Time Regulation at RSC

[Rolex01]

Anyone had sent in their rolex watch for time regulation?

This regulation is to ensure that the watch runs according to COSC Standards.

The cost is free if your watch is still under warranty and did any folks here try out this service?

[seiko.citizen]

Even for watches not in warranty they will perform at their discretion. If service intervals are too far, they can refuse.

Regulation takes a couple of hours (ie. drop off, pick up later)
