Key takeaways
- Tissot PRX Powermatic 80 review from listing specs: 40mm black and silver dials, how the 35mm and green or ice blue versions differ, and a buying checklist.
The Tissot PRX line pairs a squared-off case and an integrated look with Swiss mechanical movements, and the listing we treat as the subject of this page is the Tissot PRX Swiss Powermatic 80, 40mm, black dial, men’s watch. This page is built from listing titles, manufacturer documentation in general terms and buyer feedback in general terms. Nobody on the team has worn or handled these watches, so any comment about comfort, accuracy or finish is framed as something to check rather than something observed.
The set contains six PRX listings that look similar but are not identical. Two titles name the Powermatic 80 movement outright, four say “Swiss Automatic” only, and one has a smaller 35mm case. Much of this page is about telling them apart, because that is where buyers get confused.

Who it suits and who should skip
These listings suit someone who wants a mechanical watch with a distinctive design and does not need smart features. A 40mm automatic suits an average adult wrist for everyday wear, and the dial colors in this set let you choose between a conservative black or silver and a more expressive green or ice blue. The 35mm listing is aimed at smaller wrists or buyers who like a compact case.
It is a weaker fit if you want fitness tracking, notifications or a watch you can drop in a drawer for three weeks and still find on time. A mechanical watch is wound by the motion of your wrist, so leaving it unworn will eventually let it stop. It also is not the best choice if you need dependable timekeeping to the second, since mechanical movements drift. And if you want a rugged tool watch, the titles do not state water resistance or case thickness, so you cannot judge ruggedness from them.
Anyone shopping mainly on price should note the premium tier here. The cost sits well above typical quartz watches, and the difference buys a mechanism, a design and a brand name, not extra features.
What the title does and does not tell you
Tissot PRX Swiss Powermatic 80, 40mm, black dial (the subject listing)
The title gives you five things: the brand and PRX line, Swiss origin, the Powermatic 80 name, a 40mm case size and a black dial, plus a men’s designation. Powermatic 80 is a movement name, and the listing is the clearest match for this keyword in the set.
The title does not give the power reserve, which you should look up in the manufacturer’s specification. It does not state water resistance, case thickness, lug-to-lug length, crystal type, bracelet width, strap or bracelet material, clasp type or whether there is a display back. It does not say whether the watch includes a warranty card. And it does not confirm the seller, which matters more with watches than with most products.
Pros
- The movement name is stated in the title
- Black dial is easy to match with other clothes
- 40mm is a common, versatile size
Cons
- Premium tier within this set
- Water resistance, thickness and power reserve are not in the title
- Mechanical watches need servicing over the years
Check the listing for: reference number, water resistance, bracelet or strap, warranty terms, and the seller’s return window.
Design, movement and everyday use
Design is the main reason people look at the PRX line. The titles tell you the dial color and the diameter, but nothing about finish, the shape of the bracelet links or how the case sits on the wrist. Look at the listing photos, and if you can, compare with a watch of the same size in a shop.
On the movement side, a Powermatic 80 listing is an automatic movement, wound by motion. General knowledge about automatics applies: they keep running while you wear them, they will stop if left unworn long enough, and you reset the time and date after a stop. The accuracy of an individual watch can vary. Treat any number you read online as a planning guess, not a promise, and look for the manufacturer’s stated tolerance.
For daily use, the title does not mention smart features, so assume none. There is no step counter, no phone link and no battery to replace in the way you would with a quartz watch. Water resistance is a number you must read from the listing, and any rating should be treated as a lab-style rating, not permission to swim without checking the crown is fully closed and the manufacturer’s instructions.
Build quality is also something the title cannot show. Buyer feedback in the listing may mention bracelet adjustment, clasp feel and the dial under light, but treat single comments with caution and read several.
Questions to ask before buying
- Which exact reference number is this, and does the manufacturer’s page confirm the movement?
- What are the stated water resistance and power reserve?
- Is it a bracelet or strap, and can your wrist size be fitted?
- Is the seller authorized, and does the manufacturer warranty apply?
- What is the return window if the size or color is wrong?
- How and where would you get the watch serviced later, and what might that cost?
