The Slim d’Hermès has, in the blink of an eye, turned 5. Since it was introduced as a fresh and handsome ultra-thin, modern classic watch, it’s repeatedly caught our attention with the careful choice of designs, added functions and stunning fonts that Hermès specially developed with Philippe Apeloig for this watch. Suffice to say our creative director loves this font, and so do we.

What’s notable about Slim d’Hermès is that it’s truly a modern classic watch, and unlike other brands that have taken modernism to mean new materials or surface treatments, the Slim d’Hermès interprets modern classicism purely in terms of design. And like all Hermès products, the use of the simplest of lines, and gentle details — multi-layered dials, finishing techniques — bring out the beauty of the watch.

The latest to the Slim d’Hermès range is a GMT model, with an additional ultra-thin module that’s developed by Agenhor for Hermès, and retro-fitted to the H1950 in-house movement. The dial feels like a study in design proportions — on the 39.5mm rose gold case, it appears as if concentric rings, gently broken up by a larger GMT counter at 10 o’clock and a smaller date counter at 6, frame your view of time.

The silver, grained GMT counter has a single hand to display the hour, with two day and night indicators to its right under ‘L’ and ‘H’ for local and home times. The date display, decorated with snailing and encircled in gold, feels like a reflection of the entire watch. A pusher at 10 o’clock controls the hour adjustment for the GMT function, while the regular time-setting crown is in its usual place. It’s a handsome watch that, at 9.48mm thin, is quite slim and easily fits under a shirt cuff.

The watch is priced at USD 19,675 before taxes.
