Same brand, same five-year warranty, same price bracket — and you cannot have sapphire, 200m and a replaceable strap in one of them. This is the trade Citizen makes you pick.
Buy the Promaster BN0200 if the watch is for wearing: Super Titanium, 200m, a standard 22mm strap fitting and nothing to wind or service. Buy the Tsuyosa if you want sapphire and a mechanical movement in a dressier 40mm case, and accept that its 9.1mm integrated bracelet can never be replaced.

Keep Score
44mm Super Titanium, mineral, 200m, 22mm lugs, light-powered, five years.
200m with a screw-down case, in Super Titanium, on a movement that needs nothing done to it. That combination is the reason to buy a Citizen at all: you can swim in it, forget it in a drawer for two months, pick it up and it is running and correct.
The verdict first: buy the Citizen Promaster Diver BN0200 if the watch is going to be worn and used. Super Titanium, 200m, a screw-down case built for it, a standard 22mm strap fitting, and an Eco-Drive movement that never needs winding, a battery or a service appointment. Buy the Citizen Tsuyosa if you want a sapphire crystal and a mechanical movement in a 40mm dress-adjacent case — and you accept the one thing about it that cannot be undone.
These two turn up together on five pages of this site and almost nowhere else in the same sentence, because they are what a Citizen shortlist actually looks like once you stop reading brand pages. They cost within a bracket of each other, they carry the same five-year warranty, and they are opposite watches.
The trade Citizen makes you pick
Here is the finding, and it is uncomfortable for a brand whose whole argument is low-maintenance ownership: at this price, inside this brand, you cannot have sapphire, 200m and a replaceable strap at the same time.
The Promaster gives you 200m, Super Titanium and a 22mm standard fitting, and fits a mineral crystal to do it. The Tsuyosa gives you sapphire and a mechanical caliber, and takes away the water rating and the strap — Citizen lists the lug width as 9.1mm, which means the bracelet is part of the watch rather than something attached to it. Our Citizen brand page calls Eco-Drive the brand's strongest argument, and it is; this page is about what that argument costs on the two watches where it is actually offered.

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.
01Crystal
Sapphire against mineral. The Tsuyosa wins outright, and on a watch you keep this is the line that shows.
02Water resistance
200m against 50m, read from Citizen's own pages. This decides what the watch can actually be used for.
03Strap fitting
A standard, even 22mm against a 9.1mm integrated bracelet, which is not a strap size at all.
04What it asks of you
A light-powered movement needs nothing. A mechanical one needs wearing or winding, and can be rebuilt in exchange.
05Warranty and service
Five years on both, with identical exclusions, and Citizen publishes no service price for either. The usual tiebreaker on this site is a tie at zero.

Prices as of October 29, 2026. Amazon pricing changes without notice — the figure on the listing is the one that counts.
Keep Score is arithmetic, not opinion — six published specifications, weighted the same way on every page. The formula is on our methodology page, so you can re-run it yourself.
200m with a screw-down case, in Super Titanium, on a movement that needs nothing done to it. That combination is the reason to buy a Citizen at all: you can swim in it, forget it in a drawer for two months, pick it up and it is running and correct.
Super Titanium is Citizen's surface-hardened titanium, which answers the one real weakness of the metal — plain titanium is softer than steel and marks easily. It is also lighter than steel on a 44mm case, where weight is the thing that quietly retires a big watch.
The 22mm lug width is standard and even, so a strap in any material is a permanent, cheap option. That sounds minor beside a 200m rating and it is the single biggest practical difference between this watch and the Tsuyosa.
Two honest costs. The crystal is mineral, which collects scratches that cannot be polished out, and on a 44mm dial that is a large flat target you will eventually see marked. And an Eco-Drive module is replaced rather than rebuilt — when Citizen stops supporting the E168 the watch is finished, however good the titanium still looks. It scores 6.8, and the crystal is most of the gap.
Citizen's Super Titanium is surface-hardened, which is the point — plain titanium marks more easily than steel, and this does not. It is the closest thing on this list to a watch you can stop thinking about.

