Buy quartz if you want accuracy and no maintenance. Buy automatic if you want a mechanical object that never needs charging. A quartz watch keeps time to roughly 15 seconds a month and needs a new battery every two to five years. A mechanical automatic typically runs somewhere between 10 seconds slow and 30 seconds fast per day, winds itself from the motion of your wrist, and wants a service every five to ten years. Quartz is the more accurate instrument by a wide margin. Automatic is the more interesting object. That is the entire decision.
One warning before anything else, because it is the mistake that ruins watches: a water resistance rating is not a swimming depth. Most dress watches, including five of the seven below, are rated 3 or 5 ATM, which means splashes and rain - not showers, not pools. The table further down says what each rating really covers.
Quartz vs automatic: the real differences
| Quartz | Automatic (mechanical) | |
|---|---|---|
| Power | A battery vibrates a quartz crystal 32,768 times a second | A weighted rotor winds a spring as your wrist moves |
| Typical accuracy | ±15 seconds per month | -10 to +30 seconds per day |
| Upkeep | A battery every 2-5 years, roughly $15-40 fitted | A full service every 5-10 years, commonly $200-600 |
| If you stop wearing it | Keeps running until the battery dies | Stops in about 36-48 hours; reset the time and date |
| Second hand | Ticks once a second | Sweeps in small steps, 6-10 per second |
| Feel | Thinner and lighter for the same case size | Thicker and heavier - you notice the rotor shift when you move |
| Same budget buys | Better case, crystal and finishing | A more complex movement, simpler finishing |
The practical read: if being correct matters - catching flights, timing meetings - quartz wins and it is not close. If you like that a spring and a few dozen jewelled bearings are keeping time on your wrist with no electronics involved, that feeling is what you are buying with an automatic, and you pay for it in accuracy and servicing.
What ATM water resistance actually allows
Ratings are measured as static pressure in a lab, not as someone swimming. Movement, water jets and temperature changes all push harder than the number suggests, so the honest guidance is stricter than the marketing.
| Rating | Equivalent | What it genuinely covers |
|---|---|---|
| 3 ATM | 30 m / 100 ft | Rain and handwashing splashes. Not showering, not swimming. |
| 5 ATM | 50 m / 165 ft | Splashes and brief accidental immersion. Light swimming at your own risk; no diving. |
| 10 ATM | 100 m / 330 ft | Swimming and snorkelling. |
| 20 ATM+ | 200 m / 660 ft and above | Scuba diving and water sports. |
Two more things that are true of every watch here: a push/pull crown must be pushed fully home or the rating means nothing, and the gaskets that make a watch water resistant harden with age, so a ten-year-old 5 ATM watch is not a 5 ATM watch any more.
Mineral or sapphire crystal?
This is the spec most people skip and then regret. Mineral glass sits around 5 on the Mohs hardness scale; sapphire is 9. Sand, keys, concrete and steel door frames all sit between the two, which is why a mineral crystal collects hairline scratches over a year of daily wear and a sapphire one usually does not. Sapphire is also harder to polish out, so when it does mark, it needs replacing rather than buffing. Of the watches below, only the Mathey Tissot has sapphire.
How to choose, in four questions
- Will you wear it most days? An automatic worn daily keeps itself wound and is a pleasure. An automatic worn occasionally is a small chore every time - you reset it before you leave.
- Does it need to be right? If you would be annoyed by a watch drifting a minute a fortnight, buy quartz.
- How big is your wrist? Case diameter matters more than any other number. Roughly: 27-34mm reads small and jewellery-like, 36-40mm suits most wrists of any gender, 42mm+ is deliberately large. Measure your wrist before falling for a 46mm case.
- Where will it get wet? If the answer is anything beyond rain, you need 10 ATM, and that means looking outside this list.
Seven watches in stock, and who each one is for
All seven are in stock as this is written. Three are automatics and four are quartz, and the prices run from about $108 to $718, so the comparison below is a real one rather than a single-brand showcase.
Best quartz overall
Mathey Tissot Men's Edmond H1886QABU
$360 · Bids.com
The only watch here with a sapphire crystal, which is the upgrade that actually shows after a year of wear - mineral glass picks up fine scratches, sapphire does not. Swiss-made quartz, 42mm steel case, date window, 5 ATM. If you want one watch you can stop thinking about, this is it.

