Tissot PRX

Is the Tissot PRX worth it?

As a watch, clearly: thin, sapphire, 80 hours, 100m and a published service price. As a watch to keep for decades, the bracelet is the question.

By Sawyer V. · Published

The short answer

Yes, as a watch — 10.93mm thick, sapphire, 100m, an 80-hour Powermatic 80 and a published $210 US service price. As a watch to keep for decades, the integrated bracelet is a real constraint: no aftermarket strap fits the 12mm fitting, so you depend on Tissot for the part most certain to wear.

The PRX is the most talked-about watch in its price band, and the most copied. Tissot's own brand page on this site already gives the short answer: as a watch, very much so; as a watch to keep for decades, the bracelet is the constraint. This page is the long version.

What the PRX gets right

  • Sapphire and 100m — the two specifications most integrated-bracelet watches at this price skip.
  • 80 hours of reserve from the Powermatic 80, so a watch left off at the weekend is still running on Monday.
  • 10.93mm thick in both sizes, which is thin for a 100m automatic.
  • A published service price — $210 in the US with 24 months of warranty on the work, which almost nobody at this level offers.

The catch

The bracelet is integrated into the case. The fitting is 12mm on the 40mm and 11mm on the 35mm — not strap sizes. You cannot put the PRX on a leather strap, a NATO or a rubber strap from anyone but Tissot, and when the bracelet eventually wears — bracelets are the part of a watch most certain to — the only replacement is Tissot's. That is why the Keep Score gives it 0.2 out of 1 for strap standard.

How we picked

We have not worn these watches. What follows is what we checked instead, on documents you can open yourself — the same criteria, in the same order, on every roundup on this site. The full method is on the methodology page.

  1. 01The watch

    Sapphire, 100m, 80 hours, 10.93mm — on paper, one of the best specification sheets in its band.

  2. 02The paperwork

    Tissot publishes $210 for a complete US service with 24 months on the work, and states a two-year warranty.

  3. 03The bracelet

    Integrated, with a 12mm fitting on the 40mm and 11mm on the 35mm. Neither is a strap size.

  4. 04The sizes

    40mm and 35mm, both 10.93mm thick.

The original size, and the one the design was drawn for. 40mm reads as a moderate sports watch because the bracelet flows straight from the case.

Everything above applies — including the 12mm bracelet fitting.

Tissot publishes a US complete-service price of $210 for a mechanical two-or-three-hand watch, which makes this the most predictable Swiss automatic here to own. The 12mm lug width is not a strap size — the bracelet is part of the case.

The 35mm keeps every specification of the 40mm — sapphire, 100m, the Powermatic 80 — in a case that suits a smaller wrist or a dressier look.

Its bracelet fitting is 11mm, with the same long-term dependency on Tissot.

An 80-hour Swiss automatic at 35mm with sapphire and 100m, backed by Tissot's published $210 service price. The integrated bracelet is the long-term trade — an 11mm fitting is not a strap size, so you keep the bracelet the watch came with or you keep nothing.

Buyers put off by the PRX's bracelet often move sideways to the Le Locle, which has standard 19mm lugs, sapphire and an 80-hour Powermatic 80 with a Nivachron hairspring.

It is rated 30m. Swapping a bracelet you can't replace for a case that can't meet water is not an improvement.

If you want Tissot's service price with standard lugs, the [Gentleman Open Heart](/brands/tissot-vs-seiko) is 100m. If you want the PRX's look on a standard strap, no Tissot here offers it.

Under 10mm thick with 80 hours of reserve is the combination that makes a dress watch practical — put it down on Friday and it is still running Monday. 30m means keep it off in the shower.

If the bracelet is a deal-breaker

  • Same money, standard lugs, Swiss: the Hamilton Khaki Field — 38mm, sapphire, 80 hours, 20mm lugs.
  • Same money, standard lugs, better paperwork: the Seiko Alpinist SPB317 — sapphire, 70 hours, a published $296 overhaul.
  • Tissot with standard lugs: the Gentleman Open Heart — 100m, 80 hours, the same $210 service, on 21mm lugs.

Questions people actually ask

Is the Tissot PRX worth the money?

As a watch, yes — sapphire, 100m, 80 hours, 10.93mm thick and a published $210 US service price. As a watch to keep for decades, the integrated bracelet means you depend on Tissot for the part most likely to wear.

Can you put a strap on a Tissot PRX?

Not a standard one. The bracelet fitting is 12mm on the 40mm and 11mm on the 35mm, which are not strap sizes. Only Tissot's own straps and bracelets fit.

PRX 35mm or 40mm?

Specification-wise they are identical — sapphire, 100m, 80 hours, 10.93mm thick. Choose on wrist size; the 35mm suits smaller wrists and dressier use.

How much does it cost to service a Tissot PRX?

Tissot publishes $210 for a complete service of a mechanical two- or three-hand watch in the US, with 24 months of warranty on the work.
