Frequently Asked Questions

No. An automatic watch is purely mechanical — it stores energy in a wound mainspring, not a battery. Wearing it winds it from the motion of your wrist, and most can also be wound by hand through the crown.

Usually not. Normal daily wear keeps an automatic wound through its rotor. If you leave it off past its power reserve — commonly around 40 hours — it stops, and you just wind it and reset the time.

The seconds hand sweeps rather than ticks once per second, because the balance wheel beats several times a second. A Seiko 4R36, for example, runs at 21,600 beats per hour — six per second — so up close you see a smooth sweep, not a quartz tick.

Affordable automatics are rated in tens of seconds per day — Seiko states its 4R36 at roughly +45 to -35 seconds a day, for instance. That's normal and fine for the price. A Swiss COSC-certified chronometer runs much tighter, to -4/+6 seconds a day.

No — a quartz watch is far more accurate day to day. Automatics are bought for the mechanical craft, the sweeping seconds hand and needing no battery, not for accuracy.

Yes. A mechanical movement is designed to be cleaned and re-oiled periodically, commonly every several years, like any precision machine. It's a real ongoing cost that quartz watches don't have.

Usually no. If you wear one regularly, your wrist keeps it wound. A winder mainly helps if you rotate several automatics, or own a watch with a calendar or moonphase you'd rather not reset. See our full guide on whether you need one.

No — a healthy movement is built for it. The winding mechanism slips once fully wound, so it won't overwind. The things that matter are a sensible turns-per-day setting and a quiet motor if it lives in a bedroom.

For most modern automatics, start around 650–800 turns per day, bidirectional, then increase if the watch loses time on the winder. Starting low and adjusting beats guessing a high number. Our TPD settings guide has a table by movement and brand.

Yes. A movement only winds when the rotor turns the correct way. Most modern movements wind in both directions, so a bidirectional setting is the safe default; a few (like the Miyota 8215) wind only one way and need more turns or the right direction.

For most people, a Seiko 5 Sports or an Orient — reliable in-house movements, well under $500, and long-lasting. For a diver, the Orient Kamasu; for a dress watch, the Orient Bambino. Our entry-level and under-$500 roundups lay out the options.

You can get a genuinely good automatic with an in-house movement for $100 to $300, so there's no need to overspend. The under-$500 band is the value sweet spot; under $1,000 buys nicer finishing and a sapphire crystal.

A watch marked 'Diver's [depth]m' meets ISO 6425, a standard that requires a minimum 100m rating, a unidirectional elapsed-time bezel, dark legibility, and testing of every piece. A plain '200m water resistant' watch meets the lighter ISO 22810 standard instead.

Sapphire is far more scratch-resistant than mineral (or acrylic) glass, though it can shatter on a hard knock. On budget watches a mineral crystal is common; paying up for sapphire — as on the Orient Kamasu over the Mako II — is one of the clearest upgrades your money buys.

No, and it's worth checking. 'Hacking' means the seconds hand stops when you pull the crown, so you can set the time precisely; hand-winding lets you wind via the crown. Most modern movements do both, but some older or budget calibers do neither — we note it on every watch.

A box stores and displays watches; a winder actively rotates an automatic to keep it wound while it's off your wrist. Most people need a box; a winder only earns its place if you rotate several automatics or hate resetting a calendar.

No, and we say so plainly. We don't own a test lab. Instead we compare each watch on its published movement and case specs, do the turns-per-day and power-reserve math, and check the live price. Our methodology page explains exactly how.