Entry automatic
Christian Van Sant Men's Cyclone Automatic CV0141
$518 · Bids.com
The cheapest way into a real mechanical movement here. 46mm steel case on a brown leather strap, 5 ATM. Wear it daily and it winds itself; leave it in a drawer for two days and you will reset it. That trade is the whole point of an automatic.

Most watch for the money
Christian Van Sant Men's Grandeur CV2135
$718 · Bids.com
An automatic with a multi-function moon phase in a 45mm rectangular case - an unusual shape at this price, and the complication is the kind of detail normally found much higher up. Blue dial, blue leather, 5 ATM.

If you want to see the movement
Christian Van Sant Men's Dome CV0748
$638 · Bids.com
A skeleton dial over a 22-jewel automatic under domed "bubble" glass, so the mechanism is the design. Note the 3 ATM rating: this is a dry-wrist dress watch, not something to wear swimming.

Dress and occasion
Locman Women's Diamond Nuovo 028MOPKD/PK
$410 · Bids.com
Italian-made, 40mm oval case, mother-of-pearl dial on a pink leather strap. Mother-of-pearl shifts colour as the light moves, which is why it photographs so well and why no two dials are identical.

Minimalist daily wear
Skagen Women's Signatur SKW2794
$158 · Bids.com
A 38mm case and a clean grey dial on grey leather - Danish design doing the thing it is known for. 38mm reads as a modern, slightly oversized womens size rather than a dainty one.

Smallest and best value
Obaku Women's Classic V146LXVNMN
$108 · Bids.com
A 27mm case on a steel bracelet for the least money here. If you want a watch that works as jewellery and disappears under a cuff, small cases like this are the ones to look at.

Match the movement to how you live, then check the crystal, then check the water rating. A sapphire quartz watch at $360 will look better in three years than a mineral-glass automatic at $700 that has been scratched and left unworn. Browse what is actually in stock in quartz and automatic watches.
Frequently asked questions
Is a quartz or automatic watch better?
Neither is better outright - they fail differently. Quartz is far more accurate (about 15 seconds a month against 10-30 seconds a day), costs less for the same quality of case and finishing, and needs only a battery every few years. Automatic needs no battery, winds itself from your wrist and appeals to people who want a purely mechanical object, but it drifts more, weighs more and needs a service every five to ten years. Choose quartz for accuracy and convenience, automatic for the object itself.
How long does an automatic watch run when you take it off?
Most automatics hold a power reserve of about 36 to 48 hours, so one left off overnight is still running in the morning but one left off over a weekend has stopped. You restart it by winding the crown or simply wearing it again, then resetting the time and date. Watches worn only occasionally are the reason watch winders exist.
Can I shower or swim with a 3 ATM or 5 ATM watch?
No to showering in either case, and no to swimming in a 3 ATM watch. A 3 ATM / 30 m rating covers rain and handwashing splashes only. 5 ATM / 50 m covers splashes and brief accidental immersion, and light swimming is at your own risk. Hot showers are worse than cold water because heat expands the metal and softens the gaskets, and soap degrades them. You want 10 ATM for real swimming.
Does a watch need servicing if I never wear it?
Yes, if it is mechanical. The lubricants inside an automatic thicken and migrate whether or not it is running, so a watch sitting in a drawer for a decade can need a service before it runs properly again. A quartz watch left unworn has a different problem: a dead battery can leak and corrode the movement, so remove the battery if you are storing one long-term.
What size watch case should I buy?
Measure your wrist circumference first. As a rough guide, 27-34mm reads small and jewellery-like, 36-40mm suits the majority of wrists regardless of gender, and 42mm and above is a deliberately large look. Just as important is lug-to-lug length - the distance across the case from one strap horn to the other - because a case that overhangs the flat part of your wrist will never sit comfortably no matter what the diameter says.
Is sapphire crystal worth paying more for?
For a watch you wear most days, yes. Sapphire is 9 on the Mohs hardness scale against roughly 5 for mineral glass, and most of what scratches a watch in daily life - sand, grit, keys, stone and steel - falls between those two numbers. That is the difference between a dial you still look through clearly in three years and one hazed with fine scratches. The trade-off is that sapphire chips rather than scratches when struck hard, and cannot be polished out.
