Editors’ Notes

This graphic edition of Hermès Timepieces' 'Heure H Au Carré' watch is both artful and timeless. Made in Switzerland from stainless steel, the monogram-shaped case is lacquered to match the diamond-encrusted color-blocking across the square dial. The strap has been handcrafted with alligator from the maison's own prestigious trove and is interchangeable, too.

Each Hermès 'Heure H Au Carré' watch comes with instructions on how to change the strap and a tool to enable you to do so.

We offer a two year warranty for all working parts and any manufacturing faults.
