The IWC Da Vinci 36 Moonphase IW4593 was launched in late 2016 in anticipation of SIHH 2017. It marks a return of the style of the original 1985 Da Vinci Perpetual 3570, with a stepped round case and movable lugs. The IW4539 has a case of 36mm, which houses the self-winding caliber 35800 with moonphase indicator. With reference IW4593-08, the case is done in red gold while the dial is silver. The bronze-colored alligator strap is by Santoni.
