Automatic Watch Maintenance: Tips to Protect Your Investment

An automatic watch is a finely crafted timepiece that requires regular care to ensure precision and longevity. Proper maintenance includes regular wearing, gentle cleaning, and safe storage to prevent damage.

Servicing is essential to keep the movement running smoothly, but is it worth it? Absolutely—neglecting service can lead to costly repairs. Signs that your watch needs servicing include inaccurate timekeeping, unusual noises, or a stiff crown.

Lubrication is typically required every 3–5 years to prevent wear. In this automatic watch maintenance article, we’ll cover simple yet effective tips to keep your automatic watch in excellent condition for years to come.

Overview of Automatic Watches

Automatic watches, also known as self-winding watches, are mechanical timepieces that don’t require manual winding or a battery like quartz watches do. Instead, they harness the motion of the wearer’s wrist to wind the mainspring, which powers the watch.

This is achieved through a rotor, a semicircular weight that moves with wrist movements. The rotor’s motion transfers energy to the mainspring through a series of gears, storing energy and keeping the watch running.

Proper maintenance is essential to ensure the longevity and accuracy of an automatic watch. Over time, lubricants inside the movement degrade, and components may wear down, affecting precision. Regular maintenance helps prevent mechanical issues, preserves movement efficiency, and keeps the watch functioning optimally for years to come.

Here are some simple mechanical watch maintenance pointers to keep your prized investment in top condition:

1. Have an Expert Apply a Watch Protective Film Over It

A watch protective film is a transparent layer designed to shield the surface of a watch from scratches and minor impacts. It’s optional but increasingly popular among collectors who want to avoid scratches. It can be applied to various parts of the watch, including the case, crystal, and clasp. It ensures that the watch maintains its appearance and value over time.

Advantages of Watch Protective Film

• Scratch Resistance: The film prevents scratches, preserving the pristine condition of watches.
• Cost-Effective: It avoids frequent polishing or repair costs by protecting the surface.
• Aesthetic Preservation: It keeps the watch looking new, which is crucial for luxury timepieces.

Hiring a professional to apply a watch protective film offers significant benefits. Expert precision ensures the film is applied without bubbles or misalignment issues, which can detract from the watch’s appearance. Additionally, professionals have access to the necessary tools and experience to cover even the smallest and most complex surfaces, such as the bezel and lugs.

2. Wear Your Watch Regularly

Wearing an automatic watch regularly is essential to maintaining its performance and longevity. Since it relies on the motion of your wrist to keep the mainspring wound, consistent wear ensures that the power reserve remains charged, allowing it to function smoothly and accurately. If left unworn for extended periods, the watch’s automatic movement may stop, requiring manual winding to restart.

Avoiding Extreme Activities

While automatic watches are designed for durability, they should be protected from extreme conditions. Intense sports or sudden shocks can affect the movement, potentially causing misalignment or damage. It’s best to remove the watch before engaging in high-impact activities to preserve its accuracy and mechanical integrity.

Proper Manual Winding

Although an activated rotor makes an automatic watch wind itself, you may need to wound it manually to maintain its function if you don’t wear it daily. Almost every mechanical watch has the same basic architecture, so here’s how you manually wind it:

• Unscrew the crown (if applicable): Some watches have a screw-down crown for water resistance. Unscrew it carefully before winding.
• Turn the crown clockwise: Typically 20-40 turns, depending on the movement. This helps wind the mainspring sufficiently.
• Set the time (and date): If the watch has stopped, set the time and date correctly before wearing it.
• Secure the crown: If your watch has a screw-down crown, ensure it is properly tightened to maintain water resistance.

3. Clean it Using the Recommended Methods

Cleaning an automatic watch requires attention to detail to ensure it remains in good condition.

Recommended Cleaning Methods

Step 1: Remove the Strap (if applicable)

If the watch has a leather or fabric strap, detach it to clean separately. These materials should not be exposed to excessive moisture.

