When your beloved timepiece stops ticking—or worse, starts running fast, slow, or not at all—it’s tempting to panic. But bringing it in for a watch repair service isn’t the end of the world; in fact, it’s a chance to restore its precision and extend its life.
Luxury or everyday, mechanical or quartz, your watch is more than a timekeeper—it’s an engineering marvel. And when something so intricate falters, it takes expert hands, the right tools, and a well-oiled process (literally) to bring it back to form. Here’s what really goes on behind the counter when you drop off your watch for repair.

Detailed Breakdown
Step 1: Initial Diagnosis & Intake
The journey begins at the counter. A technician or certified watchmaker inspects your timepiece for obvious issues—cracks, condensation, misalignment, or wear.
They'll ask questions like:
-
When did the problem start?
-
Has the watch been opened or serviced before?
-
Is it still under warranty?
This helps them flag whether it’s a routine fix or a deeper mechanical issue.
Step 2: Full Disassembly & Assessment
Once your watch enters the repair workshop, it’s photographed and cataloged. Then, it’s fully disassembled—down to the last gear, jewel, and screw. This step is critical for mechanical watches, where dozens (or hundreds) of tiny components can affect performance.
Each part is examined for:
-
Wear and tear
-
Rust or corrosion
-
Broken or loose pieces
Quartz watches might undergo electronic diagnostics to check circuit functionality and battery health.
Step 3: Ultrasonic Cleaning
No toothbrushes here. Watchmakers use ultrasonic cleaning machines to remove microscopic dirt, dried oils, and metal debris from each component. The result? A spotless movement that’s ready to be reassembled.
Clean parts reduce friction, which in turn improves accuracy and prevents future damage.
Step 4: Repairs, Replacements, and Oil
Next, damaged parts are replaced—always with manufacturer-approved or original parts when possible. For vintage watches, custom fabrication or vintage part sourcing might be necessary.
Then comes re-oiling. Watchmakers use synthetic lubricants with pinpoint accuracy to reduce friction and extend the life of the movement.
Step 5: Reassembly and Regulation
The cleaned and serviced parts are carefully reassembled, and the watch is tested for function. Mechanical watches are regulated to ensure accurate timekeeping, often using a timing machine that measures beats per hour.
For quartz models, the battery is tested or replaced, and the circuit is rechecked.
Step 6: Final Testing and Quality Assurance
Before the watch is returned, it undergoes several tests:
-
Water resistance testing (for sealed models)
-
Time accuracy monitoring over 24–72 hours
-
Power reserve check
-
Visual and tactile inspection
Some high-end repair shops simulate real-world conditions to ensure the watch holds up to daily wear.
Step 7: Ready for Pickup—with Peace of Mind
Once all checks are complete, the watch is polished (if applicable), cased, and returned with a repair summary. Most reputable service centers offer a 6 to 12-month warranty on repairs.
You walk out with more than a functioning watch—you get back trust in your timepiece.

FAQs
How long does a watch repair service usually take?
It depends on the issue and the type of watch. Battery replacements might take 30 minutes, while full mechanical overhauls can take 4 to 6 weeks, especially if parts need sourcing.
Is it worth repairing an old or vintage watch?
Absolutely—especially if it has sentimental value or is a high-end brand. Expert repairs can restore functionality and even increase resale value, provided authentic parts are used.
How often should I service my mechanical watch?
Most brands recommend servicing every 3 to 5 years. Even if it seems to be running fine, dried-up lubricants or unseen wear could lead to bigger issues down the line.
What’s the cost of a watch repair service?
Prices vary widely. A simple battery swap might cost $25, while a full mechanical overhaul can range from $200 to $1,000 or more, depending on brand and complexity.
Can water-resistant watches still get water damage?
Yes—especially if the gaskets are old or the case has been opened without resealing. Annual water-resistance testing is recommended if you swim or shower with your watch regularly.
