Hamilton Khaki Field Titanium vs Timex Expedition Titanium
Both titanium, both sapphire, both 20mm lugs, and one costs roughly three times the other. The gap is a named movement and two years of cover — against 100m of depth and a coating that wears out.
Buy the Timex Expedition Field Post Titanium for most wrists: 200m against the Hamilton's 100m, a published 50mm lug-to-lug where Hamilton publishes none, and bare titanium with no coating to wear through. Buy the Hamilton if you want a named 80-hour caliber you can price and service, and two years of cover rather than one.

41mm, 50mm lug-to-lug, 13.5mm, bare titanium, sapphire, 200m, 20mm lugs.
Sapphire, 200m and titanium at this money is a specification sheet Timex has no business hitting, and the 200m is the line that matters most here: it is double the Hamilton's rating, on the cheaper watch. If the watch is going to get wet, this is the one.
The verdict first: for most buyers, the Timex Expedition Field Post Titanium. It is rated 200m where the Hamilton is rated 100m, it publishes a 50mm lug-to-lug where Hamilton publishes no footprint at all, its titanium is bare rather than coated, and it costs roughly a third as much. On raw specification this is not close.
Buy the Hamilton Khaki Field Titanium if what you are paying for is the movement and the paperwork. It runs a named H-10 automatic with 80 hours of reserve and a Nivachron balance spring, Hamilton covers it for two years rather than one, and Hamilton publishes a service price list — European only, but a list, which is more than Timex offers. That is why it scores 8.6 against the Timex's 8.0 on this site's scale, even though the Timex has the better spec sheet.

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.
01Case metal and finish
Bare titanium against titanium under a black PVD coating. This is the line that decides the twenty-year question.
02Water resistance
200m against 100m, read from each maker's own document. The cheaper watch wins this outright.
03Published footprint
Timex publishes a 50mm lug-to-lug. Hamilton publishes none for this reference, so a 42mm case cannot be checked before ordering.
04Caliber disclosure
A named H-10 with 80 hours and a Nivachron balance spring, against an automatic Timex will not name and a reserve it does not publish.
05Warranty and service
Two years against one that excludes the crystal, strap, case and battery. Hamilton publishes a European service list; Timex publishes nothing.

01
Timex Expedition Field Post Titanium Automatic 41mm TW2Y90900
Best for: The one to buy, unless the movement is the point
Sapphire, 200m and titanium at this money is a specification sheet Timex has no business hitting, and the 200m is the line that matters most here: it is double the Hamilton's rating, on the cheaper watch. If the watch is going to get wet, this is the one.
It is also the only one of the two you can check before ordering. Timex publishes a 50mm lug-to-lug — the longest field figure on this site — and 13.5mm of thickness. Hamilton publishes neither for its titanium reference, so a 42mm case is a number on a box rather than a footprint on your wrist.
The titanium is bare, which sounds like a downgrade and is not. Nothing on this case can wear through; marks go into the metal itself and stay shallow. The 20mm lug width is standard, so straps are permanent and cheap.
The costs are real and they are all paperwork. Timex does not name the caliber and does not publish a power reserve, so you cannot look up what servicing it costs or who can do it. The warranty is one year and explicitly excludes the crystal, the strap, the case and the battery — close to everything that fails. That is the entire reason it scores 8.0 rather than higher; not one point of the gap is specification.
65 grams, sapphire and 200m is a spec sheet Timex has no business hitting. The one-year warranty is the reason to think about it: everything else here is covered for two to five.

