A mechanical or quartz watch is not just an accessory. Inside the case are dozens – sometimes hundreds – of tiny components working in perfect coordination: gears, springs, jewels, oils, seals, and electronic parts. Over time, these parts:
Wear down
Lose lubrication
Get affected by moisture, dust, and shocks
Drift in accuracy
Without regular servicing and prompt repairs, even the best watch can start to run poorly, stop altogether, or suffer damage that becomes much more expensive to fix later. Good watch repair is preventative medicine for your timepiece.
Here are some of the most common issues watch owners face – and what they usually mean behind the scenes.
If your watch suddenly starts gaining or losing minutes a day, it’s a clear sign something’s wrong. For mechanical watches, it can mean:
Old or dried-out lubricants
Worn parts in the movement
Magnetisation
A shock that disturbed the delicate regulating mechanism
For quartz watches, it can point to a failing battery or electronic issue. In both cases, a proper watchmaker can diagnose and correct the problem before it becomes serious.
Does your watch stop overnight, or cut out even though you’ve wound it or the battery is relatively new?
Possible causes include:
A mainspring problem in mechanical models
Dirt or old oil causing excess friction
Loose hands interfering with each other
A failing quartz module
This is not something a quick “shake and hope” will fix. A proper inspection and repair will restore reliable performance.
Even a tiny bit of fogging is a red flag. It usually means:
The gaskets and seals are old or damaged
The crown or pushers are not sealing properly
The watch may have been exposed to water beyond its rating
Moisture inside a watch can rust the movement, stain the dial, and damage hands or lume. This is where a professional pressure test, resealing, and sometimes a full service is essential.
The crystal (glass) is your first line of defence. Over time it can get scratched or even cracked:
Mineral and acrylic crystals scratch more easily
Sapphire crystals are tougher, but can still chip or crack on hard impact
Replacing the crystal is a common, straightforward repair that can instantly refresh the look of your watch and protect the dial underneath.
Loose links, stretched bracelets, failing clasps, or damaged lugs all affect not just comfort but security. The last thing you want is a valuable watch slipping off your wrist. A good repair workshop can:
Tighten or replace pins and screws
Refurbish or replace the clasp
Refinish the case and bracelet with careful polishing or brushing
Done properly, this keeps the watch safe to wear while preserving its character.
Not all “repairs” are created equal. A true professional repair – especially for luxury watches – involves far more than changing a battery or giving the case a quick polish.
A serious watch repair centre will typically:
Inspect and diagnose
Open the case in a dust-controlled environment
Evaluate the condition of the movement, dial, hands, seals, and crystal
Perform timing tests and water-resistance checks (when relevant)
Disassemble the movement
Carefully strip the movement down into individual components
Check each part for wear or damage
Clean all parts
Use professional cleaning machines and solutions
Remove old oils, dirt, and microscopic debris
Replace worn components
Fit new parts where necessary – ideally original or high-quality equivalents
For luxury brands, this is critical to maintain value and performance
Reassemble and lubricate
Apply the correct lubricants, in the correct places, in the correct amounts
Rebuild the movement with precision
Regulate and test
Adjust for accuracy in different positions
Test power reserve, date change, and complications (chronograph, GMT, etc.)
Refinish and reseal
Clean or refinish case and bracelet if requested
Replace gaskets, test water resistance, and ensure everything is properly sealed
This level of service is what keeps a good watch running beautifully for years.
Handing over your watch to just anyone can be risky, especially if you own luxury or sentimental pieces. A general mall kiosk or non-specialist may:
Use generic parts
Skip critical steps in servicing
Over-polish the case and ruin sharp edges or original finishes
Lack the tools to test accuracy or water resistance properly
For collectors and anyone who truly values their watches, a dedicated, specialist workshop is the safer choice.
If you’re in Hong Kong – or you’re comfortable shipping your watch to a trusted expert – AG Watch Repair Hong Kong (agwatchrepair.com.hk) offers exactly the kind of specialised service that serious watch enthusiasts look for.
Instead of treating your watch like just another job, they approach each timepiece as a unique mechanical artwork. Whether you have a modern Swiss diver, a classic dress watch, or a complicated chronograph, the focus is on:
Expert diagnostics – identifying the real root cause, not just treating surface symptoms
High-quality parts – using correct or compatible components to protect long-term performance

For owners of multiple watches or higher-end pieces, having a go-to specialist like AG Watch Repair Hong Kong can make ownership far more enjoyable and stress-free.
There’s no one-size-fits-all answer, but here are general guidelines:
Quartz watches
Battery replacement every 1–3 years
Full service roughly every 5–7 years, especially if water-resistant
Mechanical watches (automatic or manual)
Full service every 3–7 years depending on brand, usage, and environment
Immediate check if you notice accuracy issues, moisture, or unusual behaviour
If your watch is regularly exposed to water, sports, heat, or shocks, more frequent checks are wise.
You can’t avoid all wear and tear, but you can definitely slow it down:
Avoid extreme temperatures and magnetic fields
Don’t operate crowns or pushers underwater unless the watch is designed for it
Rinse your diver’s watch with fresh water after swimming in the sea or pool
Store watches in a safe, dry place when not in use
Use a proper watch roll or box when traveling
These small habits can prevent expensive problems from developing.
In a world of disposable gadgets, a well-made watch stands out. It’s repairable, serviceable, and built to last – but only if you look after it and choose the right professionals when something goes wrong.
Whether your watch needs a simple battery change, a full movement overhaul, or cosmetic restoration, partnering with a dedicated specialist such as AG Watch Repair Hong Kong (agwatchrepair.com.hk) ensures your timepiece gets the respect and care it deserves.
After all, your watch does more than tell time. It tells your story. Keeping it running beautifully is worth doing right.
