IWC Schaffhausen Portugieser Chronograph New Edition (With In-House Caliber and See-Through Back)

IWC Schaffhausen has unveiled a reworked version of the Portugieser Chronograph. The iconic design, with its clean, open dial, two recessed totalizers and flange with quarter-second scale, remains unchanged. Inside the case of the much-loved chronograph, however, IWC now uses a high-quality in-house movement from the 69000-calibre family, which can be seen through the transparent back.

The Portugieser Chronograph is one of the most popular watches ever to emerge from Schaffhausen. The open, clean, functional dial, with two recessed totalizers at “6 o’clock” and “12 o’clock”, appliquéd Arabic numerals and slim feuille hands, is encircled by a filigree bezel.

Externally, the iconic design of the new models, which are grouped under Reference 3716, remains unchanged. The decisive new feature is hidden away inside the watch: the IWC-manufactured 69355 calibre ensures the precise display and measurement of time.
