Watch service – movement disassembly
When I receive a timepiece for a watch service, I remove the movement from the case. Then I remove the dial and hands. Next, we disassemble the movement. When removing parts, we inspect them for damage or wear. I also like to make some adjustments and repairs now to reduce handling after cleaning.
Satisfied that all parts are serviceable, they go through our Elmasolvex VA cleaning machine which uses solutions that remove old oils and grease. It also has ultrasonic and vacuum technology to ensure optimum cleaning throughout.
We then lay out the parts on the bench and the bearings are cleaned using Pegwood. This is to ensure they are perfectly clean and now we start the re-assembly process.
Watch service – movement re-assembly
The very first stage of putting our movement together is to assemble, lubricate then check the winding and setting mechanism.
We then fit the barrel, train wheels and bridge. Now we have a ticking movement, we test it on the timing machine to ensure that it is running well.
Now we assemble and lubricate components that are for chronograph function and test them.
The last stage is to assemble, lubricate and adjust the date work
At this time, I check the watch on the timing machine again, both with and then without the chronograph running.
We fit the dial and hands, then test chronograph functions and adjust as required. We now case up the movement and use the timing machine to check regulation. Finally, we place it on the rotation machine.
