Tissot Seastar 1000

Owners widely praise the Tissot Seastar 1000 for its value and solid build, with one reviewer calling it a comfortable, sporty, and affordable everyday watch with a great case and dial ratio. However, some owners find the Tissot Seastar 1000 too large and poorly proportioned, citing small indices on larger dials and a difficult-to-read bezel. Criticisms also include a non-reflective crystal causing glare, mediocre lume, and a subpar bracelet, with some feeling it is underwhelming for the price compared to other divers. Overall, owners rate the Tissot Seastar 1000 highly for its value and solid build at the price point.

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.
