Time for Service?

[teb1013]

About 2 months ago I got my first Rolex a 16233 DJ x series (1991) and love the watch but over this time it has been running about -14 spd. My only other automatic watch is.a Tudor Black Bay (ETA) which I rotate with the Rolex. The Tudor runs about +4 spd. The person from which I bought the DJ indicated that it was "serviced" two years ago, by a non-Rolex watchmaker. I have no paperwork on this. I have no reliable watchmakers anywhere near me, the nearest AD is about 30 miles away. Does 14spd require service, I assume so but I'm new to mechanical watches and would like to know if this is recommended. If so, should I send this to an RSC? Is using the AD in my area (fairly close at 30 miles) a good idea or should I send it to NY or even Dallas (which seems to be the fave in these boards). I don't like to spend 1K at this time, but I'm willing to do so if experienced people here think it is best to do. Thanks.
