Seiko Prospex U.S. Special Edition SPB357

This U.S. Special Edition Prospex looks to underwater caves for its design story. The textured blue dial evokes the changing tones of submerged cave walls, while the dark-coated titanium case and bracelet give the watch a more shadowy character than a conventional polished diver. A two-tone unidirectional bezel adds another layer of contrast and lets you track elapsed time.

The 43.5 mm titanium case and bracelet have a black super-hard coating, with sapphire crystal and an anti-reflective inner coating. Seiko's automatic 6R35 movement offers approximately 70 hours of power reserve, and the watch is rated to 200 meters for scuba diving.

Our Take

We like that the cave inspiration isn't just a shade of blue. The textured dial and dark titanium case work together to suggest the low-light underwater setting, while the long-running automatic movement makes it an easy watch to keep in rotation.
