What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Tissot Seastar 1000

Owners widely praise the Tissot Seastar 1000 for its value, solid build, and 300m water resistance, with reviewers highlighting its comfortable wearability and affordable price point for a sporty diver. Some owners find the bezel difficult to use and note glare from the crystal, while others criticize the lume and bracelet quality, with one owner describing the clasp as flimsy. Accuracy figures for the quartz models are excellent, and the Powermatic 80 movement is considered reliable. Overall, owners and reviewers rate the Tissot Seastar 1000 highly for its strong value proposition as a sporty, affordable everyday watch.

From video reviewers

The 80-hour power reserve from the Powermatic 80 movement is a significant strength. Reviewers did not reach a consensus on any weaknesses.

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.
