If I have a 1999 Rolex GMT Master which has been kept in the bank vault for the last 4 years and only now taken out and used. Would I need to send it for servicing or anything? It runs fine and all, but I don't think its been serviced since it was purchased in 1999.
If yes, what's the average service cost I'll be expecting when I bring it to Rolex (don't wanna get a heart attack there). Thx
