Works great with suits
Fits my wrist comfortably and slides right under a French cuff. The dark green dial adds a bit of personality to grey and navy office suits without looking loud across a conference table.
The watch
Built around a green 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. We place it at Hour III (Integrated Sport) of the Boardroom season, for smart-casual offices and city weekends.
The green PRX is the expressive one. A rich sunburst green dial glows emerald in daylight and turns nearly forest-dark indoors, set against the slim tonneau case and integrated steel bracelet that made this design an instant modern classic.
It is driven by the Swiss-made Powermatic 80, a self-winding automatic that draws energy from your wrist and stores around 80 hours of reserve. The exhibition caseback puts the movement on display.
At 40mm the case stays slim and comfortable, sliding under a cuff yet reading unmistakably as a sports watch. Sapphire crystal resists scratches and 100m (10 ATM) of water resistance covers swimming and daily wear.
For the buyer who already owns the safe colours and wants something with character. Green is the standout of the PRX range, quietly confident and endlessly complimented.
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 green 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
Fits my wrist comfortably and slides right under a French cuff. The dark green dial adds a bit of personality to grey and navy office suits without looking loud across a conference table.
Wore this out to dinner and the green waffle dial really comes alive in afternoon sunlight. Only minor complaint is the butterfly clasp doesn't have micro-adjust holes, so even with the half-links it sits slightly snug in coastal humidity.
For an entry-level Swiss integrated sports watch, the T137.407.11.091.00 nails the proportions on my wrist. The emerald-to-forest waffle dial has crisp stamping around the applied indices and framed date window. Inside, the Powermatic 80 with its Nivachron balance spring shrugs off magnetic fields and has run at +1.5 sec/day since day one.
At 10.9mm thick with 100m water resistance and a sapphire crystal, this covers everything I need during the school week. The butterfly clasp locks solidly and the silver hands contrast well against the dark green dial.
The brushing across the integrated bracelet links lines up cleanly with the 40mm barrel case. Crown action has a positive click at both the date and time-setting detents, and timekeeping has stayed within +2 seconds per day over two weeks.
Fitted the stock steel bracelet to my wrist right out of the box without removing any links. I also grabbed a notched green rubber strap made for the PRX lug notch, and the quick-release pins let me swap between steel and rubber in thirty seconds.
Checked the Powermatic 80 over a full 72-hour rest off the wrist and it kept ticking right on schedule. The 40mm brushed steel case has crisp transitions, the sapphire crystal is flat and clear, and the bracelet links articulate smoothly without pulling hair.
The green waffle dial is dark enough indoors to pass as charcoal during client meetings, then turns a rich forest green when you step outside. Clears dress shirt cuffs easily on my wrist. The date window is a little small to read without my reading glasses.
Thanks for the feedback, Alan! That forest green waffle dial really does change character depending on the light.
