How to pick a watch under $50 that lasts

A $40 watch worn every day for two years costs about 5 cents a day. That is hard to beat.

Under $50 you will not get a luxury watch. You will get one that tells the time, survives a handwash and does not make you think about it.

What to look for

Quartz movement. It runs on a battery, is accurate and needs no winding. Under $50, quartz is the right choice.

A simple face. Clear numbers or markers, with hands that contrast with the dial. You should be able to read it at a glance.

A decent strap. Silicone and nylon straps are cheap, comfortable and easy to replace. Leather at this price is often thin.

Mineral or hardened glass. Plain plastic scratches quickly. Check the listing.

A replaceable battery. Most are. A cell usually lasts one to three years.

Water resistance: what the numbers mean

The rating does not mean you can dive to that depth. It is a lab test under static pressure.

Hot showers and steam can damage seals even on rated watches. If you swim, aim for 50m or better and rinse it in fresh water.

At this price you get / do not get

You get: - Accurate timekeeping - A readable face - A decent daily-wear body

You do not get: - A long warranty - Sapphire glass - A movement made to be serviced

Walk away if

• The listing claims it measures blood pressure or blood sugar.
• There is no water-resistance rating at all and you need one.
• All the reviews are from the same two weeks.
• The strap is glued and cannot be swapped.

Smartwatches and fitness bands

Basic bands under $50 can count steps and show notifications. Battery life, screen quality and app support are the weak points. Accuracy of heart rate and sleep numbers is rough on cheap models. Treat them as guides, not medical tools.

Is it worth it?

Divide the price by days worn. A $45 watch worn for 730 days costs about 6 cents a day. For a broader look at the math, see cost per use.
