Grand Seiko SBGX359vsTissot PR 100

The Grand Seiko SBGX359 is lauded for its technically advanced 9F51 quartz movement, enabling a compact 33mm x 9.1mm stainless steel case and offering ±10 seconds per year accuracy. Reviewers highlight the refined finishing of its Snowflake dial and 100 meters of water resistance. However, it comes with a US$3,200 price tag, representing a $500 increase over prior 9F models. Overall, reviewers praise the Grand Seiko SBGX359 for its compact dimensions and precise quartz movement at the specified price point.

Owners widely praise the Tissot PR 100 for its excellent value, with specific mentions of its sapphire crystal, 100m water resistance, and the 80-hour power reserve of its Powermatic 80 movement. Reviewers and owners consistently highlight its pleasing winding action and strong lume. Accuracy figures for the Powermatic 80 COSC variants are reported as -2 seconds per day or +/- 1-2 seconds per day. Some owners note that the crystal attracts fingerprints and that the black finish on some bracelets can wear off after extended daily use. A single owner of a quartz model experienced a recurring issue where the watch stopped for periods weekly, which was not resolved by a battery replacement. Overall, owners and reviewers rate the Tissot PR 100 highly for its exceptional value and robust features, particularly its durable construction and reliable movements.