This is the highest-scoring titanium watch on the site at 8.6, and the reasons are ownership reasons rather than specification ones. The H-10 is a named caliber with 80 hours of reserve and a Nivachron balance spring — Hamilton's antimagnetic alloy — so it holds rate around the laptops and phone cases that actually magnetize watches, and a watchmaker knows exactly what is inside before opening it.
Two years of warranty against the Timex's one, and Hamilton publishes a service price list. It is the European list with no US equivalent, which is a real gap, but it is a published number against Timex's nothing. Those two lines are most of the 0.6 between these watches.
At 11.45mm it is also the thinner watch by two millimeters, on a 42mm case that wears lighter than steel at the same size.
Now the thing to think hardest about, and it is the reason this is not the default pick: the titanium is under a black PVD coating, and a coating is a consumable. Titanium underneath is light and hypoallergenic, but once PVD wears through at the lug edges — which is where it always goes first — the fix is a refinish, not a polish. On a watch bought to keep for decades that is a cost the spec sheet does not show. The Timex has no coating to lose.
It is also rated 100m against the Timex's 200m, and Hamilton publishes no lug-to-lug for it.
Titanium plus PVD is the combination to think hardest about: the metal underneath is light and hypoallergenic, but a coating is a consumable — once it wears through at the lug edges, it is a refinish, not a polish.

The third way, and on the scratch question the best answer of the three. Citizen's Super Titanium is surface-hardened, so it resists the marking that plain titanium picks up — which is the one genuine weakness of the metal — and it needs no coating to get there.
It runs on light, so there is no winding, no battery change and no service interval to price, and Citizen covers it for five years, the longest term of any brand here. Sapphire and 100m on a 42mm case at the lowest price of the three.
Two real costs. Citizen publishes no thickness, no lug-to-lug and no band width for this reference, so you can check less about it than either watch above, and it publishes no service prices at all. And an Eco-Drive module is replaced rather than rebuilt, where both watches above are mechanical and can be returned to spec indefinitely. It scores 7.2. The Garrison against the Timex Titanium is compared in full on its own 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.

This is on the page as a warning against buying titanium for the wrong reason. If what you want from the Hamilton is the named caliber, the Nivachron hairspring and the two-year warranty, the steel Khaki Field Auto 38 gives you all three — the same H-10, the same 80 hours, the same sapphire, the same 100m — for less money than the titanium version.
It also publishes the number the titanium model does not: a 47mm lug-to-lug on a 38mm case, so you can check the fit before you order. And the case is bare steel, so there is no PVD to wear through at the lugs. It scores 8.6 — exactly level with the titanium Hamilton.
What you give up is the metal itself: steel is heavier than titanium at the same size, and on a 42mm case that difference is the reason people buy titanium in the first place. If weight is genuinely the problem you are solving, ignore this entry and buy one of the three above. If it is not, this is the cheaper way to the same movement.
Mechanically identical to the Murph and usually cheaper, because it does not carry a film's name. 47mm lug-to-lug on a 38mm case is a genuinely versatile footprint.

Our Keep Score reads six published specifications. On three of them these two watches tie: sapphire takes the full 2.5 on both, a rebuildable mechanical movement takes the full 2.5 on both, and a standard, even 20mm lug width takes the full 1.0 on both. The gap is made entirely of the other three.
Which nets out to the 0.6 between 8.6 and 8.0 — and note that none of it is the case metal.

