Ideal for watches that are running well but are due routine maintenance, minor regulation, battery replacement or water-resistance renewal.
Best for:
Watches with no major performance issues that need preventative care.
Complete Service
A full overhaul of the watch movement, recommended when a watch is losing time, has stopped, hasn’t been serviced for several years, or requires more detailed mechanical attention.
Best for:
Watches showing performance issues or requiring a full restoration of the movement.

Charles Martin Watch Co. follows a meticulous 12-stage process for watch servicing and, where necessary, specialist repairs. Our experienced team of watchmakers brings together over 90 years of combined expertise within the watchmaking industry. Using industry-leading equipment and techniques, we ensure every timepiece is serviced and restored to the highest standards. You can be confident that your watch is in expert hands with Charles Martin.
Stage 1 - Full diagnostic and service estimation.
The process starts with a full diagnostic of the watch. We check not only the aesthetics of the watch but the functions and the condition of the movement itself. An estimate for the watch service is then sent to the customer for approval.
Stage 2 - Case & Bracelet Separation
Once approved, our watchmakers will separate the case, bracelet and bezel from the watch movement. So that the different components can go to the correct department.
Stage 3 - Cleaning & Refinishing
The case, bracelet and bezel are then sent to our polishing room where they are either cleaned or refinished back to their original condition. Depending on the condition of the watch this can take just as long as servicing the movement and usually includes at least 8 stages per watch.
Stage 4 - Movement Disassembly
The watch movement will now be completely stripped down by the watchmaker.
Stage 5 - Assessment of components
Our watchmakers will meticulously inspect all 1 - 160 individual components of the watch for any wear or damage. These components will be replaced if necessary.
Stage 6 - Cleaning the movement
The watch movement is then placed in our ultrasonic watch cleaning machine for up to an hour. Here it will go through various washing and rinse cycles removing the microscopic particles of dirt dust and of course old lubricate.
Stage 7 - Reassembly of the case, bracelet and bezel
Once refinished the watchmaker will reassemble the watch case exchanging as many as 10 different seals.
Stage 8 - Water resistance testing
Three separate water resistance tests will be carried out to make sure that the watch is water resistant. These include a vacuum test, a water submersion test and lastly a condensation test which will detect the slightest amount of water vapour trapped inside the watch case.
Stage 9 - Reassembly of the movement
Once clean, the watchmaker will then reassemble and re-oil the watch movement. There are often as many as 50 oiling points, which must be oiled exactly to ensure the watch works to the manufacturer’s specification.
Stage 10 - Time calibration
The watch will then be brought to time ensuring it is in beat and any positional errors are averaged out.
A modern mechanical beats 672,000 times a day, or 28,800 times an hour or nearly 8 times a second. For the watch to be accurate to within 4 seconds a day, the watch cannot deviate from these 672,000 beats by more than 31 in a 24-hour period.
Stage 11 - Reassembly of the complete watch
The watch movement is then put back into the watch case.
Stage 12 - Quality control
Over the next 72 hours the watch is then rigorously quality controlled to ensure the watch is accurate, the functions work aesthetically correct and will be reliable for years to come.
You can expect a 2 year warranty on a complete, luxury watch service from Charles Martin.

FAQ's
How often should I service my watch?
Most manufacturers recommend a full service every 4–6 years to maintain performance and prevent wear. If your watch is losing time or hasn’t been serviced within that period, it’s worth booking in.
What’s included in a watch service?
We completely strip, clean, inspect, lubricate, and reassemble your watch’s movement, replacing any worn components and resealing the case to restore accuracy and water-resistance.
How do I know if my watch needs a full or partial service?
If it’s still running but losing accuracy, a partial service may suffice. If it’s stopped, moisture-damaged, or long overdue, we recommend a complete service for full reliability.
Can I send my watch by post?
Yes. We offer a pre-paid, fully insured postal kit. Once received, follow the instructions inside, package your watch securely, and we’ll handle the rest. You’ll receive confirmation once your watch arrives at our service centre.
