IWCGST Perpetual Calendar

This obscure and rarely seen GST Perpetual Calendar Chronograph offers an array of complications inside a robust and water-resistant titanium case. Produced between 2001 and 2004, the watch has a distinctly utilitarian aesthetic with its fully brushed case and bracelet.

The dial manages to incorporate a perpetual calendar, moon phase, and chronograph all into 4 sub-registers. Yellow and white accents distinguish the functions and provide high levels of legibility against the black face.

Housed inside the case is IWC’s calibre 79261, which is a highly modified Valjoux 7750 with the addition of renowned watchmaker Kurt Klaus’ perpetual calendar system.

This example from 2001 is presented in good condition with some signs of wear visible on the case and bracelet. Included in the sale are the box and booklets, however, the original guarantee papers are not supplied.  

All watches offered for sale are searched and cleared against The Watch Register database and a certificate is available to the winning bidder upon request.