Citizen's five-year limited warranty excludes the power cell, case, bracelet and strap.
It scores highest of the three here at 7.7, and the two lines that get it there are the two you cannot upgrade later: a sapphire crystal, which is effectively unscratchable in daily wear, and a mechanical movement that a watchmaker can strip, clean and return to spec for as long as parts exist. Our formula gives both full marks, and it is right to.
The 8210 hacks, so you can stop the seconds and set it to the second, and 40mm with an integrated bracelet reads dressier than anything in the Promaster line. Citizen's five-year warranty is the longest term of any brand on this site.
Then the thing that cannot be undone. Citizen lists the lug width as 9.1mm. That is not a strap size — the bracelet is structurally part of the watch, so when it stretches or the clasp wears, no strap shop can help and your only recourse is Citizen. On a site that scores strap standardization because a strap is the part that fails most often, that single line costs it 0.8 of a point.
50m is the other limit: splashes and handwashing, not swimming. And Citizen publishes no lug-to-lug and no thickness for this reference, so you cannot check the footprint before ordering.
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.

Citizen's five-year limited warranty excludes the power cell, case, bracelet and strap.
This is the closest thing to an escape from the choice this page is about, and it is why it belongs here. The Garrison is the one Citizen that gets sapphire AND Super Titanium AND Eco-Drive in the same watch: nothing to wind, nothing to service, a crystal that will not mark, and a case that is both lighter than steel and hardened against scratches.
At 42mm it also sits between the other two in size, on a plain field dial running Citizen's three-hand E101 — no dual time, no calendar window, nothing competing for the space — with the same five-year warranty.
The price it pays is information. Citizen publishes no thickness, no lug-to-lug and no band width for this reference — so you cannot check the footprint, and you cannot buy a strap for it in advance without measuring the fitting yourself. That missing lug width costs it 0.7 of a point on its own and drops it to 7.2.
It is also 100m rather than 200m. Fine for swimming, short of the Promaster's diving rating, and the reason it is not simply the answer to the whole page.
Sapphire is the upgrade the 37mm Chandler never got, on a Super Titanium case with Citizen's five years of cover. Citizen publishes neither the thickness, the lug-to-lug nor the band width for this reference, so try it on before you commit to 42mm.

On a page about choosing between Citizens, this is the one to name as a mistake, because it is where the search for a cheaper Citizen usually lands: a light-powered dress watch, the same five-year warranty, the lowest price of any Citizen we cover.
Citizen publishes no meter rating for it. The field on its own product page reads Splash Resistant, which means handwashing is the limit. Every other watch on this page is rated 50m, 100m or 200m, and this one has no number at all — for a watch intended to be worn daily for years, that is a hard stop rather than a footnote.
With a mineral crystal and an odd 21mm lug width as well, it scores 4.9, the lowest figure of any Citizen in our registry. If the budget is the constraint, the Garrison above is the better answer and still a Citizen.

