French luxury brand Hermès has extended its minimalist Slim d’Hermès line with a new watch in platinum that’s been entirely crafted in house.

The apparent simplicity of the all-blue-clad Slim d’Hermès Quantième Perpétuel Platine immediately draws the gaze.

The numerals with their font specially designed for the Slim collection 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 platinum case.

The remarkably technical ultra-thin H1950 movement is equipped with one of the most demanding horological complications: a perpetual calendar.

This ensures that the date of months with 30 and 31 days is automatically adjusted, while taking account of leap years by indicating February 29 every four years without any need for corrections.

Adorned with a sprinkling of H’s and meticulously hand-bevelled, the movement also powers day/night, dual-time and moon-phase indications within a composition measuring just 4 mm thick. This impressive demonstration of horological expertise may be admired through the sapphire crystal case-back.

With its new Slim Quantième Perpétuel Platine, Hermès unites the full spectrum of watchmaking skills. Its gleaming platinum exterior provides a perfect setting for mechanical complications to rub shoulders with the skill of case and dial-making artisans, while an abyss blue alligator strap reflecting impeccable leather craftsmanship sets the perfect finishing touch.
