Tissot PRX 40mm Powermatic 80 — Black Dial, Steel Bracelet
About this watch
Design
The black-dial PRX is the stealthiest take on Tissot's 1970s icon. A slim tonneau case and integrated steel bracelet form one continuous line, while the deep black sunburst dial plays quietly under the light and lets the polished applied indexes do the talking.
Movement
It runs on the Swiss-made Powermatic 80, a self-winding automatic that charges from your wrist and stores around 80 hours of reserve. The exhibition caseback reveals the movement working behind the scenes.
Wear & water resistance
The 40mm case wears slim and modern, easy under a shirt cuff yet substantial on the wrist. Sapphire crystal resists scratches and 100m (10 ATM) of water resistance handles swimming and everyday splashes.
Who it's for
For the person who wants maximum versatility in one watch. Black goes with everything, making this the safe-but-never-boring choice for work, travel and evenings out.

Questions & answers
Is this a manual or automatic watch?
It is a Swiss automatic. The Tissot Powermatic 80 movement winds itself from the natural motion of your wrist, so there is no battery to replace. Left unworn it holds about 80 hours of power reserve, roughly three days.
What happens if it stops after sitting unused?
That is normal for an automatic once the reserve runs down. Just wear it again or wind the crown gently for about 20 to 30 turns, then reset the time and date and it will keep running.
Can I wear it swimming or in the shower?
It is rated to 100 meters, 10 ATM, which comfortably handles hand washing, rain, and swimming. Make sure the crown is pushed in fully, avoid pressing it underwater, and keep it away from hot showers, saunas, and steam.
What size is the case and will it fit me?
The case measures 40mm with a slim tonneau shape and an integrated steel bracelet, a unisex size that flatters most wrists. Links can be added or removed to dial in the fit.
How scratch resistant is the glass?
The watch is fitted with a sapphire crystal, among the hardest materials in watchmaking. It strongly resists everyday scratches and keeps the dial looking clear for years.
Is it genuine Tissot and is it covered by a warranty?
Yes. It is a brand-new, authentic Swiss Made Tissot delivered with its box and papers, backed by a 2-year international warranty. Returns are welcome in line with our store policy.
Customer reviews
The black waffle dial PRX 40mm is the ultimate everyday watch. The 70s integrated bracelet design is iconic and catches light beautifully.
The Powermatic 80 movement runs perfectly. The brushing on the case makes it feel like a watch that costs five times as much.
Because the first link doesn't articulate fully, it wears slightly larger than 40mm. Just keep that in mind. Still an easy 4 stars.
I got this for his birthday and he hasn't worn anything else. The black dial makes it super versatile for suits or casual wear.
The hype around the PRX is real. The finishing on the case and bracelet is completely unmatched for the price point. Highly recommend.
