Mechanical Watch Servicing

Checklist

Our expert watchmakers perform an in-depth series of checks to make sure your timepiece returns to you in tip-top condition:

1. Check the case and the bracelet or strap.
2. Detach the bracelet or strap, open the case and remove the stem, crown, seals and movement.
3. Reset the stem and crown, and check the winding mechanism.
4. Examine the working of the hands, calendar functions and rotor, if fitted.
5. Inspect and adjust the escapement.
6. Fully disassemble the case and inspect the movement and parts.
7. Replace any worn or damaged parts.
8. Carefully clean all the parts in specialist chemical baths, using automated cleaning machines.
9. Reassemble the movement, fine-tuning it in line with brand specifications.
10. Lubricate the movement, if using fine oils and greases, and check the escapement.
11. De-magnetise, regulate and check the timing of the movement to brand standards, using specialist Swiss timing equipment.
12. Refit the dial and hands, and clean the case and bracelet using ultrasound technology.
13. Replace the case seals, if necessary, and refit the movement and bracelet or strap.
14. Check the timekeeping and adjust it, where required, using timing equipment.

Once we’ve completed these steps, we test the timepiece on a wrist simulator for three to four-and-a-half hours to make sure the automatic winding system is running smoothly. The watch’s power reserve is then tested statically for 24 hours, dial down, and the rate checked, until the power has run down in the dial up position. This final inspection before we return your watch to you is critical, because, after that, it’s guaranteed for 12 or 24 months, depending on the brand.
