Referencing the first digital watches IWC built in 1884 and more recently launched in 2009 the IWC Portugieser Perpetual Calendar Digital Date 75th Anniversary Edition (Ref.3972) combines the desirable chronograph function with a bold digital date and month perpetual calendar. The new model utilises the Caliber 89801 (featured in last years 49mm Aquatimer) which received praise for its ease of use, with all adjustments made via the crown and requiring no correction until year 2100.
The watch is unmistakably gorgeous yet poses some questionable features such as the ‘DATE’ and ‘MONTH’ text below the digital displays and the case size. It would be safe to assume IWC have recognised the popularity of digital displays (which has prompted the release of this timepiece) with watches like the Lange Zeitwerk but unlike the Zeitwerk at 41.9mm this new model is big, coming in at 45mm.
Now I’ve had the pleasure of wearing the Portuguese F.A. Jones Tourbillon which stands at 43.1mm and it feels large on the wrist so it’ll be interesting to see how the Portugieser Perpetual Calendar Digital Date wears with an additional 2mm of gold or platinum.
