Automatic or Quartz: What Each One Needs From You
One needs to be worn. The other needs a battery changed properly. The maintenance habits that actually differ between the two, without the snobbery.
The automatic-versus-quartz argument is usually about romance. This is not that article. Both are good machines; they simply ask different things of the person who owns them.
What an automatic asks for
Movement. A rotor inside the case spins as your wrist moves and winds the mainspring. Worn daily, the watch never stops. Left in a drawer, a typical automatic runs for 38 to 72 hours and then halts.
Stopping is harmless. Restarting is a five-second job: a few turns of the crown, then set the time. What people get wrong is how they set it.
- Never set the date between roughly 9 pm and 3 am. The date mechanism is already engaged in its overnight change during that window and forcing it can break a tooth off the date wheel. This is the single most common self-inflicted repair on a mechanical watch. If you are unsure, move the hands to around 6 o'clock first, set the date, then set the time forward to the correct hour.
- Wind gently and stop when it resists. On a hand-wound movement you will feel the mainspring reach its end. On an automatic you generally cannot overwind it — there is a slipping clutch — but there is no reason to keep going past thirty turns.
- Screw the crown back down if it screws. An unscrewed crown is how a water-resistant watch stops being one.
Service. Every five to seven years, or when it starts losing more than about fifteen seconds a day. A service is not optional maintenance dressed up as an upsell — the oils genuinely degrade, and running a dry movement wears the pivots.
What a quartz watch asks for
Almost nothing, and then one thing that really matters.
Change the battery before it dies, not after. A dead cell left inside a watch can leak, and the residue corrodes the movement. Some quartz watches signal a dying battery by making the seconds hand jump in four-second steps instead of one — that is your warning, and you have a few weeks.
Have it changed by someone who will replace the gasket. Opening a caseback breaks the water seal. A two-euro battery change that skips the gasket is how a watch that survived ten years of rain suddenly fogs up in a shower.
Beyond that: a quartz watch does not care whether it is worn. It does not need a winder — there is nothing to wind. It keeps better time than almost any mechanical watch, typically within fifteen seconds a month.
What both of them need
- Distance from magnets. This affects automatics badly — a magnetised hairspring can make a watch gain minutes a day — and quartz barely at all. Phone cases, laptop lids, speaker grilles, magnetic clasps. Demagnetising is cheap and quick, so if an automatic suddenly runs wildly fast, suspect magnetism before you suspect damage.
- Distance from heat and sun. Heat thins the oils in an automatic and shortens battery life in a quartz. Sunlight fades dials in both.
- Somewhere consistent to rest. For an automatic, resting crown-up overnight often corrects a watch that runs slightly fast — gravity acts on the balance differently in each position. For a quartz it changes nothing, but the case and strap benefit either way.
If you own both
Most people end up with a mix, and the mix is where a rotation becomes a habit rather than a chore. The practical answer is to keep them visible: watches you cannot see are watches you do not wear, and an automatic that is never worn is an automatic that is always wrong.
Four watches fit on a Display Rack Four; six on the Summit. Two live comfortably on a Duo.
The one-line version
Wear the automatic or accept resetting it, never set the date at midnight, and change the quartz battery early with a new gasket. Everything else is preference.