Step 2: Dry Cleaning (for Non-Water-Resistant Watches)

• Use a dry microfiber cloth to wipe the case, dial, and back.
• Use a soft-bristled brush or a cotton swab for dirt-prone areas.
• Avoid using water or cleaning solutions on non-water-resistant watches.

Step 3: Light Cleaning with Damp Cloth (For Water-Resistant Watches)

• Slightly dampen a cloth with mild soap and water.
• Gently wipe the case, avoiding the crown and other openings.
• Use a brush to clean crevices, but do not soak the watch.

Step 4: Deep Cleaning (For High Water-Resistance Watches)

• If your watch has a high water resistance rating (100m+), you can briefly rinse it under lukewarm water. Always ensure crown is fully screwed down before cleaning.
• Avoid prolonged exposure to running water.

Step 5: Drying

• Use a dry cloth to remove moisture.
• Let the watch air-dry for a few minutes before wearing or storing.

Checking Water Resistance Rating

Water resistance ratings determine how much exposure your watch can handle. Here’s how to interpret them:

Rating	Water resistance level	Safe activities
30m (3 ATM)	Splash resistant only	Handwashing, light rain
50m (5 ATM)	Light water exposure	Showering (not recommended)
100m (10 ATM)	Suitable for swimming	Swimming, snorkeling
200m+ (20 ATM)	Suitable for diving	Scuba diving, professional water sports

Best Materials for Drying After Cleaning

• Microfiber cloth: Absorbs moisture without scratching the surface.
• Lint-free cotton cloth: Ideal for drying metal bands and watch cases.
• Soft air blower: Helps remove moisture from small crevices.
• Silica gel packets: Can be used to absorb moisture if the watch gets slightly wet.

4. Store it Properly When You’re Not Wearing It

When an automatic watch is not in use, storing it correctly and under the right conditions is crucial. Some of the most common storage accessories you can use are:

• Watch box (best for short-term and occasional use)
• Watch Winder (useful for convenience with complicated watches, but not essential for simple 3-hand/date models)
• Soft pouch (best for travel or minimalist storage) – ensure the watch is completely dry before placing it in a pouch to prevent moisture buildup

Effects of Temperature and Humidity on Automatic Watches

Watches are precision instruments and can be affected by extreme temperatures and humidity.

Temperature Effects

• Extreme Heat (>50°C / 122°F): Can cause lubrication inside the movement to break down, affecting accuracy and longevity.
• Extreme Cold (<0°C / 32°F): Can cause oils to thicken, leading to increased friction and reduced accuracy.
• Rapid Temperature Changes: Can lead to condensation inside the watch, potentially damaging internal components.

Humidity Effects

• High Humidity (>70%): If moisture enters the case, it can cause rust on internal components, especially if the watch is not water-resistant.
• Low Humidity (<30%): Dry environments can cause seals and gaskets to dry out, reducing water resistance over time.

Tip: Store watches in a controlled environment (40-60% humidity, 15-25°C) and use silica gel packs to absorb excess moisture.

Why and When to Use a Watch Winder

A watch winder is useful for certain types of automatic watches but isn’t necessary for all.

When to Use a Watch Winder

• If your watch has complicated functions (perpetual calendar, moon phase, multiple time zones) that are tedious to reset.
• If you wear your watch infrequently but want it to be ready to wear without resetting.
• If the manufacturer recommends continuous operation for optimal performance.

When NOT to Use a Watch Winder

• If your watch is simple and easy to reset (time and date only).
• If you don’t plan to wear the watch for an extended period.
• If your watch has a power reserve long enough to last between wears.

Tip: Use a watch winder with settings that match your watch’s specifications (TPD and rotation direction) to avoid overwinding and unnecessary wear. Please note that watch winders don’t prevent wear; they actually cause slightly more wear because the movement runs constantly.

