You spent real money on an automatic watch. Now you want it to last. The good news is that mechanical watches are built to run for decades — some for generations — if you treat them with basic respect. The bad news is that most of the “watch care” advice online is either obvious or wrong. Here is what actually matters.
Daily Wear Habits That Extend Watch Life
The single most important thing you can do for your automatic watch is wear it. Automatic movements are designed to run. The oils inside the movement stay distributed when the rotor spins, the mainspring stays tensioned, and the gaskets stay compressed. A watch that sits in a drawer for months at a time will need servicing sooner than one worn regularly.
That said, what you do while wearing it matters. Avoid wearing your watch during activities that produce sharp, repeated impacts — golf, tennis, hammering. The shock from a golf swing travels straight through your wrist into the movement and can damage the balance staff or knock the hairspring out of alignment. Swimming is fine if your watch is rated for it. Typing is fine. Driving is fine. Just avoid the hard shocks.
When you take the watch off at night, set it dial-up on a soft surface. This position is the most neutral for accuracy in most movements. Avoid leaving it on its side near the edge of a nightstand where it can fall — a three-foot drop onto a hard floor is exactly the kind of shock that cracks a crystal or bends a hand.
Cleaning Your Watch at Home
You do not need special watch cleaning solutions. A soft, lint-free cloth — the kind you would use on eyeglasses — is all you need for daily wipe-downs. If your watch is water-resistant to at least 50 meters, you can rinse it under lukewarm tap water to remove sweat, dust, and skin oils. Use a soft toothbrush on the bracelet or case if grime has built up in the links or around the crown.
Never use chemicals, solvents, or ultrasonic cleaners on a watch at home. Ultrasonic cleaners can loosen gaskets and compromise water resistance. Chemicals can damage case coatings, especially on rose gold or PVD-treated surfaces. If your watch needs more than soap and water, take it to a professional.
For leather straps, wipe them with a barely damp cloth and let them air dry. Never submerge a leather strap. If you wear your watch in hot weather or while exercising, consider switching to a rubber or metal bracelet for those activities and saving the leather for cooler conditions.
The Crown: Your Watch’s Most Vulnerable Point
The crown is the only opening in the case, which makes it the weakest point for water and dust entry. Always push the crown back in — or screw it down, if your watch has a screw-down crown — after setting the time or date. Never operate the crown in water or with wet hands. And never pull the crown out while the watch is submerged, even by accident.
If your crown feels stiff or gritty when you turn it, do not force it. That grit is a sign that the gasket is drying out or that debris has gotten into the crown tube. Take it to a watchmaker before the problem gets worse.
When to Service Your Automatic Watch
The general recommendation is every three to five years for a full service, which includes disassembling the movement, cleaning all parts, replacing worn components, re-oiling, reassembling, and regulating for accuracy. This is the single most important investment in your watch’s longevity.
Signs that your watch needs servicing sooner: it is losing or gaining more than 15–20 seconds per day, the power reserve has shortened noticeably, the crown feels rough, or the watch stops intermittently even when fully wound. Do not wait for complete failure — catching problems early prevents expensive damage.
For Lucky Harvey watches, we recommend servicing every four to five years under normal wear conditions. Our automaton and chiming complications have additional moving parts that benefit from regular professional attention. Contact us directly for service recommendations specific to your model.
Storage When You Are Not Wearing It
If you rotate between multiple watches, a watch winder keeps your automatics running and ready to wear. Choose a winder with adjustable turns-per-day settings so you can match it to your movement’s specifications. Too many turns can cause unnecessary wear on the winding mechanism; too few and the watch stops anyway.
If you do not use a winder, simply let the watch stop. This is fine. Modern automatic movements are designed to stop and restart without damage. When you pick it up again, give the crown 30–40 manual winds to fully charge the mainspring before putting it on your wrist.
Store watches in a cool, dry place away from direct sunlight, strong magnetic fields (speakers, laptops, phone cases with magnets), and extreme temperatures. A dedicated watch box with individual compartments prevents watches from scratching each other.
Common Mistakes to Avoid
- Setting the date between 9 PM and 3 AM. During this window, the date-change mechanism is engaged in most movements, and forcing the date quickset can strip the gears. Always set the date outside this danger zone.
- Using the chronograph underwater. Even on water-resistant watches, the chronograph pushers are not always sealed. Pressing them underwater can let water into the case.
- Ignoring magnetization. If your watch suddenly starts running several minutes fast per day, it may be magnetized. A watchmaker can demagnetize it in seconds with a simple tool — this is not a serious problem but it does need attention.
- Storing a wet watch in a closed box. Always let your watch air-dry completely before putting it away, especially after swimming or heavy rain exposure.
