Hamilton Khaki Field Murph 38mm H70405130

Timex vs Hamilton

Timex vs Hamilton

Both trade on American military heritage and both sell field watches. One is made to a price; the other is a Swiss watch with an 80-hour movement.

By Sawyer V. · Published

The short answer

Buy Hamilton if you intend to keep the watch: 80-hour ETA-based movements with Nivachron balance springs, sapphire across the Khaki line, and published dimensions on several references. Buy Timex for the Expedition automatics, which give you sapphire and 200m for far less — accepting that Timex publishes no caliber and no service price.

Both brands lean on the same history — American watches issued to American soldiers — and both sell a field watch as their signature. That is where the similarity stops. Hamilton is a Swiss brand inside the Swatch Group; Timex is a mass-market American company building to a price.

The interesting part is that Timex's Expedition automatics are better specified than their price suggests, and in two places they beat the Hamiltons outright. Whether that is enough depends on how long you intend to own the watch.

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. 01Movement disclosure

    Hamilton names the H-10, H-40 and H-50. Timex does not publish the caliber in any of its automatics.

  2. 02Power reserve

    80 hours across the Hamiltons here. Timex publishes no reserve figure at all.

  3. 03Crystal

    Sapphire on every Hamilton here except the Pilot Pioneer. Timex is mixed — sapphire on Expedition, acrylic or mineral elsewhere.

  4. 04Warranty

    Two years from Hamilton. One from Timex, excluding the crystal, strap, case and battery.

  5. 05Where Timex wins

    Price, 200m on the Expedition line, and published lug-to-lug figures Hamilton does not always give.

An 80-hour automatic with a Nivachron antimagnetic balance spring, sapphire and 100m, in the 38mm case the field style was designed around. The dial is the reason most people buy it.

ETA-based, so any competent watchmaker can service it and parts are not a question.

Hamilton publishes no lug-to-lug for this reference, where it does for the Khaki Field Auto — and no US service price, only 230 euros for Europe.

Hamilton fits Nivachron across the Khaki Field line — an antimagnetic hairspring, addressing the failure mode that used to send affordable mechanicals to the bench. This is a watch designed around the twenty-year case.

Mechanically identical to the Murph — the same 80-hour H-10, sapphire, 100m and two-year warranty — with a published 47mm lug-to-lug so you can check it against your wrist.

38mm, 11mm thick, on a 20mm strap width that takes anything ever made.

The plainer dial of the two, which is either the appeal or the reason to buy the Murph instead.

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.

9.5mm because there is no rotor — the thinnest field watch on this site — with the same 80-hour reserve and sapphire.

Hand-winding is a daily habit rather than a chore for most people who choose it deliberately.

50m rather than 100m, so rain and hand-washing only.

No rotor means fewer parts and a thinner case, and the H-50 runs 80 hours on a wind. This is the simplest genuinely good mechanical watch on this site, and simple is what survives.

Sapphire and 200m on an automatic, at a price no Hamilton approaches. On those two specifications it beats every Hamilton here, which are 50m and 100m.

41mm with a published 48mm lug-to-lug — and Timex publishing that figure puts it ahead of the Murph, which does not.

Timex does not name the caliber, so nobody can price a rebuild, and the one-year warranty excludes the crystal, strap, case and battery.

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.

A titanium case with sapphire and 200m — around 40% lighter than steel, and a materials specification that costs far more elsewhere.

Timex publishes the 50mm lug-to-lug, so the fit is checkable before buying.

That 50mm is the longest published field-watch figure on this site, so it overhangs anything under about 17.5cm, and the caliber is again unnamed.

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.

A real automatic in a case drawn from Timex's own 1960s catalog, under a domed acrylic crystal that polishes out at home when it scratches.

20mm lugs and 50m, which covers rain and hand-washing.

No published caliber, no published reserve and no service price. A watch to enjoy rather than to keep.

Acrylic reads as a downgrade and mostly is not: it scratches easily and polishes out with a cloth and a tube of paste, which sapphire does not. On a watch you intend to keep for decades, that is a feature.

The Weekender is Timex's most famous watch and the clearest example of what this site scores badly.

A brass case rated 30m under a mineral crystal that cannot be polished back, on a CR2016 battery, with a warranty that excludes the crystal, strap, case and battery — nearly everything that fails.

The Expedition automatics above are the Timexes worth owning: sapphire, 200m and published dimensions, for not much more.

A brass case at 30m, with a warranty that excludes the crystal, the strap, the case and the battery — which is to say almost everything that fails. Buy it as a strap-swapping toy, not as a watch to keep.

The two places Timex genuinely wins

Water resistance and price. The Expedition automatics are rated 200m; the best Hamilton here is 100m and the hand-wound is 50m. For a watch that will swim, that is not a small thing, and it is worth saying plainly on a page where the Swiss brand otherwise dominates.

Timex also publishes lug-to-lug figures on several references where Hamilton does not — including for the Murph, one of its best-known watches. A maker who publishes the number that decides fit is doing something useful, whatever the price.

What the Swiss premium actually buys

An 80-hour reserve, a named ETA-based caliber any independent can service, a Nivachron balance spring that handles the magnets in laptops and phone cases, and sapphire as standard rather than as an upgrade tier.

The reserve is the most noticeable day to day: put a Hamilton down on Friday and it is running on Monday. The named caliber is the most valuable in the long run, because it turns an eventual service from a quote into a known cost.

Which to buy

If this is a watch to keep, buy the Hamilton Khaki Field Auto — 80 hours, sapphire, 100m and a published lug-to-lug. If it is a first mechanical watch, or one to knock about without worrying, the Timex Expedition Pioneer Automatic gives you sapphire and 200m for a fraction, and you accept an unknown service cost in exchange.

Our Timex versus Tissot comparison makes the same argument against the other Swiss brand this site covers, and reaches a similar conclusion for similar reasons.

Questions people actually ask

Is Hamilton better than Timex?

For keeping, yes: named 80-hour ETA-based movements, Nivachron balance springs, sapphire and a two-year warranty. Timex's Expedition automatics beat Hamilton on water resistance and price, at the cost of an unnamed caliber.

What movements does Hamilton use?

ETA-based calibers from within the Swatch Group — the H-10 and H-40 automatics and the hand-wound H-50, all with 80-hour reserves and Nivachron balance springs.

Are Timex automatics any good?

The Expedition line is genuinely well specified — sapphire and 200m at a low price. The catch is that Timex does not publish the caliber, so an eventual service cannot be priced in advance.

Which has the better warranty?

Hamilton, at two years. Timex offers one year and explicitly excludes the crystal, strap, case and battery.
