Internal Development IWC Schaffhausen

The much-loved Portugieser Chronograph from Swiss watch brand received an internal upgrade this year. The brand now uses a high-quality in-house movement from the 69000-calibre family—namely the IWCmanufactured 69355 calibre—which is visible through the transparent back. The iconic design of the collection—with its clean, open dial, two recessed totalizers at 6 and 12 o’clock and flange with quarter-second scale—remains unchanged in the new models, which are grouped under reference 3716. Six different models available in 18-carat 5N gold or stainless steel. All of them boast a power reserve of 46 hours.
