Tissot PRX 40mm Powermatic 80 — Blue Dial, Steel Bracelet
About this watch
Design
The PRX in blue distills 1970s sports-luxe into a slim tonneau case with an integrated steel bracelet that flows straight out of the lugs. Alternating brushed and polished surfaces catch the light, while the sunburst blue dial shifts from deep navy to bright azure as your wrist moves.
Movement
Inside beats the Swiss-made Powermatic 80, an automatic movement that winds itself as you wear it and banks roughly 80 hours of reserve. Turn it over and the see-through caseback frames the oscillating rotor in motion.
Wear & water resistance
At 40mm with a low profile, it slips easily under a cuff yet still reads as a genuine sports watch. A sapphire crystal shrugs off everyday scratches and 100m (10 ATM) of water resistance covers swimming and daily life.
Who it's for
For anyone who wants a single watch that moves from desk to dinner to weekend. The blue dial is the most versatile in the PRX family, pairing as naturally with denim as with a blazer.

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 dial PRX 40mm is the ultimate Go Anywhere, Do Anything watch. The 70s integrated bracelet design is iconic and super comfortable.
The texture on the black dial is incredibly rich. The Powermatic 80 movement runs like a dream. Feels like a watch that costs $5k.
Because the first link of the bracelet doesn't articulate fully, it wears closer to a 42mm. Keep that in mind. Still a solid 4 stars.
Got this for his birthday and he hasn't worn anything else since. It looks great dressed up with a suit or casual with jeans.
The hype around the PRX is 100% justified. The finishing on the case and the light play on the bracelet is completely unmatched for the price.
