Tissot PRX 40mm Powermatic 80 — Blue Dial, Steel Bracelet
The watch
Tissot PRX 40mm Powermatic 80: a blue-dial integrated-bracelet watch in a 40mm stainless steel case, driven by a Powermatic 80 automatic movement. Expect 100m water resistance and a sapphire crystal. We place it at Hour III (Integrated Sport) of the Boardroom season, for anyone who wants one watch for work and leisure.
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.
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.
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.
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.
New, boxed and warrantied — ships within the US.
Good to know
It runs on a Powermatic 80 automatic movement. It winds itself from the motion of your wrist, so there is no battery to replace.
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.
The case measures 40mm — a versatile size that suits most wrists (roughly 15.5-19 cm / 6.1-7.5 in). Our watch size guide (/pages/watch-size-guide) explains how to measure your wrist.
It has a blue dial, under a sapphire crystal.
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.
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.
On the ChronoSeasons dial it sits at Hour III — Integrated Sport, part of the Boardroom season, and suits the office-to-dinner day and smart-casual weekends.
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.
From the journal
Owners say
Most of my collection is 42mm aviation chronographs and GMTs, so I wanted a clean three-hander with a 1970s cockpit-instrument vibe for casual Fridays. The angular tonneau case and blue grid dial remind me of vintage flight gauges, and the 80-hour reserve is super reliable.
I spend a lot of summer weekends out on Long Island Sound, so having 100m water resistance on a sleek steel watch is a huge plus. It handles spray and swimming off the boat without issue, and the blue waffle dial is easy to read in bright sun.
The blue waffle dial pairs nicely with navy and grey slacks at the pharmacy and in administrative meetings. It slides under a buttoned cuff without catching, though the date numerals at 3 o'clock are a little small without my reading glasses.
Fast shipping to Tucson. Took out four links and it fits my wrist great.
Case brushing and link articulation are very consistent. The twin-trigger butterfly clasp locks flush, and the 100m water resistance rating is practical for daily wear. Only minor note is the Super-LumiNova on the thin hands is decent for a couple hours after dark, not an all-night torch.
On my 6.5-inch wrist the 40mm PRX wears right at the edge of my comfort zone due to the flaring end-links, though the slim 10.9mm thickness keeps it seated flat. The stamped blue waffle dial and applied baton indices catch light at every angle, and the Nivachron hairspring in the Powermatic 80 caliber has kept time within +2 seconds per day around my laptop and monitors.
I held off on buying the blue PRX 40mm for half a year because I wasn't sure if the bracelet would feel flimsy. Once I got it on my wrist, the solid links, sharp case brushing, and sapphire crystal completely won me over.
