Seiko - 5 Sports "Sea Urchin" Automatic - 7S36-03C0

This commandingly proportioned aquatic instrument is a highly celebrated modern classic, affectionately known among global collectors as the "Sea Urchin." Built to the rigorous engineering standards of the Seiko 5 Sports lineage, it serves as the ultimate bridge between heavy-duty aquatic dive tool aesthetics and dependable daily mechanical performance. Visible through its clear exhibition caseback, it houses the 23-jewel Seiko Caliber 7S36 automatic movement, a self-winding technical workhorse admired by purists for its uninterrupted mainspring power and low-maintenance longevity.

The case architecture features a solid, brushed stainless steel profile with prominent crown guards and a tactile black 60-minute elapsed time diver bezel. The dial is a masterclass in high-contrast visibility, displaying a deep matte black face set with oversized luminescent hour plots, bold sword hands, and a framed bilingual Roman/English day-date window at 3 o'clock. Completed on its factory solid-link stainless steel bracelet with a double-locking clasp and backed by a 10-bar (100m) water resistance rating, this iconic daily driver offers an unmistakable wrist presence.
