Should you buy the Tissot PRX Powermatic 80 Blue 40mm?
The Tissot PRX Powermatic 80 Blue 40mm is for someone who wants a Swiss automatic with a thin case and a weekend-proof reserve. At $850.00 it ranks #4 of 10 in our Automatic Watches category and is the most expensive watch here. Take it off Friday night and it should still be running Monday morning. If you like the integrated look but not the price, the Citizen Tsuyosa NJ0150-56X costs $371.25. If you want Swiss in a field style, see the Hamilton Khaki Field Titanium H70555533.
Where it earns its score
- 80-hour reserve. The Powermatic 80 runs about twice as long off the wrist as the 41-hour Seiko 4R36 and 4R35 calibers.
- Thin case. The 40mm 316L steel case is 10.93mm thick, far slimmer than the 14.1mm Invicta Pro Diver 8926OB.
- Sapphire and 100m. A sapphire crystal and 10-bar rating cover daily knocks and swimming.
- Quick-change bracelet. The integrated bracelet is interchangeable and closes with a push-button butterfly clasp.
What to know first
- Warranty is the lowest factor at 66. Tissot's 2-year international warranty trails Citizen's 5 years and Seiko's 3 years.
- Price. At $850.00 it costs 2.3 times as much as the Citizen Tsuyosa NJ0150-56X, which scores higher overall.
- Not a dive watch. Tissot rates the 100m case for recreational swimming and showering, not diving or snorkeling.
Our verdict
The Tissot PRX Powermatic 80 Blue 40mm scores 82, a Good Buy and #4 in our Automatic Watches category. Quality (90) and Features (90) are the best here, but Value (74) and Warranty (66) pull it down. Buy it if you want Swiss finishing and an 80-hour reserve. If price matters more than the Swiss badge, the Citizen Tsuyosa NJ0150-56X (86) is the better buy.
