A field watch for less than lunch.
A 42mm steel-cased quartz with a cream dial, black numerals, luminous hands and a nylon strap. It exists to put a legible analogue watch on your wrist today. It is a placeholder, and it knows it.

What the money buys
A 42mm stainless steel case, a battery-powered Japanese quartz movement, a mineral crystal, luminous hands and markers, and a woven nylon strap. The dial is cream with black Arabic numerals and a smaller inner ring of 24-hour numerals, which is the classic field-watch layout.
That layout is the reason to buy it. It is legible at a glance, in the way military field watches were designed to be, and it costs less than most people spend on lunch.

The water-resistance muddle
The Amazon listing gives two different water-resistance figures: 30m in the specification table and 5 ATM in the title. Those are not the same thing. We treat it as the lower one, which means rain and handwashing, not swimming.
A listing that disagrees with itself is a fair warning about the rest of the specification too. Nothing on this page has been checked against a manufacturer, because there is no manufacturer page to check.

A placeholder, honestly
This is the watch you buy while you decide what you actually want, or the one you wear where a better watch would get wrecked. It will do the job of telling the time legibly, and the nylon strap can be swapped for almost anything.
If you find yourself liking the look, the Hamilton Khaki Field Mechanical on this site is the same dial idea done properly, with a hand-wound Swiss movement and a specification you can verify. This one is the sketch of that watch, not the watch.

FAQ
Battery-powered. The listing describes a Japanese quartz movement, not an automatic or hand-wound caliber.