Alternatives from the same set
All five other listings are PRX watches, so the choice is mostly about dial color, size and which titles confirm the Powermatic 80 name.
Tissot PRX Powermatic 80 Automatic, 40mm, silver dial
This listing is the second one to name the Powermatic 80 outright, and it adds the word “Automatic”. It is the same 40mm size as the subject with a silver dial, which looks lighter and a touch dressier. It sits in the same premium tier. If you prefer a brighter dial and want a movement named in the title, it is the closest sibling.
Pros
- Powermatic 80 named
- Light dial suits many outfits
Cons
- Same premium tier as the subject
- Light dials can show marks and glare in some light
Tissot PRX Swiss Automatic, 40mm, ice blue dial
The title says “Swiss Automatic” and does not name the Powermatic 80. The PRX family has had several versions, so the title alone does not prove the movement. The ice blue dial is the draw: it adds color without going to a saturated shade. Ask the seller to confirm the movement and reference number before buying.
Pros
- Distinctive dial color
- 40mm size, same as the subject
Cons
- Movement not named in the title
- Colored dials may not suit every style
Tissot PRX Swiss Automatic, 40mm, green dial
Another “Swiss Automatic” title without a movement name, this one with a green dial. It has the same case size and tier as the others, so the choice is a matter of taste. Green is more eye-catching than black or silver and can look different in daylight and indoors. Verify the movement name with the seller as you would with any listing that does not state it.
Pros
- Bold, distinctive color
- Same size as the subject
Cons
- Movement not stated in the title
- Color may feel limiting to some wardrobes
Tissot PRX Swiss Automatic, 40mm, black dial
This second black-dial listing looks similar to the subject on paper, but its title omits the Powermatic 80 name. It may be the same watch described less fully, a different reference or a different movement. Do not assume. Compare the reference numbers on both product pages, check the photos and ask the seller. If they match, you could use the price difference between sellers as the tie-breaker.
Pros
- Same black dial and 40mm size
- May be an alternate seller for the same watch
Cons
- Title is less specific than the subject listing
- Near-duplicate, which invites confusion
Tissot PRX Swiss Automatic, 35mm, ice blue dial
The only smaller case in the set, at 35mm, with an ice blue dial and no gender stated in the title. It sits in the mid-range tier, the lowest in this set, and the gap is small. It suits smaller wrists or anyone who prefers a compact watch. The title does not give thickness or lug length, so the size on the wrist may differ from what the diameter suggests. Check the return policy in case the fit disappoints.
Pros
- Compact size for smaller wrists
- Lowest tier in the set
Cons
- Movement not named in the title
- May look small on larger wrists
Choosing between dial colors and sizes
With a near-identical case shape across the set, the dial is the main variable. Black is the safest: it reads clearly, works with most clothes and tends to hide small marks. Silver is lighter and a little more formal. Ice blue and green are the expressive options, and their look can shift between daylight and indoor lighting, so check several listing photos rather than one hero image. If you are unsure, pick the color you would be happy to see every day for years, not the one that looks best in a single photo.
Size is the second variable. A 40mm case is a common middle ground, while 35mm will look compact on most adult wrists. Diameter alone is incomplete, because a short lug-to-lug length can make a larger case wear smaller and a thick case can catch on a sleeve. Measure your wrist, compare against the manufacturer’s dimensions and keep the return policy in mind.
What buyer feedback can and cannot tell you
The listing pages carry buyer reviews, and they are useful in a limited way. Repeated comments about bracelet adjustment, clasp feel or how the dial looks in light are worth noting. A single complaint is not a pattern. Be careful with feedback that mixes up different versions, since the PRX name covers several, and with comments about the seller or shipping, which describe the transaction rather than the watch. This page does not quote or count any reviews.
Care and ownership
Owning an automatic watch is a little different from owning a quartz one. Wear it regularly to keep it running, or set the time and date again after it stops. Keep it away from strong magnets such as speaker magnets and some bag clasps, which can disturb a mechanical movement. Rinse and dry the bracelet if it gets dirty, and follow the manufacturer’s instructions on water exposure. Plan for a service every few years, because the oils inside a movement age, and ask the seller or the manufacturer where service is handled in your region and roughly what it costs.
