The Slim d’Hermès Quantième Perpétuel immediately draws the gaze. The numerals with their font specially designed by Philippe Apeloig stand out with light and airy grace. While the date, month, dual-time and leap year indications are displayed on various counters, a mother-of-pearl moon phase graces an aventurine sky backdrop at 3 o’clock. The elegant and graphic dial melts seamlessly into the surrounding precious rose gold and titanium or titanium and platinum case.
The remarkably technical ultra-thin Manufacture H1950 movement is equipped with one of the most demanding horological complications: a perpetual calendar. This authentic ‘mechanical memory’ ensures that the date of months with 30 and 31 days is automatically adjusted, while taking account of leap years by indicating February 29th every four years without any need for corrections. Adorned with a ‘sprinkling of Hs’ and meticulously hand-bevelled, the movement also powers day/ night, dual-time and moon-phase indications within a composition measuring just 4mm thick. This impressive demonstration of horological expertise may be admired through the sapphire crystal case-back.
