Moon Phase references at 37 mm and 40 mm, in steel and red gold, several with diamonds, and 4 Da Vinci Automatic Moon Phase 36 references of 2017. 2 are limited editions.

The 35111 is the same base without the moon phase, and the 59800 the hand-wound eight-day movement with a moon phase in the 45 mm Portofino.
