Entry-Level Automatic Diver

The Seiko 5 SRP605K2 is hard to miss. Which, for a dive watch, is exactly the point. Large and luminescent, the hands and hour markers are outlined in gold, while the metallic blue bezel—unidirectional, with white engraved numerals and markers—glows like an eel. Elements also designed for the diver include a rubber accordion strap and a shrouded crown with knurling. Still, at 44 millimeters wide, the SRP605K2 is still small enough for the office. It’s equipped with 21-jewel 4R36 movement, beating at 21,600 vibrations per hour, and offers both hand-winding and hacking seconds.
