Field Watches for Hiking and Camp: Solar, Lume and Water Ratings Compared

A field watch for hiking needs four things: a dial you can read at a glance, a light or lume for the tent, a water rating that covers rain and the odd river crossing, and a strap that dries. Everything below is analog, two to three hands and a date, and runs for months or years without a charger.

How we chose: we picked from makers' spec sheets and listings sold by Amazon.com, checked on October 1, 2026, and have not tested these watches. Many watch listings on Amazon come from third-party sellers who may be grey-market, without the maker's US warranty; we left those out.

What the water rating on a watch means

Watch water ratings are a pressure test, not a promise for any depth. Garmin's water rating definitions put 5 ATM at the pressure of 50 m of water and 10 ATM at 100 m. Garmin also warns that a watch may let water in if an activity creates more pressure than its rating.

Casio's watch care table turns that into uses. A watch marked only "water resist" handles hand washing and rain. Five bar adds swimming and water work. Ten bar and up adds windsurfing and skin diving. None of them is for scuba.

None of these listings names the test standard behind its figure; ISO 22810 is the international one for water-resistant watches. Read the number by the maker's own table.

Prices are Amazon's, as of the time shown, and subject to change. Details

The Casio figures come from Casio's spec sheets; the Timex and Citizen figures from their Amazon listings.

Lume, backlight or both

A backlight shows the dial on demand; lume glows on its own after the hands have soaked up light. In a tent at 3 a.m. you want one or the other.

The Timex has both: the INDIGLO button lights the whole dial, and the hands are luminous, per the listing. The Citizen Garrison and Weekender have luminous hands and markers. The Casio Forester has an amber LED with afterglow, per Casio's Forester spec sheet.

The Casio MTP-S120L is the gap. Casio's MTP-S120L spec sheet lists no luminous hands or light. Skip it if you check the time in the dark.

Solar, Eco-Drive or a battery

Solar watches still have a cell inside; light keeps it topped up. Casio says the MTP-S120L runs about 8 months from a full charge until the hands stop, so a week in a dark pack is no issue. Citizen says Eco-Drive is "powered by light, any light" and never needs a battery change, per the Garrison listing.

The Timex and the Casio Forester run on ordinary batteries. Casio quotes about 3 years for each of the Forester's two cells, one for the watch and one for the light.

Which to buy comes down to whether you mind a battery change every few years. A solar watch removes that chore; a battery watch is lighter and simpler.

Straps for wet days

The strap matters more than the case on a wet trip. A nylon strap like the Timex's or the Forester's hook-and-loop band gets wet and dries again. The Weekender's rubber strap does not soak up water at all.

Leather-strap versions of the Timex Expedition and Citizen Eco-Drive watches sell next to these. We would keep those for dry days. The Garrison's steel bracelet copes with water, but it is cold against the skin on a winter morning.

If you plan to swap straps, check the lug width first. Casio's Amazon listing for the MTP-S120L series gives 22 mm.

The Seiko 5 Sports Field, and why it has no card

The Seiko 5 Sports Field series is a popular automatic field watch, but every listing we found on October 1, 2026 came from a third-party seller, not Amazon.com or Seiko. Buy it from Seiko or a dealer Seiko lists, so the warranty is not in question.

Frequently Asked Questions

Can I swim with a 50 m field watch?

Briefly. Timex's listing for its Expedition Metal Field, with the same 50 m rating, says it suits short periods of recreational swimming but not diving or snorkeling. For regular swims or paddling, pick a 100 m watch.

Is a digital ABC watch better for hiking than an analog field watch?

It does more: altitude, a barometer and a compass. An analog field watch is lighter, simpler and usually cheaper, and it never needs a sensor calibrated. See our storm alarm watch guide for the ABC side.

Do I need to keep a solar watch in the sun?

No. Casio's Amazon listing for the MTP-S120L series says its solar cell charges from "even faint light from fluorescent lamps." Leave it face-up near a window between trips rather than in a drawer.
