But surely CW must regulate as part of their service too?
To service a watch properly my understanding is the movement must be dismantled, cleaned, oiled and reassembled and any worn parts replaced. As such it is an absolute requirement to regulate (and adjust as necessary) the watch after such a procedure. I have never heard of a proper service that doesn't do this. Without this you cannot check if the action (amplitude) is low/correct, or and whether the service and assembly was correctly done identifying and rectifying all problems.
In many cases of extreme wear/damage it's often cheaper to simply put in a replacement movement and then perhaps put any custom parts back on...regulation is again what any competent service centre would do because at the very least it can help confirm the movement is OK
I'm happy to be corrected by any watch repairers, but this has always been my experience and it was the first check Rolex Singapore did on my watch while I waited, it actually told them the action was low and there were probably parts that would need replacing (included). When they returned it they had timed it back to COSC standards, but mentioned they would be happy to fine tune it to my usage pattern for free after I had worn it for 2-4 weeks. Admittedly that was a long time ago now, but I doubt things have changed much.
