Automatic watches are marvels of engineering, blending precision mechanics with timeless aesthetics. However, like any mechanical device, they are susceptible to issues over time. Whether it's losing time, stopping unexpectedly, or making unusual noises, problems can arise from wear, lack of servicing, or external damage.

At Steven Hale Watch Repair (SHWR), we specialise in diagnosing and fixing these issues, ensuring that every timepiece is restored to factory precision. In this article, we explore common problems with automatic watches and how SHWR expertly repairs them.

Understanding How Automatic Watches Work

Before diving into common issues, it's essential to understand how an automatic watch functions. Unlike quartz watches that rely on a battery, automatic watches use a self-winding mechanical movement powered by:

• A rotor that moves with wrist motion

• A mainspring that stores energy

• A gear train that transfers energy

• A balance wheel and escapement that regulate time

Since automatic watches have intricate parts working together, small issues can affect overall accuracy and performance. Let’s explore the most common problems and how SHWR resolves them.

1. The Watch Is Losing or Gaining Time

Why It Happens

A well-maintained automatic watch should stay within a few seconds of deviation per day, but if it's gaining or losing minutes or even hours, it indicates an issue. The most common causes include:

• Magnetisation – Exposure to magnetic fields from phones, laptops, or speakers can affect the balance wheel.

• Dirt or debris in the movement – Over time, dust and grime can interfere with precision.

• Worn-out components – Parts like the mainspring or balance wheel can degrade.

How SHWR Fixes It

At SHWR, we thoroughly inspect the movement using specialist timegrapher machines to diagnose accuracy issues. Depending on the cause, we:
✅ Demagnetise the movement using professional-grade equipment
✅ Disassemble and clean the movement in an ultrasonic bath to remove debris
✅ Replace worn-out parts and regulate the balance wheel for optimal precision

After servicing, we calibrate the watch to ensure it runs within brand-specified tolerances.

2. The Watch Stops or Runs Only for a Short Time

Why It Happens

An automatic watch relies on constant wrist movement to stay powered. If it stops unexpectedly, it could be due to:

• Insufficient winding – If the watch isn't worn regularly, the mainspring may not have enough energy.

• Mainspring wear or breakage – The mainspring stores energy, and if damaged, it won’t deliver power properly.

• Issues with the rotor or automatic winding system – The rotor transfers wrist motion to the mainspring, and if it's loose or jammed, the watch won’t wind effectively.

How SHWR Fixes It

Our technicians conduct a full movement check to identify the cause. We:
✅ Manually wind the watch to test mainspring efficiency
✅ Inspect and repair the rotor if it's misaligned or jammed
✅ Replace the mainspring if it's worn or broken

For customers who don’t wear their watch daily, we recommend using a watch winder to keep it running when not in use.

3. The Watch Makes Unusual Noises or Feels Loose

Why It Happens

If your automatic watch makes rattling noises or feels loose when moved, possible reasons include:

• A loose rotor – The rotor should move smoothly, but if it detaches or becomes unbalanced, it may cause a loud spinning sound.

• Loose screws inside the movement – Small screws can loosen over time, leading to internal damage.

• Shock damage – Dropping the watch can displace components, affecting accuracy.

How SHWR Fixes It

Our team performs a detailed movement inspection to detect any misaligned or loose parts. We:
✅ Tighten or replace the rotor if it's off-centre
✅ Check for and resecure loose screws
✅ Realign internal components if the watch has suffered shock damage

We also advise customers to avoid high-impact activities while wearing their watch, as strong shocks can affect delicate mechanisms.

4. Water Damage or Moisture Inside the Watch

Why It Happens

Even water-resistant watches can suffer from water damage if seals deteriorate or if the watch is exposed to extreme conditions. Common causes include:

• Worn-out gaskets – Rubber seals around the crown, case back, and pushers degrade over time.

• Improper crown closure – Leaving the crown slightly open allows moisture in.

• Sudden temperature changes – Going from hot to cold environments can create condensation inside the crystal.

How SHWR Fixes It

If a watch has water inside, immediate servicing is crucial to prevent rust. Our process includes:
✅ Carefully opening the case to remove moisture
✅ Cleaning and drying the movement using specialised equipment
✅ Replacing damaged components if rust has formed
✅ Replacing all gaskets and testing water resistance

We also perform pressure testing to ensure the watch remains properly sealed against future water exposure.

5. The Date or Chronograph Function Isn’t Working

Why It Happens

Many automatic watches feature date displays and chronograph complications. If these stop working, it could be due to:

• Incorrect date setting – Adjusting the date at the wrong time (e.g., between 9 PM and 3 AM) can jam the gears.

• Wear or breakage in the gear train – Over time, date discs and chronograph components wear out.

• Lubrication issues – Lack of oil in the movement can cause complications to stick.

How SHWR Fixes It

Our watchmakers examine the complication system and:
✅ Realign or replace date wheels if they are misaligned
✅ Reapply lubrication to ensure smooth operation
✅ Repair or replace damaged chronograph components

We always advise customers to adjust the date only when the hands are outside the danger period (9 PM–3 AM) to prevent damage.

6. The Watch Crown or Pushers Are Stiff or Loose

Why It Happens

The crown and pushers are essential for setting the time and date, but they can become:

• Stiff due to dirt or dried lubrication

• Loose from worn-out seals or internal damage

• Damaged from excessive force

How SHWR Fixes It

We diagnose the issue by:
✅ Cleaning and re-lubricating the stem and pushers
✅ Replacing worn seals for smoother operation
✅ Repairing or replacing damaged winding stems if necessary

Regular servicing prevents dirt build-up and ensures the crown and pushers function smoothly.
