Best Automatic Watches Under $100

Why the list is this short

A self-winding mechanical movement has somewhere between 21 and 24 jewels, a wound mainspring, a rotor on a pivot and an escapement beating six or eight times a second. Building one to a standard where it will still run in ten years costs money, and that cost does not compress indefinitely.

Below roughly $90 the only way to hit the price is to cut the things you cannot see: undocumented movements, unrated cases, mineral crystals seated in cases that are not sealed, and no parts supply. The watch will run for a while. It will not be serviceable, and nobody will tell you what is inside it. Our standard is in how we test, and it rules that entire tier out.

The one genuine automatic under $100

The Invicta Pro Diver 8926 is the answer, and it is a surprisingly good one: a Miyota 8215 - a movement that has been in production for decades, hand-winds, and can be serviced by anyone - in a 200m case with a screw-down crown and a unidirectional bezel.

The caveats are real. The 8215 historically does not hack, so you cannot set the seconds precisely; Miyota only began fitting a stop-seconds device to part of this family around 2018-19, and you cannot count on it. Invicta's quality control is variable, and the design is a close Submariner homage, which is its own conversation - we have that one here. But as engineering per dollar it is difficult to argue with, and Seiko vs Invicta puts it against the obvious alternative.

The quartz watch that beats it

We have to say this even though it undermines the premise of the page. The Casio Duro MDV106 is a 200m dive watch with a screw-down crown, a unidirectional bezel and a mineral crystal for under $70, and it keeps time to seconds per month rather than tens of seconds per day.

It is quartz, so it fails the only test that matters if you specifically want a mechanical watch. But if what you actually want is a tough, accurate, cheap watch, the Duro is the better purchase and nothing on this page beats it. Settle automatic vs quartz before you spend, and if you want the direct fight, Duro vs Mako is it.

The two worth waiting for

If you can stretch past the $100 line - and the difference is often two or three weeks of saving - the watch you get changes category.

• Around $140: the Fossil Townsman Automatic. A real open-heart mechanical with an exhibition caseback, so you can watch the balance work. Fossil does not publish the caliber, which is a genuine mark against it.
• Around $250 to $300: the Orient Ray II (or its twin the Mako II). An in-house F6922 published at -15 to +25 seconds a day, hacking and hand-winding, day-date, 200m and a screw-down crown. This is where the value curve in this market genuinely peaks.

The step from the Invicta to the Orient is the single biggest quality jump available in affordable watches, and it is why the under-$300 list is the one we point most people at.

What we will not put on this list

Unbranded and near-unbranded automatics sold with a stock photo, a "Japanese movement" claim and no caliber number. They are everywhere at $30 to $80, and the pattern is consistent: no published accuracy specification, no stated water-resistance figure in meters, no service parts, and a case that is water resistant until the first time it is not.

If you are shopping that tier anyway, buying watches on Amazon safely covers the checks that matter, and the movement comparison explains what a named caliber buys you.

The bottom line

Under $100, buy the Invicta if you want mechanical and the Casio if you want a good watch. If you can wait, wait - the under-$200 and under-$300 lists are where the arithmetic starts working in your favor, and the value list ranks the whole field by what you actually get per dollar.
