The Best Watches Under 100

What a sub-100 budget really buys

Spending under 100 dollars on a watch used to mean compromise. It no longer does. At this tier you can buy a genuinely good watch rather than a disposable one, provided you set your expectations correctly. What the budget buys you is honest engineering: reliable quartz movements that keep time to within a few seconds a month, cases that survive years of daily wear, and a handful of models that have been in production so long the factory has perfected them. What it does not buy you is a sapphire crystal, a precious-metal case, or a true desk diver. Keep those two lists straight and you will be very happy here.

This is also the tier Casio owns. No other brand offers as many genuinely good watches under 100 dollars, which is why most of the picks below wear the Casio name. The one exception is the step up at the end, where a single mechanical Seiko changes the conversation.

The digital classics

If you want one watch that defines the budget tier, it is the Casio F-91W, Black Dial. It has been made for decades, weighs almost nothing on a compact resin case, about 35 mm wide and 38 mm lug-to-lug, runs for years on a single battery, and does everything a digital watch should: alarm, stopwatch, light, and daily accuracy you will not need to correct. It is the default recommendation for good reason.

For a slimmer wrist or a more retro look, the Casio LA-670WA, Black Dial shrinks the same digital reliability into a roughly 30 mm steel-bracelet case. From a distance it reads as jewellery, up close as a tool, which is a rare combination at any price.

When you want more screen and more function, the Casio AE-1600H, Clear Dial goes large at 49.7 mm with dual time, in an opaque black resin case. It is the digital that most resembles a tool, and the toughest of the digital trio.

The affordable analogue options

Not everyone wants a digital display. For an analogue dress watch, the Casio LTP-V007G, Gold Dial is a small, gold-toned, three-hand piece that looks far dearer than it is. It is the one to wear with a shirt when a digital would look out of place.

For something rugged with hands, the Casio MRW-200H, Black Dial is a 44.6 mm analogue with a rotating bezel and 100 metres of water resistance. It is the closest thing to a field watch you will find at this money: legible, light, and unbothered by rain, sweat, or a knock against a doorframe.

The toughest pick

If durability is the one thing you care about, the MRW-200H and the AE-1600H are the two to weigh. The MRW-200H gives you real water resistance and a proper bezel in an analogue package; the AE-1600H gives you a sealed digital that takes abuse and never asks for attention. For anyone who works with their hands, the MRW-200H is the one I would reach for.

Who each one suits

• Want the one definitive budget watch: the F-91W
• Want a compact or retro digital: the LA-670WA
• Want maximum function and toughness in digital: the AE-1600H
• Want an affordable analogue for a shirt: the LTP-V007G
• Want a rugged analogue with a bezel: the MRW-200H

Stepping up

The moment you want a mechanical movement, you have left this tier. The natural next step is a Seiko 5, Silver Dial, a 37 mm automatic that runs without a battery and has been a first mechanical watch for generations. It sits just above 100 dollars rather than below it, which is exactly why it belongs in the next guide.
