I keep opening the Tissot PRX Powermatic 80 the way some people refresh sneaker drops. Not because I need another steel watch. Because this one still looks like 1978 without dressing like a costume. Tonneau case. Integrated bracelet. That waffle dial. Swiss automatic. It is the sports-dress shape a lot of us actually mean when we type “PRX.”
The version I keep coming back to on Amazon is ice-blue. Pale in indoor light. Colder in sun. Not navy. Not silver. If you already like the PRX silhouette and you want a dial with a little weather in it, this is the one I would click first.
I shopped it the way I shop most watches now: Amazon US, sold by Amazon.com, model number in the cart so I do not grab a quartz cousin by accident. The reference I matched at checkout is T1374071135100.
Price And Rating When I Checked
When I checked in early September, the new Amazon.com offer was $850.00. The page showed 4.8 out of 5 from 100 ratings. In stock. Sold by Amazon.com. A used resale offer sat nearby around $799. I would still start with the new Amazon.com box unless you are comfortable with a used automatic and its return path. Other stores may list a different price. I only trust the figure on the day I buy.

How It Looks And Wears
This is taste, not a lab report. I like ice-blue on steel more than I like silver on steel. Silver can look like every other office watch. Ice-blue still reads as a PRX, but it does not disappear against a white shirt. Under lamps it is almost grey-blue. Outside it can go glacier. The waffle texture is the whole point of this dial. If you wanted a flat sunburst, this is the wrong colorway.
The case is 40 mm across and about 10.93 mm thick, in 316L steel, tonneau rather than a round puck. Short integrated lugs. No extra horn sticking past the bracelet. That is why it wears smaller than a lot of 40 mm divers on paper. It is not a 7 mm dress sliver. It is not a tool watch either. In my taste, that in-between is the job: jeans on Saturday, a jacket on Monday, same watch.
Date at 3, framed. Applied indices. Sapphire on the front. About 140 g as listed, which is steel-bracelet weight, not a titanium feather. If you hate mass on the wrist, you will feel this one. I do not mind that kind of weight when the case is this thin for a sports watch. A 1970s integrated sports watch with manners. That is the lane I want it in.
The Movement In Plain English
Powermatic 80 is Tissot’s Swiss automatic in this watch. Self-winding. Up to 80 hours of reserve, which in real life means you can take it off Friday night and it should still be running Monday morning if it was fully wound. Leave it in a drawer for four days and you will reset the time and date. That is normal for an automatic. It is not a quartz “set it and forget it” deal.
Tissot’s listing copy mentions a Nivachron hairspring. I treat that as maker language, not a lab certificate I personally ran. I am not claiming COSC, a specific seconds-per-day rate, or magic anti-magnetism. Wear it. Wind it if it stops. Service it like any mechanical watch when the time comes. If you rotate five watches and this one sits for a week, you will still be setting it. Buy quartz if that bothers you.
Bracelet, Sizing, And Water
Steel bracelet. Butterfly clasp with push-buttons. Quick-release, so Tissot’s own PRX straps can come off without a fight. Do not buy a generic 20 mm or 22 mm leather strap and expect it to fit. This is an integrated bracelet. If you ever swap to rubber or leather, get a strap cut for the PRX, not a standard spring-bar band from a parts bin.
You will almost certainly size the bracelet. That is a first-evening job with most steel sports watches, not a scandal. Links, a pin tool, or a jeweler. If your wrist is on the large side, confirm the return window before you assume extra links will appear like a gift.
Water resistance is listed at 10 bar / 100 m. In the language Amazon uses, that is swimming and showering, not scuba. Rinse after salt or chlorine. Dry the clasp. Do not work the crown in the water. I treat 100 m here as rain, a sink, and a pool — not a dive computer.
Warranty, as stated, is a 2-year international warranty. Keep the invoice. Buy from Amazon.com on the offer I saw, not a random third-party cart with a price that looks too lucky.
Who It Is For, And Who Should Skip It
I would buy this if I wanted a Swiss automatic with that 1970s integrated look, I preferred ice-blue to silver, and I was fine spending about $850 on Amazon for a watch I will actually wear. The 4.8 average from 100 ratings is a decent sample of people who already own one. It is not proof you will love the color.
I would skip it if I needed a confirmed silver dial and ice-blue felt like a compromise. Or if I wanted something under 9 mm for a dress shirt cuff. Or if I needed a certified dive watch. Or if I was not willing to size a bracelet. Also skip it if the only offer left is a third-party seller you cannot warranty. Match the model number. Quartz PRX watches and gold-tone specials are different products.
If your taste runs louder — green, a gradient, a bezel — this ice-blue will feel quiet. That is a feature for me. Color is the whole argument on this reference.
Bottom Line
This is the ice-blue Tissot PRX Powermatic 80 I keep shopping: 40 mm, waffle dial, Swiss automatic with that long reserve, steel bracelet, 100 m for swimming and showers. When I checked in early September it was $850 new, 4.8 from 100 ratings, in stock from Amazon.com. I like the color. I like the thickness. I like that it does not pretend to be a diver or a dress-only sliver.
If that is your taste too, look at the live listing, confirm the model number, and re-check the price the day you buy.
