Movement expertise for the world's finest watches.
When a luxury watch stops keeping time, the cause is rarely simple. Worn pivots, tired lubrication or a damaged escapement each leave a different trace. Accorn Chronos Ltd reads those signs carefully and repairs the movement with technical rigour and personal attention.

The right diagnosis matters
Movements we service
Every calibre has its own habits, tolerances and failure points. We test before we open the case.
Automatic
Rotor bearings, reversing wheels and winding efficiency are checked during automatic watch servicing.
Discuss your watchQuartz
We test the circuit, coil and train, then source suitable components when a replacement is needed.

Column-wheel and cam-actuated systems need exact timing. We handle stopwatch, reset and clutch faults in-house.

From diagnosis to reassembly
Good repair starts with evidence. We document the movement, explain the options and keep approval in your hands.
Book a Movement Assessment01
Diagnostics
Timing-machine readings, visual inspection and water-resistance testing establish the fault. Checkpoint: the symptoms are recorded before disassembly.
02
Disassembly
The movement is broken down and each component is documented. Checkpoint: parts are labelled and protected as the architecture is recorded.
03
Cleaning
Ultrasonic cleaning removes old lubricants and contaminants from suitable components. Checkpoint: jewels, pivots and teeth are inspected after cleaning.
04
Repair and sourcing
Worn parts are repaired or replaced with original or sympathetic components where appropriate. Checkpoint: no part is fitted without your written approval.
05
Reassembly and lubrication
The movement is rebuilt with the correct modern lubricants at each pivot and contact point. Checkpoint: winding and setting functions are checked as the work progresses.
06
Testing and regulation
Multi-position timing tests and final adjustment follow reassembly. Checkpoint: the watch leaves only after its readings settle within an agreed tolerance.

- Water-resistance re-certification follows case closure, with documentation provided.
- Final magnified inspection confirms clean surfaces and correct finishing.