Which nets out to the 0.6 between 8.6 and 8.0 — and note that none of it is the case metal.
That is worth saying plainly: the formula does not reward either watch for being titanium, because titanium is not one of the six things that decide whether a watch survives. It rewards Hamilton for telling you more and covering you longer, and it rewards Timex for the depth rating. What a watch costs to keep does the same arithmetic across the whole site.
Coated titanium against bare titanium
This is the argument neither of our other titanium comparisons makes, and on a buy-it-for-life site it is the most important one on the page. Hamilton finishes this reference in black PVD. The coating looks excellent and it does genuinely harden the surface while it lasts — plain titanium is softer than steel and picks up marks, which our titanium against stainless steel guide covers in full.
But a coating is a consumable. It wears at the high points first — the lug edges, the crown, the bracelet end links if there is one — and when it goes the repair is a refinish rather than a polish. Bare titanium behaves the opposite way: it marks more readily and the marks stay shallow, in the metal itself, where a light brush or simply time makes them part of the watch rather than damage to it.
Which you prefer is genuinely a matter of taste over a twenty-year horizon. What it is not is a free upgrade, and the more expensive watch here is the one carrying the wear part. The Citizen Garrison takes a third route — Super Titanium, which is surface-hardened rather than coated, so the hardness is in the metal and cannot wear off.
The footprint only one of them publishes
Hamilton publishes a lug-to-lug for the 38mm steel Khaki Field Auto — 47mm — and publishes none for either of its 42mm references, including this one. Timex publishes 50mm for the Expedition Field Post Titanium, which is the longest field figure on this site and the reason it appears on our field watches for large wrists page as the top pick.
So the fit advice splits cleanly. If your wrist is over about 185mm around, the Timex is the known quantity and the one that will not read small. If your wrist is under about 165mm, 50mm of lug-to-lug is a lot of watch and the Hamilton may well suit you better — but you will be finding that out after it arrives, because Hamilton will not tell you the number. Try it on if you can, or read watches for small wrists, which ranks the whole site on published footprint rather than diameter.
A named caliber against no caliber at all
Timex does not publish what is inside this watch and does not publish a power reserve for it. That is not a small omission on a mechanical watch you intend to keep: it means you cannot look up a service price before buying, cannot check parts availability, and cannot tell a watchmaker what to expect. Our most durable watches and watches that last a lifetime pages both weight that heavily, and it is why a watch with sapphire, titanium and 200m still lands at 8.0.
Hamilton's H-10 is the opposite case: a named caliber shared across the Khaki Field line, with 80 hours of reserve and a published antimagnetic hairspring. Hamilton still publishes no US service prices — the list is European — so you are better informed rather than fully informed.
How to choose
Buy the Timex if the watch will get wet, if your wrist is large, or if you want titanium and sapphire without paying Swiss money for them.
Buy the Hamilton if a named, serviceable 80-hour movement and two years of cover matter more than depth rating, and you accept that the PVD is a wear part.
Buy the Citizen Garrison if the scratch question is what worries you — Super Titanium is hardened rather than coated — and you would rather not service anything at all.
Buy the steel Khaki Field Auto 38 if the movement rather than the metal is what you are after. Same caliber, published footprint, no coating, less money.
Hamilton Khaki Field Titanium or Timex Expedition Titanium?+
The Timex for most buyers: 200m against 100m, a published 50mm lug-to-lug where Hamilton publishes none, bare titanium with no coating to wear through, and roughly a third of the price. The Hamilton if you want a named 80-hour H-10 caliber, two years of warranty and a published service list.
Why does the Hamilton score higher if the Timex has better specs?+
Because our formula scores what a watch costs to keep, not what it is made of. Hamilton wins warranty (2 years against 1) and service transparency (a published European price list against nothing), which is worth 0.95 between them; Timex wins water resistance, worth 0.4. The case metal is not scored at all.
Is the black PVD coating on the Hamilton a problem?+
It is a wear part. PVD hardens the surface while it lasts, but it goes at the lug edges first and the fix is a refinish rather than a polish. Bare titanium like the Timex's marks more easily but the marks stay in the metal. Citizen's Super Titanium is a third option: hardened rather than coated, so the hardness cannot wear off.
Which is better for a large wrist?+
The Timex, and it is the only one you can check. Its published 50mm lug-to-lug is the longest field figure on this site. Hamilton publishes no lug-to-lug for its 42mm titanium reference, so the fit is unknown until it arrives.
What movement is in the Timex Expedition Field Post Titanium?+
Timex does not say, and does not publish a power reserve for it either. That is the main reason it scores 8.0 despite having sapphire, titanium and 200m — you cannot price a service or check parts availability for a caliber nobody will name.
Is titanium worth paying extra for?+
For weight, yes — it is around 40% lighter than steel for the same case, and weight is the usual reason a larger watch stops being worn. For durability, no: titanium is softer than steel and marks more easily. Our titanium against stainless steel guide sets out both sides.
Is there a cheaper way to get the Hamilton movement?+
Yes — the steel Khaki Field Auto 38 runs the same 80-hour H-10 with the same Nivachron hairspring, sapphire and 100m, publishes a 47mm lug-to-lug, has no coating to wear through, and costs less than the titanium version. You give up the weight saving, which is the whole point of titanium.
