All picks →- 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. 37 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
