Editor’s Note: Watches & Wonders (formerly SIHH) has moved online and Baselworld 2020 is canceled, but that hasn’t stopped watch brands large and small from debuting their new wares. Stay on top of this year’s best new watch releases here.
The Slim d’Hermès line, in all its various iterations, is one of our favorites of modern watchmaking. The lightness of the case design, the typeface, the mechanics — everything is just right. The time-only and GMT versions both speak their own language in a way that feels both modern and timeless.
The Arceau L’heure de la Lune, which debuted at last year’s SIHH, is a brilliant take on the moon phase complication that sees the main time and date displays spin around the dial. Both watches have been updated for 2020 with new livery.
Slim d’Hermès GMT

For 2020, Hermès has introduced a rose gold version of the GMT with a blue dial and sunburst chapter ring. Powered by the H1950 manufacture-calibre automatic movement, the 39.5mm watch is just 9.48mm thick — incredibly thin for a mechanical GMT watch.
