New seriel number assignment on a 1680 overhaul?

[mask1196]

Hi all,

My title probably sounded extremely weird. Let me elaborate a bit on the scenario and my actual question.

I brought in a 1680 Submariner into Rolex NY for a full service. On top of the full service, I also purchased a complete set of case (case frame, bezel, bezel insert) to replace the existing one that's been heavily polished down. The 1680 is a 5.4 mil series, upon asking how the purchase of a new case would affect the original seriel & model number that's already engraved on both ends of the watch case, I was told that a "different" seriel number will come onto the new watch case I'm getting. This really bothered me as I was not aware of such practice by Rolex and I can just tell this would only devalue my 1680 that came with complete paper work from '78 when I took it over. More importantly, what kind of seriel number am I getting assigned to my watch now?

What should i do?
