- Automatic dive watches Every watch here is self-winding and rated as a diver’s watch by its maker — a designation tied to the ISO 6425 standard, not just a rotating bezel on a sports case. Sorted by the lowest total price you can pay right now. 95 items on sale from USD 69.99
- Solar G-Shock G-Shock models powered by Casio’s Tough Solar: light keeps the battery charged, so there is no battery change to plan for. Many also set their own time by radio signal or Bluetooth — check each model’s specs. 274 items on sale from USD 68.89
- Spring Drive Seiko’s own movement: powered by a mainspring like a mechanical watch, but regulated by a quartz crystal and an electromagnetic brake — so the seconds hand glides instead of ticking. Mostly Grand Seiko, plus a few Seiko models. 36 items on sale from USD 898.00
- Titanium watches A titanium case weighs about 40% less than a steel one and does not contain the nickel that some people react to. Seiko, Citizen and Casio each use their own hardened or coated titanium — the case material is listed on every page. 189 items on sale from USD 74.16
- Watches 38 mm and under Smaller cases sit better on slim wrists and slide under a shirt cuff. Everything here measures 38 mm across or less, by the case diameter shown on each watch’s page. 378 items on sale from USD 31.99
- Automatics with sapphire crystal A self-winding movement under sapphire — a crystal far harder to scratch than mineral glass, and usually kept for pricier watches. A sensible filter when picking a first mechanical watch. 440 items on sale from USD 72.49
