Tissot PRX 40mm Powermatic 80 — Black Dial, Steel Bracelet
The watch
Built around a black dial, the Tissot PRX 40mm Powermatic 80 pairs a 40mm case with a Powermatic 80 automatic movement. Expect 100m water resistance and a sapphire crystal. On the ChronoSeasons dial it sits at Hour III — Integrated Sport, part of the Boardroom season — and suits the office-to-dinner day.
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.
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.
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.
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.
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 black 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.

Owners say
Wasn't sure how a sub-twelve-hundred-dollar Swiss sport watch would feel next to my older pieces, so I was pleasantly surprised when I unboxed it. The weight of the brushed steel bracelet and the crispness of the black dial are spot on.
One underrated feature on the PRX is the quick-release spring bars built right into the integrated steel bracelet. I sized the steel links for my wrist, and also picked up a notched black FKM rubber PRX strap that swaps in without any tools.
I'm usually skeptical of integrated bracelets under two grand because the links can feel stamped or pinchy. The single-piece links and hidden butterfly clasp on this PRX feel remarkably well finished, and the sapphire glass is crystal clear.
Wore this through three days of depositions and out to dinner afterward. The black waffle dial is understated enough for a dark suit, the thin profile clears my shirt cuffs easily, and the 80-hour reserve means it's still ticking Monday morning.
Bought this for my fiance as an engagement gift because he is super particular about watch design and wanted an integrated steel bracelet. He sized it that same evening and has worn it to work and dinner every single day since.
Because of the fixed first center link on the integrated bracelet, the effective lug-to-lug on the 40mm PRX is closer to 51mm, which sits flat across my 7.5-inch wrist. The vertical brushing on the tonneau case contrasts sharply with the polished bezel, and the embossed black waffle dial gives it a distinct mechanical character over the quartz version. My Powermatic 80 is averaging +1 second per day.
Great Monday-through-Friday watch for the office. The slim 10.9mm case slides under a button-down cuff without snagging, and the brushed integrated bracelet looks sharp with a sport coat. The framed date window at 3 o'clock is a little small without my reading glasses.
I like wearing larger menswear-style watches on my wrist, and the 40mm black PRX has a bold 1970s architectural look at the design studio. The bracelet drapes well once sized. Only downside was the courier delaying delivery by two days.
The 40mm tonneau case and integrated steel bracelet are machined with very little play between the links. The black tapisserie dial is legible at any angle and the Powermatic 80 movement holds +2 seconds a day. Though the shipping carrier delayed the box by two days.
I had seen the PRX all over watch forums for months and wondered if the integrated bracelet was mostly internet hype. After wearing the black waffle-dial 40mm for two weeks, the brushed steel links and bevels really do feel solid and catch the light nicely on my wrist.
