Circadian Monster Automatic Watch

The Monster Circadian is an elevated take on our flagship dive watch, made for any wrist and every occasion. Inspired by the natural 24-hour circadian cycle of day and night, this timepiece honors each passing second.

Shinola took the iconic lugs and profile of the Shinola Monster and slimmed the shape into a refined, warm 36mm case that looks and feels balanced on the wrist. Alternating brushed and polished surfaces give the case and bracelet three-dimensional character. And the signature Monster dial styling accentuates the sophisticated glossy alabaster dial. An exhibition caseback reveals the automatic movement at work.


Intentionally designed to fit both men and women, this timepiece makes a universally stunning addition to any watch collection.
