Timex Expedition Pioneer Automatic 41mm TW2Y87400

Pioneer vs Tsuyosa

Timex Expedition Pioneer Automatic vs Citizen Tsuyosa

Both are sapphire-fronted automatics around the same money. One of them you can swim in and re-strap forever. The other names its caliber and covers it for five years.

By Sawyer V. · Published

The short answer

Buy the Pioneer. Sapphire, 200m and a standard 20mm lug width mean you can swim in it and re-strap it forever, and it scores 8.0 against the Tsuyosa's 7.7. Buy the Tsuyosa instead only if the five-year warranty and the named hacking caliber matter more to you than water resistance — and only once you accept that its 9.1mm integrated bracelet can never be replaced.

Full write-up and the measured specifications are further down this page.

This is the single most-asked question on this site in the exact words a buyer uses: which of these two is the better buy at today's prices. They invite the comparison — both are steel automatics with sapphire crystals, both land in the same few hundred dollars, and both are sold by brands you have heard of.

They are not, however, the same kind of object. The Pioneer is a field watch rated for swimming with ordinary 20mm lugs. The Tsuyosa is an integrated-bracelet sports-dress watch rated for rain, with a bracelet that is structurally part of the watch. Choosing between them is mostly choosing which of those two things you want.

This site scores watches on six published specifications, and two of them — strap standardization and whether the maker publishes a service price — are about year eight rather than week one. On those, the two watches fail in opposite directions, which is why the gap between them is narrow.

On prices: every buy button on this page reads its figure from the live price layer and stamps the date it was checked, or else reads "Check price on Amazon". No price is written into this text. Service figures quoted here are the manufacturers' own published rates.

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. 01Water resistance

    200m with a screw-down crown against 50m. This is the largest single gap between them and the one most buyers underrate.

  2. 02Strap standardization

    20mm standard lugs against a 9.1mm integrated fitting. One takes any strap ever made; the other takes exactly one bracelet, made by Citizen.

  3. 03Is the caliber named

    Citizen states an 8210 automatic, hacking, 42 hours. Timex says "automatic" and nothing else — you cannot look up what an overhaul involves.

  4. 04Warranty term

    Five years against one. Citizen's excludes the power cell, case, bracelet and strap; Timex's excludes the crystal, strap, case and battery.

  5. 05What is identical

    Sapphire crystal, a stainless steel case, an automatic movement, and both on Amazon with a published price today.

200m with sapphire is the headline, and it is real. That is a watch you can swim in, shower in and stop thinking about, which at this money usually means giving up the sapphire or the automatic.

20mm lugs are the quiet reason it wins. A standard even lug width means every strap ever made fits it, now and in twenty years. The Tsuyosa's 9.1mm integrated fitting means the bracelet is the watch.

Timex does not publish the caliber. The product page says "automatic" and stops, so you cannot look up parts or what a rebuild costs before buying. The one-year warranty excludes the crystal, strap, case and battery, which is the thinnest cover of any watch on this page.

It is also the bigger watch: 48mm lug-to-lug and 14mm thick, against a 40mm Tsuyosa whose figures Citizen does not publish at all.

Sapphire and 200m for the money is real. What Timex does not publish is the caliber — which means you cannot look up what an overhaul costs before you buy, and that is exactly the number this site exists to check.

Citizen names the movement and Timex does not: an 8210 automatic that hacks, with 42 hours of reserve. For setting the watch accurately and for knowing what you own, that is a genuine advantage.

Five years of cover against one is the other real advantage, though Citizen's excludes the power cell, case, bracelet and strap.

The 9.1mm lug width is the problem, and it is permanent. This is an integrated bracelet, not a strap fitting — when it stretches or breaks, no strap shop on earth can help you, and the watch is finished as a wearable object. On a site about buying once, that is the single worst specification here.

50m is the other limit. Citizen rates it for splashes and rain, not swimming, and publishes neither the lug-to-lug nor the thickness for this reference.

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.

It is not on this page's question, and we list it because it beats both answers. Sapphire and 200m like the Pioneer, a named in-house caliber that hacks and hand-winds like the Tsuyosa, and 22mm standard lugs.