5. Have it Serviced (and Repaired) Regularly by Professionals

Manufacturer-Recommended Service Intervals

Most luxury and high-quality automatic watch brands recommend servicing at regular intervals to keep them running smoothly. Here’s a general guideline based on brand recommendations:

• Rolex: Every 5-10 years, depending on wear and environment.
• Omega: Typically every 5-8 years.
• Tag Heuer: Every 5-7 years.
• Patek Philippe: Every 3-5 years for complex complications.
• Seiko: For premium Seiko mechanical watches, service every 3 years. For entry-level models, service only if issues arise.

Other Signs Your Watch Needs Servicing

Aside from the signs provided earlier, here are other indicators that your watch may require servicing:

1. Power Reserve Issues

• Runs out of power too quickly, despite being fully wound.
• Doesn’t hold its advertised power reserve duration.

2. Moisture or Condensation Inside the Crystal

Fogging or water droplets inside the dial indicate a compromised seal.

3. Physical Damage

Broken or misaligned hands, loose markers, or visible wear on the caseback.

4. Seconds Hand Skipping or Stuttering

A mechanical watch should have a smooth sweep. An erratic motion suggests movement wear or escapement issues.

How to Find a Reliable and Certified Watchmaker

When your automatic watch needs servicing or repair, it’s crucial to select a qualified professional. Here’s how to ensure you get your watch serviced by an expert:

1. Look for Manufacturer Authorization

Many brands have authorized service centers (e.g., Rolex Service Centers and Omega Boutique Repairs). Officially certified watchmakers have direct access to genuine parts and manufacturer specifications.

2. Check Certifications

Look for certifications such as WOSTEP (Swiss Watchmakers Training & Education Program) – Swiss-certified training.

3. Read Reviews & Ask for References

Online reviews, forums (e.g., Watchuseek, TimeZone), and word-of-mouth recommendations can help determine credibility.

4. Request a Warranty on Repairs

Reliable service centers provide a warranty (often 1-2 years) on repairs and maintenance.

5. Assess Transparency & Communication

A professional watchmaker should explain the required repairs, estimated costs, and expected turnaround time.

6. Set the Time and Date Properly to Avoid Damaging the Movement

Avoid Adjustments During Restricted Hours

Many mechanical luxury watches, especially those with a date complication, have an internal mechanism that engages from 9:00 PM to 3:00 AM (Check your watch manual for exact restricted times, as it varies by movement). During this period, the gears responsible for advancing the date are in motion. Manually changing the date can cause damage to the date wheel, gears, or the quickset mechanism.

Best Practice:

• Set the time outside the restricted period (ideally between 5:00 AM and 8:00 PM).
• If unsure, move the hands to 6:30 AM or PM before adjusting the date.

Setting the Date Properly

If your watch has a quickset date function (where the crown has a dedicated position for changing the date), use it only outside the restricted hours. If the watch lacks a quickset feature, advance the hands forward (not backward) past midnight to change the date naturally.

Setting the Time Safely

• Hack the movement (if applicable) – Many watches stop the seconds hand when the crown is pulled to the time-setting position, allowing for precise time setting.
• Turn the hands forward whenever possible instead of rotating them backward.
• If you must adjust backward, do so cautiously and only for a small amount (a few minutes).
• If adjusting the time near midnight, be extra careful not to disrupt the date-change mechanism.

7. Avoid Common Mistakes

• Don’t overwind the watch when winding it manually. Manual winding isn’t needed daily unless the watch stops or you rotate watches often. This prevents damage to its delicate mechanics and enhances durability.
• Don’t place your automatic watch near electronics or strong magnets, like smartphones and laptops. These can magnetize the watch’s components, leading to inaccurate timekeeping.
• Don’t misuse chronographs or other complications as it can also lead to mechanical issues. Engage them only as intended and avoid unnecessary activation, which may strain the watch’s movement.

Final Word

Proper maintenance ensures your automatic watch remains accurate and lasts a lifetime. Regular winding, cleaning, and servicing prevent wear and tear. Store it safely, avoid extreme conditions, and seek professional care when needed. With diligent upkeep, your timepiece will continue to function beautifully, preserving its craftsmanship and reliability for years.
