Buying your first good watch: what to look for
A well-made watch can run for decades, but a spec sheet rarely tells you whether it will suit your wrist or your routine. These sections cover what to understand before you spend serious money, from what drives the hands to who stands behind the warranty.
Choose a movement: quartz, automatic or manual-wind
Most quartz watches keep time with a battery and a tiny quartz crystal that vibrates 32,768 times per second. Quartz is usually cheaper and far more accurate than a mechanical movement: a typical quartz watch drifts by seconds per month and needs only a new battery every few years.
Mechanical watches run on a coiled mainspring. An automatic winds itself through a weighted rotor that turns as your wrist moves, while a manual-wind watch needs winding by hand, usually once a day. Mechanical watches commonly gain or lose several seconds a day, sometimes more, and most stop within one to three days if you leave them off.
A COSC chronometer certificate means Switzerland’s official chronometer testing institute found the movement’s average daily rate to fall between 4 seconds slow and 6 seconds fast, the limit for all but the smallest mechanical movements. Some brands publish stricter in-house standards, and an uncertified watch can still run within those limits.
Pick complications you will actually use
A complication is any function beyond telling the time. Each one adds cost, thickness and parts that need servicing, so choose features that fit your ordinary week.
On many mechanical watches, using the quick-set date while the hands sit near midnight can damage the date mechanism. Move the hands to around 6 o’clock before you change the date.
- Date: the most practical extra for most people.
- Chronograph: a stopwatch started and stopped by pushers on the side of the case.
- GMT: an extra 24-hour hand that tracks a second time zone for travel or remote work.
- Moon phase and power reserve displays: charming, but mostly a matter of taste.
Size it to your wrist
Case diameter gets the attention, but lug-to-lug length, measured from the tip of the top lugs to the tip of the bottom ones, decides how a watch sits. If the lugs hang past the edges of your wrist, the watch is too big for you, whatever its diameter.
Thickness matters too, because a tall case catches on shirt cuffs and can feel top-heavy. Try watches on before you buy when you can, or cut a paper template to the listed dimensions and hold it against your wrist. Note the lug width, usually an even number of millimeters, so replacement straps fit.
Read water resistance ratings correctly
The depth printed on a dial is a laboratory pressure rating, not a promise that the watch survives that depth in real use. Movement through water, temperature swings and aging gaskets all eat into the margin, and a crown that screws down must be screwed in fully before the watch gets wet.
- 30 m (3 bar): splash resistance for rain and hand washing, not swimming.
- 50 m: brief, gentle swimming at most, depending on the maker.
- 100 m: generally suitable for swimming and snorkeling.
- ISO 6425 dive watches: rated to at least 100 m and tested for diving use.
Compare crystals and straps
Synthetic sapphire, rated 9 on the Mohs hardness scale, shrugs off nearly all everyday scratches but can chip or crack from a hard knock. Mineral glass costs less and scratches more easily. Acrylic scratches most easily of all but rarely shatters, and light scuffs polish out with a little plastic polish.
A steel bracelet suits most occasions; look for solid end links and a clasp with micro-adjustment for hot days, when wrists swell. Leather is comfortable but dislikes water and sweat, while rubber and fabric straps handle swimming and summer heat. Quick-release spring bars let you swap straps without tools.
Buy from a source that stands behind the watch
An authorized dealer sells new watches with the manufacturer’s full warranty, though popular models may come with a waiting list. Gray-market sellers offer genuine new watches outside the brand’s official network, often at a discount, but the warranty may come from the seller rather than the manufacturer.
Pre-owned watches can be excellent value if you verify what you are buying. Ask for clear photos of the case back, the serial and reference numbers and the movement, and buy where you get a return window and independent authentication.
- Box and papers: the warranty card or certificate should match the watch’s serial number.
- Service history: receipts showing when, where and by whom it was last serviced.
- Original parts: replacement dials, hands or bezels can cut value sharply.
- Case condition: heavy polishing rounds off sharp edges and lowers value to collectors.
Plan for servicing
A mechanical watch is a tiny machine whose oils thicken and wear with time. Follow the manufacturer’s recommended service interval, which is often several years. A full service usually includes disassembly, cleaning, fresh lubrication, regulation, new gaskets and a water-resistance test.
Don’t wait for the schedule if the watch suddenly runs far fast or slow, the power reserve shrinks or moisture appears under the crystal. Ask whether the brand’s service center or an independent watchmaker will do the work, and get the price and turnaround time in writing. Quartz watches need less attention, but replace a dead battery promptly, since an old one can leak.
