The quiet automatic
Atria Automatic
The smallest case in the collection gives Atria a refined presence. Leather keeps the pairing understated, equally at home with a shirt or a more relaxed sleeve.

Beyond the numbers
A different way to wear the day.
Two places, one glance
Meridian GMT
Between Atria and Rook in diameter, Meridian balances a readable travel dial with a more substantial steel bracelet. It has a firmer physical presence than the leather-strapped Atria.
Explore MeridianBuilt past the pavement
Rook Automatic
The largest diameter in the collection gives Rook a deliberate presence. Its textured rubber strap keeps the character practical, with less weight than Meridian’s steel-bracelet configuration.
