Overview

The Seiko SUT068 is an everyday watch from the Diamond Collection collection. It has a 27 mm stainless steel case, 7.5 mm thick. Inside is a solar movement (calibre V137) with about 6 months (4,380 h) of power reserve. You also get 50 m water resistance, a hardlex (mineral) crystal and a bracelet.

Who it suits

  • Wrists of roughly 10.4–12.3 cm (4.1–4.9 in), by our Watch Finder sizing guide
  • Desk and dress wear (keep it away from swimming)
  • Shirt cuffs and smarter dress codes
  • Grab-and-go wear without winding or setting

Strengths

  • Solar charging with about 6 months (4,380 h) of reserve
  • Slim at 7.5 mm

Trade-offs

  • Hardlex (mineral) crystal scratches more easily than sapphire
  • Only 50 m water resistance: splash-proof, not for swimming