It scores 9.0 on the same six specifications, the highest figure on this site, against 8.0 and 7.7. Orient also states a three-year warranty, longer than Hamilton's or Tissot's.

12.8mm thick with a 46.8mm lug-to-lug makes it both thinner and shorter than the Pioneer. If you are spending this much on a steel automatic with sapphire, read our dive watches under $500 page before you commit to either watch above.

On paper this is the best value in the category and it is not close: sapphire and a hacking, hand-windable in-house caliber at a price where Seiko still fits Hardlex. Orient's three-year warranty is longer than Hamilton's or Tissot's.

The bracelet is the whole argument

A 9.1mm lug width is not a strap size. It is Citizen telling you that the bracelet and the case are one design, and that the only replacement is the one Citizen makes. While Citizen still makes it, that is a non-issue. The day it stops, the watch becomes an object you cannot wear.

The Pioneer's 20mm lugs are the opposite proposition. Twenty millimeters is the most common strap size in the world; a leather strap, a NATO, a rubber dive strap and a steel bracelet all fit, cost very little, and will still be sold decades from now. Our guide to watch straps covers why an even, standard lug width is worth more than most spec-sheet features, and quick-release straps covers changing them without tools.

200m versus 50m, in practice

50m means rain, hand-washing and a caught shower. It does not mean swimming, and Citizen does not claim it does. 200m with a screw-down crown means everything short of scuba, indefinitely, without thinking about it.

If the watch is going to be the only one you own, that difference decides more days than the movement does. Our water resistance guide sets out what each rating actually permits and why the number is not a depth.

The caliber Timex will not name

The Pioneer's real weakness is not a number on the spec sheet, it is an absence. Timex publishes no caliber, no power reserve and no service price, so before you buy you cannot find out what an overhaul costs or whether parts exist. Citizen at least names the 8210 and states 42 hours.

That is why the two watches finish 0.3 apart rather than further. The Pioneer wins on the specifications you use every day and loses on the one this site cares most about. Our cost of ownership guide shows what published service prices look like when a maker does provide them — Seiko's $176 for a 4R, Tissot's $210 for a complete mechanical service.

Which to buy

The Pioneer, unless you have a specific reason to want the Tsuyosa's warranty. It is the more useful watch on more days, and the 20mm lugs mean it can be made new again with a $30 strap long after the Tsuyosa's bracelet has become its retirement notice.

And if the real question is simply what the best steel automatic with sapphire is at this money, the answer on this site is neither of them — it is the Orient Kamasu, which does what both of these do and scores 9.0 doing it.

Questions people actually ask

Which is the better buy, the Timex Expedition Pioneer Automatic or the Citizen Tsuyosa?

The Pioneer, narrowly. It is rated 200m against the Tsuyosa's 50m and takes any 20mm strap, where the Tsuyosa's 9.1mm integrated bracelet can never be replaced. It scores 8.0 against 7.7 on our six published specifications. The Tsuyosa wins only on warranty term and on naming its caliber.

Can you replace the bracelet on a Citizen Tsuyosa?

Not with an ordinary strap. Citizen lists the lug width as 9.1mm because the bracelet is integrated into the case design, so the only replacement is Citizen's own. This is the main reason the watch loses to the Pioneer here.

Can you swim with the Timex Expedition Pioneer Automatic?

Yes. Timex rates it to 200m, which covers swimming, showering and snorkeling. The Tsuyosa's 50m rating covers rain and hand-washing only.

What movement is in the Timex Expedition Pioneer Automatic?

Timex does not say. The product page states only that it is automatic and publishes no caliber and no power reserve, which means you cannot check parts availability or service cost before buying. Citizen names the Tsuyosa's 8210 and states 42 hours.

Is there a better option than either at the same price?

The Orient Kamasu. It has sapphire and 200m like the Pioneer, a named in-house hacking automatic like the Tsuyosa, 22mm standard lugs and a three-year warranty, and it scores 9.0 against 8.0 and 7.7.
