Seiko 5 Sports SKX series

The Seiko 5 Sports SKX series is widely praised for its value, robust build, and powerful lume, with owners appreciating its comfortable bracelets and improved movement featuring hacking and hand-winding. Some owners find the original SKX models heavy and bulky, while others praise their ruggedness and iconic dive watch design. Reviewers note the 38mm models offer great value at around €350 and are exemplary gateway watches, though their 100m water resistance without a screw-down crown makes them unsuitable for diving. The Seiko 5 Sports SKX series is seen as a decent watch, especially under £200, but lacks the tool watch capabilities of the original SKX, missing a screw-down crown, bezel pip, and ISO rating. On balance, owners and reviewers rate the Seiko 5 Sports SKX series well for its blend of value, improved movement, and tool-watch aesthetic, despite some missing dive certifications.

Tedoro Harmony 36mm Stainless Steel Seiko NH35A

The Tedoro Harmony 36mm Stainless Steel Seiko NH35A is built around the reliable Seiko NH35A automatic movement, with owners reporting accuracy around +/- 5 seconds per day. The 36mm case size is noted as being a custom build, incorporating parts from AliExpress and an Invicta Pro Diver, with specific mention of gold hour and minute hands. On balance, owners find the Tedoro Harmony 36mm Stainless Steel Seiko NH35A to be a satisfactory custom build, appreciating the reliability of the NH35A movement and the familiar styling.
