Tissot PRX Powermatic 80 Review in 2026

Last updated 31 October 2026

This Tissot PRX Powermatic 80 review focuses on the blue 35 mm reference T1372071104100. The small case and steel bracelet are the reasons to start here. The larger automatic and the quartz PRX have their own dimensions. This model's figures should not be applied across the range.

Tissot PRX Automatic T1372071104100

Our verdict:

Smaller PRX automatic

Choose it for the smaller PRX case and spring-powered movement, but check the bracelet reach and accept setting after a long rest.

Keep in mind: The smaller case is not a fit promise; the bracelet can extend beyond the quoted case dimensions.

How we picked the Tissot PRX Powermatic 80 review reference

This version puts a self-winding movement in the smaller PRX case. Start here if you like the bracelet shape but find a larger watch too broad. The verdict rests on the maker's facts and the way you will use the watch. No wear or rate test is claimed.

It does not rest on a promise that every small wrist will suit the case. A smaller diameter helps narrow a search, but bracelet shape can still change how the watch sits. The first check is the whole case and bracelet across your wrist, rather than the number on the model name alone.

The Tissot US page is the source for the model facts below. Its strap list helps you check which parts attach. A seller's picture of another dial or size cannot prove an exact match.

T1372071104100 case and bracelet dimensions

Tissot lists a 35 mm case width and 10.93 mm thickness. It has a steel case and a sapphire crystal. Use those facts to compare PRX sizes. They come from the maker. No sample was measured here.

Do not read the quoted case length as the full reach of the bracelet. The first links can extend the part that will not bend around your wrist. A case dimension alone cannot tell you that span. If you cannot try the watch, ask for a useful measurement of the exact version rather than guessing from a product photo.

Our PRX sizing worksheet keeps case size apart from the full span you need to check. Use your own measurement where the maker does not give one. Unknown is a better answer than a made-up fit range.

The bracelet is steel and uses a butterfly clasp with push-buttons. It also has a quick-release system. Check the correct PRX size and attachment before ordering another band. A straight strap of a common width is not automatically a replacement for this shaped connection.

What the Powermatic 80 reserve means

Tissot specifies an 80-hour reserve. That is the maker's stated maximum stored-power figure, not a result from this review. The energy available after a short spell on your wrist can be different from a fully wound movement's reserve.

Think about your normal week. If you leave an automatic off for long enough, you may need to set it before you put it on again. If you rotate watches, decide whether that step bothers you. A quoted reserve can help compare specifications, but it cannot choose an ownership routine for you.

The watch winds through a rotor as it moves. It still stores power in a spring. Our automatic-watch guide shows how that works. Start there if this would be your first watch of this type.

Follow the matching Tissot instructions when winding or setting the date. Do not borrow a crown routine from a different caliber. A movement name in a retailer headline is not enough to settle every operating detail.

Blue dial, date and the limits of a photo

This reference has a blue dial with a textured pattern and a date display. That gives it a different appearance from the smooth dial of the quartz PRX. The pattern is a style choice, rather than evidence of a stronger or more accurate watch.

Look at the hand shapes and minute marks as well as the dial color. A studio image can show texture and finish, but it cannot prove that you will find the watch easy to read in your room. Check it in ordinary light if you have the chance.

The maker names luminous material on the hands. This review gives no glow-duration result. It also gives no daily-rate result, impact score or measured reserve. Those claims would need defined tests and a watch to test.

Water use and a steel bracelet

The case has a 10-bar water-resistance specification. Follow Tissot's instructions for the exact watch and its current condition. That number is not a safe depth to calculate for a dive, and the bracelet style does not turn the PRX into a diver's watch.

A watch that has suffered damage or needs service deserves a fresh check before wet use. Keep crown operation out of water. When choosing a watch for a water activity, start with the manual's limits rather than a general style label.

Quartz or automatic PRX?

Choose this automatic if the winding mechanism is part of what you want. Choose the quartz PRX if you prefer a battery-powered routine. Neither choice needs a story about one movement type being the right answer for everyone.

Case size is a separate choice from movement. The quartz PRX T1374101104100 has a larger 40 mm case. If you want to compare movements alone, keep the case size and strap choice consistent when you can. A difference in fit may matter more to you than the mechanism inside.

Before buying, read the seller's return terms and confirm the exact reference. If the clasp or bracelet cannot be adjusted to suit you, a strong movement specification will not solve that problem. Keep the documents that explain the supplied warranty and who handles a repair.

A practical fit check before you keep it

Check the watch while your hand is relaxed, then bend your wrist as you would at a desk. Look at whether the case rocks and whether the first links reach too far across the top. A tighter bracelet is not always the answer to a case shape that does not suit you.

Make that check while the seller's return terms still allow it. Read those terms first, since removing links or wearing a watch can affect a return. The fit check is a buying task for your own wrist. It is not a wear test claimed by this review.

Strengths and drawbacks

Strengths

• The 35 mm case offers the smaller PRX automatic design.
• The steel bracelet suits someone who wants that part of the PRX style.

Drawbacks

• Case width does not establish the bracelet's full rigid span.
• The automatic movement can need setting after a long rest.

Verdict on the Tissot PRX Powermatic 80 review

The 35 mm T1372071104100 is a clear starting point for a buyer who wants a smaller PRX with an automatic movement. Its stated reserve is useful context, but the main decision is whether you want that movement and whether the whole bracelet assembly sits well on your wrist.

Choose it after checking the fit and accepting the setting routine. If either remains uncertain, use the sizing worksheet and movement comparison before making the purchase. This Tissot PRX Powermatic 80 review supports a reference-level choice, rather than a claim that one size suits every wearer.
