PRX vs Tsuyosa

Tissot PRX vs Citizen Tsuyosa

The two integrated-bracelet automatics everyone cross-shops. One gives you 80 hours and a published Swiss service price; the other gives you five years of warranty one tier down.

By Sawyer V. · Published

The short answer

The Tissot PRX for most buyers: an 80-hour Powermatic 80, 100m, a 10.93mm case and a published $210 US service. The Citizen Tsuyosa if the five-year warranty matters more: an in-house hacking 8210 behind sapphire, one tier down, but with 42 hours of reserve and 50m.

The PRX and the Tsuyosa are the two affordable integrated-bracelet automatics on this site, and they are cross-shopped constantly. Both have sapphire and a 40mm case, and both commit you to the bracelet they come on. Past that, they are built on different priorities.

The Tissot alternative with a conventional bracelet: sapphire, 100m and 80 hours, on a quick-release bracelet that swaps to a standard strap in seconds.

The open heart is a taste the PRX and Tsuyosa do not ask you to share, and the lug width is 21mm.

The quick-release bracelet is the detail worth paying for: this is one of the few Swiss automatics at this level you can re-strap in thirty seconds without a tool.

80 hours of reserve, 100m, sapphire and a 10.93mm case, with Tissot's published $210 complete service and 24 months on the work.

Two years of warranty, and a 12mm bracelet fitting no standard strap fits. The [full PRX verdict](/brands/is-the-tissot-prx-worth-it) covers it.

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 same movement, sapphire and 100m at 35mm, if the 40mm PRX or the Tsuyosa is too wide.

An 11mm bracelet fitting. [PRX 35 vs 40](/brands/tissot-prx-35-vs-40) compares the two sizes.

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.

An in-house hacking 8210 behind sapphire with Citizen's five-year warranty, in our under-$500 tier.

42 hours of reserve, 50m and a 9.1mm lug width — the bracelet is the watch — and Citizen publishes no service prices.

Sapphire and an in-house automatic for the money is genuinely rare. The catch is structural: Citizen lists the lug width as 9.1mm, which means the bracelet is the watch. When it wears out, no strap shop can help you.

The AK00 is the other sapphire automatic at the Tsuyosa's tier, with domed sapphire, a day-date and three years of warranty.

It is 14mm thick with a 50.5mm lug-to-lug — a big case where the PRX and Tsuyosa are sleek — and rated 50m. It is a different kind of watch, not a cheaper version of either.

Domed sapphire at this price is unusual and it is why this one is here. The 50.5mm lug-to-lug is not — that is a big watch, whatever the 42.5mm on the spec sheet suggests.

Which to buy

  • The PRX for the longer reserve, 100m, the thinner published case and a published service price.
  • The Tsuyosa for the five-year warranty and a lower tier, if 50m and 42 hours are enough.
  • Neither, if you want to change straps: both bracelets are integrated. The Tissot Gentleman is the alternative.

Each on its own: is the Tissot PRX worth it and is the Citizen Tsuyosa worth it.

Questions people actually ask

Is the Tissot PRX better than the Citizen Tsuyosa?

For most buyers, yes: 80 hours against 42, 100m against 50m, a published 10.93mm case and a published $210 service. The Tsuyosa has the longer warranty — five years against two.

Can you put a strap on a PRX or a Tsuyosa?

Not a standard one. The PRX uses a 12mm integrated fitting and Citizen lists a 9.1mm lug width for the Tsuyosa; both are built around their bracelets.

Which is thinner?

Tissot publishes 10.93mm for the PRX. Citizen does not publish the Tsuyosa's thickness.

Does the Tsuyosa hack?

Yes. Citizen states hacking for the 8210.
