A Flyback Chronograph & Perpetual Calendar! That’s quite a combination. In fact, not only the timepiece is beautifully executed but has also 2 large displays for the Date & Month. Four discs are integrated in the calibre 89801! A very challenging idea mechanically knowing that they are connected to the leap year at 6 o’clock.

Another nice achievement is the use of the crown exclusively to set all indications, making its usage very easy and comfortable. At 6 o’clock is a small seconds hand with the leap year window inside.

The Flyback Chronograph is wonderful and very smooth, specially when the central hand goes back to zero and continues to run. You can see the chronograph time measurement at 12 o’clock on a well balanced and clear display.

The open back is appreciable with a skeleton oscillating weight and some great finishing. If i have to describe the PORTUGIESER PERPETUAL CALENDAR DIGITAL DATE-MONTH in three words, i would say: Elegent, Classic, Well proportioned.

Well done! IWC.
