Simplicity doesn’t always come in basic packages. This is certainly the case for the Slim d’hermès Quantième Perpétuel Platine, which packs in a highly complex perpetual calendar function. Originally released in gold last year, the timepiece is now offered in platinum and presents the collection’s signature Arabic numerals (by graphic designer Philippe Apeloig) in a silver tone, set against a dark blue dial and accented by rhodiumplated hands. Like its predecessor, the ticker is powered by the ultra-thin Manufacture H1950 movement and shows the date, month, second time zone and moon phases across four separate counters. For added realism, the moon phase disc features a moon made of mother-of-pearl and a night sky made from aventurine.
