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 highquality in-house movement from the 69000-calibre family, which can be seen through the transparent back.

Not without reason has the Portugieser Chronograph proved to be 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. The flange, printed with a quarter-second scale, enables precision reading of stopwatch times and gives this timeless Portugieser a subtle, sporty touch.

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. The rugged, precision chronograph movement with the classic column-wheel design can be seen through the transparent back. An automatic pawl-winding system builds up a power reserve of 46 hours.

Six different versions are available in 18-carat 5N gold or stainless steel. The stainless-steel models are equipped with the newly developed butterfly folding clasp, which is particularly comfortable in wear. All the steel models retail for EURO 7.950, the 18k 5N rose gold for EURO 17.700.
