Hi Milius,
Welcome to TRF.
I can understand the hands replacement bit, but the crown replacement bit is a lot of
Under any normal service, the crown of any Rolex HAS to be replaced. After all, the crown is fitted with the waterproofing seal inside. This seal then presses against the outer stem of the watch to create a hermetic seal against all the elements.
It is, therefore, mandatory for Rolex to replace any and every crown of each and every model at time of service. Therefore, the crown replacement cost should automatically come under the service coverage.
Cheers - JJ
