From the moment your watch arrives at one of the worldwide IWC Service Centres, it is handled with the same precision and detailed attention that it was given when first built. In the certified Complete Service (comprised of 16 steps and recommended every 5 years), skilled watchmakers dismantle, clean, repair, and reassemble every component in the watch. But that is just the quick description.The truly unique service procedures include the removal of the watch movement from the case, and then a full dismantling of the movement's many components. As seen here, this is no easy feat and requires extremely steady hands and immense dexterity.
