I bought my wife a Reverso Gran' Sport in 2001 and had it engraved by JC Randall who was JLC's authorized American engraver (now retired), but she stopped wearing it a few years ago so I thought it was about time to get it overhauled and put back in good condition. It was a pretty seamless service from JLC in Dallas, you put in the serial number on their system and it comes back with the estimated cost. They even include insured FedEx shipping both ways. Total cost was $650 (plus state tax) and took about eight weeks, a fair price and turnaround in today's world. They did a really good job and they cleaned up the case as it had acquired a fair about of scratches over the years.
