IWC Ingenieur Perpetual Calendar Digital Date-Month Review

IWC Ingenieur Perpetual Calendar Digital Date-Month, a 45mm-wide and 17.5mm-thick piece in 18k red gold, based on what is a truly impressive movement, the IWC Caliber 89800. Built on the same 89000 foundations as the Chronograph Sport, this piece further adds a perpetual calendar to the mix, spiced up with digital indications for the month and date at 2 and 10 o'clock, respectively. More IWC clone watches.

A neat design tweak is how the apertures are framed by what appear to be sub-dials – although the functionless tracks on their periphery might come across as a design no-no in the eyes of watch design purists.

From the back, it does look comparable to other 89xxx chronographs, as the perpetual calendar's module has naturally been fitted onto the dial side (otherwise, you'd have all the important displays and indications way below the plane of the dial, not to mention that the chronograph bits reserve the back of the movement anyway). For now, it is available in this version with a silvery-white dial limited to 100 pieces.