Price and value
Within this set the price tiers are close, so the value question is less about which listing is cheapest and more about what you are paying for. You pay for a Swiss mechanical movement, the case and bracelet design, and the manufacturer’s warranty if it applies. You do not pay for smart features. A fair comparison is with other entry-level Swiss automatics from other makers, whose titles you should read as carefully as these. Because the listings look alike, spend your effort confirming the exact reference, the seller and the warranty.
Buying checklist with a worked example
- Match the reference number on the listing to the manufacturer’s page.
- Confirm the movement name, power reserve and water resistance.
- Check bracelet or strap details and whether the size can be adjusted.
- Check the seller, warranty paperwork and return window.
- Decide how you will keep it running: daily wear or a winder.
- Plan for periodic servicing.
| Spec concept | What to look for | Why |
|---|---|---|
| Movement | Named movement and reference number | Several PRX versions look alike |
| Case size | Diameter, thickness, lug-to-lug | Fit depends on all three |
| Water resistance | Stated rating and crown type | Not in the titles |
| Seller and warranty | Authorized seller, warranty card | Protects you if there is a fault |
Worked example (estimates, with assumptions): suppose a mechanical watch gains 5 seconds a day, which is an assumption for illustration, not a statement about this model. Over 30 days that is 150 seconds, or two and a half minutes. If you set it monthly, the largest error you would ever see is about two and a half minutes. If a stated tolerance were 10 seconds a day, the worst case would double. Decide whether that suits you. If you wear it five days a week, it keeps running; if you rotate several watches, expect to reset it more often after a stop.
Verdict
For the keyword, the black-dial Powermatic 80 listing is the clearest match, and the silver-dial listing is its closest sibling. The ice blue, green and second black-dial listings may be fine watches, but their titles do not name the movement, so confirm it before paying. The 35mm listing is the one for smaller wrists. Whichever you choose, verify the reference number, the seller and the warranty, and remember that you are buying a mechanical watch with the strengths and quirks that implies.

Frequently asked questions
Is the Tissot PRX Powermatic 80 a good first automatic watch?
It is a reasonable candidate if you want a Swiss automatic with a modern integrated-bracelet look and you are comfortable with a mechanical watch’s trade-offs. The listings state 40mm cases, Swiss origin and several dial colors. They do not state water resistance, power reserve or thickness, so confirm those on the product page. A mechanical watch also needs occasional winding by wearing and periodic servicing.
How accurate is an automatic watch like this?
Mechanical watches are not as precise as quartz ones, and the exact rate depends on the individual watch, how it is worn and its position at rest. A drift of a few seconds a day is a common planning assumption, not a promise for this model. If perfect timekeeping matters more than the mechanism itself, a quartz or smartwatch is the more practical choice, and the manufacturer’s stated tolerance is the number to look for.
What is the difference between the Powermatic 80 listings and the “Swiss Automatic” ones?
Two titles name the Powermatic 80 explicitly. The other four say only Swiss Automatic, so the titles do not confirm that the same movement sits inside. The PRX name covers several versions, so verify the exact reference number and movement name on the product page or with the seller, and ask for the manufacturer’s specification sheet before you rely on any assumption about performance.
Does the 35mm Ice Blue PRX wear differently from the 40mm models?
A 35mm case is five millimeters smaller across than a 40mm one, which is noticeable on the wrist and often suits smaller wrists or people who like a more compact watch. The title does not give lug-to-lug length or thickness, and those matter as much as diameter. If you can, try a similar size in person, and check the return policy for a size mismatch.
Where should I buy to avoid problems?
Buy from the manufacturer or an authorized retailer, and read the listing for who ships and sells the watch. Ask whether the manufacturer warranty applies, whether a warranty card and box are included, and what the return window is. Very low prices, vague seller details or missing serial information are reasons to slow down. Keep the receipt and warranty paperwork in case you need service.
Can I wear a PRX in the shower or while swimming?
The titles do not state a water resistance rating, so do not assume. Look up the rating in the manufacturer’s documentation, and follow its instructions about the crown, hot water and soap. Ratings describe lab conditions and gaskets can age, so many owners avoid hot showers even with a capable watch. If a rating is not given or you are unsure, keep the watch dry and ask the seller or the manufacturer.
