Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsCare for a mechanical watch according to its specific model manual: wind and set it as instructed, clean only the case and strap materials the manual permits, protect it from water, strong magnets and impacts, and use an authorized service channel for checks or repairs. There is no single winding method or service interval that applies to every mechanical watch.
Wind and set it according to its movement
Manual-wind and automatic watches do not necessarily use the same winding routine. Follow the instructions for the exact model and caliber, especially when restarting a stopped watch or setting its date and calendar.

Automatic watches
Automatic watches wind through wear, but some manufacturers advise manually winding a stopped watch before wearing it. Their instructions differ: TAG Heuer gives roughly 30–40 crown turns or until the seconds hand starts for its stopped automatics, while Patek Philippe describes using a few gentle turns. These are brand-specific directions, not a universal rule for every automatic movement. See TAG Heuer’s care guidance and Patek Philippe’s watch-care advice.

Wind a manual watch as its instructions describe, stopping when you reach the indicated resistance. Audemars Piguet and Cartier caution against forcing the crown at the end of winding. If the crown resists unexpectedly, do not try to overcome it; consult the model manual or an authorized service provider.

Date and calendar setting
Some movements restrict when the date or calendar can be adjusted. Check the watch’s instructions before changing these settings; do not assume that a procedure for one watch is safe for another.
Clean the case and strap without risking damage
Routine external cleaning
A soft, clean cloth is a low-risk choice for wiping the watch. Hamilton recommends periodic cleaning with a soft, dry cloth, and TAG Heuer names a microfiber cloth for surface care. A cloth does not require exposing the watch to water.

Water, soap or a soft-bristled brush may be suitable for some water-resistant cases and metal bracelets, but manufacturer instructions vary. Junghans and Hamilton describe soapy-water cleaning for certain metal straps and water-resistant cases; TAG Heuer describes gentle cleaning with a soft-bristled toothbrush dipped in warm water while cautioning against immersion. Use these methods only if the exact watch’s case construction, water-resistance condition and manual permit them. Avoid cleaners or soap where the manufacturer warns they can leave harmful residue. Brand guidance is available from Hamilton, Junghans and TAG Heuer.
Recommended Free Tools
Leather straps
Keep a leather strap away from water and excess moisture; Patek Philippe, Cartier, Hamilton and Junghans warn that moisture can contribute to wear, discoloration or deformation. The applicable manufacturer may also advise avoiding cosmetics and prolonged sunlight. Follow the strap maker’s or watch maker’s care instructions rather than applying a bracelet-cleaning method to leather.

Treat water resistance as a condition that can change
Water resistance can decline as seals age or after an impact. A case marking or the general phrase “water resistant” does not, by itself, establish that a particular watch is suitable for swimming, showering or other water exposure. Check the model manual and case marking, and make sure the crown is fully returned or screwed down as directed. Several manufacturers advise against operating the crown or pushers underwater.
Sweat, chlorine, salt water, cosmetics and temperature changes may affect seals. Avoid hot showers, saunas, steam and abrupt temperature changes where the manufacturer advises against them. If the watch is rated for the exposure and its instructions permit it, rinse off salt water or pool water with clean fresh water afterward.

Arrange water-resistance testing through the brand’s authorized service channel. The suggested checks vary: Junghans and Hamilton recommend annual checks, while TAG Heuer advises testing every two years for watches regularly exposed to water. These schedules are manufacturer guidance, not one universal testing rule. See Junghans, Hamilton and TAG Heuer.

Keep the watch away from strong magnetic fields, including those from speakers and some electronic devices. Magnetism can affect timekeeping. If the watch begins running unusually fast or slow after possible magnet exposure, ask a manufacturer service center or boutique to assess it; the service provider can determine whether demagnetization or another repair is appropriate.

Impacts can damage a watch and may compromise water resistance. If it has suffered a significant knock, or its timekeeping changes unexpectedly, have it assessed rather than assuming that the case and movement remain unaffected.
Choose service timing by brand, service type and condition
There is no universal mechanical-watch overhaul interval. Published brand recommendations differ and apply to those manufacturers’ watches, not to the industry as a whole.
| Manufacturer | Published guidance | What it applies to |
|---|---|---|
| Seiko Watch Corporation | About every three years | General recommended service interval for Seiko watches. Source |
| TAG Heuer | About every five to six years | Approximate overhaul interval for TAG Heuer watches. Source |
| Patek Philippe | Every eight to ten years | Recommended interval for its manually wound and self-winding mechanical watches. Source |
| Junghans | Four to six years | Suggested service or overhaul interval, depending on use. Source |
| Hamilton | No fixed universal interval | Hamilton says timing depends on model, climate and care. Source |
Do not confuse a water-resistance check with a movement overhaul: they are different services, and water-resistance testing may be due more frequently if the watch is regularly exposed to water. Seek professional assessment sooner if the watch malfunctions, suffers an impact or develops a timekeeping problem. Use the manufacturer’s service channel for the specified checks and repairs.
