The complete service involves dismantling the movement piece by piece and cleaning the individual components. Specialists carefully examine every part of the movement and repair or replace worn or faulty parts.

Subsequently, the watch is reassembled from scratch and, where necessary, oiled and lubricated. Finally, the watch’s accuracy is tested and the movement is readjusted. The case is also completely dismantled.

Scratches are repaired, case and strap components are ground or polished and the angles finished and then thoroughly cleaned.

Before the watch is returned to the customer, it undergoes a final intensive testing phase which lasts several days. Only by going to these lengths can IWC guarantee that the watch will run accurately and remain water-resistant for years to come.
