Overall, owners appreciate the Marathon Arctic OSAR 41mm Automatic for its comfortable fit and Marathon's overall appeal.

Nodus Unity

The Nodus Unity is praised for its novel design, featuring a fixed ceramic bezel and a textured sunray dial, and its slim 36.5mm case. It is powered by a Miyota 9015 movement, regulated to ±8 seconds per day, with a 41-hour power reserve and 150m water resistance.