Tsuyosa +2.6, Promaster +1.7 — the 0.9 between 7.7 and 6.8.
Read the table rather than the total. The Tsuyosa's lead is built from what the watch is made of and whether it can be rebuilt; the Promaster's from what you can actually do with it. Neither of those is more important in the abstract — they are different questions, and only you know which one you are asking.
The integrated bracelet, which is the real decision
If one line on this page changes somebody's mind, it should be this one. A 9.1mm fitting is not a narrow strap, it is a bracelet engineered into the case, and the consequences run for the life of the watch. A bracelet is a wear part: links stretch, clasps loosen, and the end links that mate with the case are specific to that case. When a standard 22mm watch's strap goes, you replace it for the price of lunch, forever. When an integrated bracelet goes, you depend on Citizen still stocking that exact part.
That is a twenty-year question rather than a two-year one, which is why it barely registers in reviews and why this site weights it. The lug width guide explains how to measure a fitting and what the odd sizes cost, and the same objection applies to the Tissot PRX — PRX against the Tsuyosa sets the two integrated-bracelet watches against each other directly.
Mineral on a diver, sapphire on a desk watch
There is something backwards about how Citizen has allocated its crystals here, and it is worth saying plainly. The watch built to be knocked about — 200m, titanium, a diver's case — has the crystal that scratches permanently. The watch most likely to spend its life between a cuff and a keyboard has the crystal that does not.
Sapphire against mineral crystal sets out what each material actually is: sapphire is effectively unscratchable in daily wear, mineral collects marks you cannot remove, and the difference is worth 1.5 of our 2.5 crystal points. On the Promaster it is the single biggest thing holding the score down, and it is the reason the Garrison — same brand, same Eco-Drive, same titanium, but with sapphire — is on this page at all.
What five years of Citizen warranty actually covers
Both watches carry it, and it is the longest term of any brand on this site — but it is also the one with the widest exclusions. Citizen's limited warranty excludes the power cell, the case, the bracelet and the strap. On the Tsuyosa, whose bracelet is structurally part of the case, that exclusion is worth reading twice. Citizen's Eco-Drive warranty sets out what is left once the exclusions are applied.
Citizen also publishes no service prices at all, quoting every repair after inspection. That is why both watches score 0.4 of 1.0 on cost transparency where Seiko takes the full point for publishing $176 to overhaul a 4R and $296 for a 6R. What a watch costs to keep does the arithmetic against the brands that publish.
How to choose
Buy the Promaster BN0200 if you will swim in it, if you want titanium, or if being able to re-strap the watch forever matters to you.
Buy the Tsuyosa if you want sapphire and a mechanical movement in a dressier case, and the bracelet fits you when you try it on.
Buy the Garrison if you want sapphire, titanium and Eco-Drive together and can accept 100m and a maker that publishes none of the dimensions.
Do not buy the Corso as the cheap route into the brand. It is the only Citizen here with no meter rating at all.
The Promaster if the watch will be used: 200m, Super Titanium, a standard 22mm strap fitting and nothing to wind or service. The Tsuyosa if you want sapphire and a mechanical movement in a 40mm dress-adjacent case, and the integrated bracelet fits — because it can never be replaced.
Why does the Tsuyosa score higher if the Promaster is more capable?+
Because our formula scores what a watch costs to keep. The Tsuyosa wins crystal (sapphire against mineral, 1.5 points) and serviceability (a rebuildable mechanical movement against a replaceable module, 1.1), while the Promaster wins water resistance (0.9) and strap standardization (0.8). Net 0.9 to the Tsuyosa, at 7.7 against 6.8.
Can you replace the Citizen Tsuyosa bracelet?+
Not with a standard strap. Citizen lists a 9.1mm lug width, which is an integrated fitting rather than a strap size, so the bracelet is effectively part of the case. The Promaster takes any 22mm strap.
Does the Citizen Promaster BN0200 have sapphire?+
No — Citizen fits a mineral crystal, which collects scratches that cannot be polished out. If you want Citizen's titanium and Eco-Drive with sapphire in front of it, the Garrison BM8560 is the one that has all three, at 100m rather than 200m.
Which one can you swim in?+
The Promaster, rated 200m with a screw-down case. The Tsuyosa is rated 50m, which covers splashes and handwashing rather than swimming.
Is Super Titanium better than ordinary titanium?+
For scratching, yes. Plain titanium is lighter than steel but softer, and marks more easily; Citizen's Super Titanium is surface-hardened to resist that, and the hardness is in the metal rather than in a coating that can wear through.
What does a Citizen service cost?+
Citizen publishes no service prices and quotes every repair after inspection, which is why both watches lose 0.6 of a point on cost transparency. For comparison, Seiko publishes $176 for a 4R overhaul and Tissot $210 for a complete mechanical service.
