Dickens Jewelers in Clinton did my Dad's watch. I just dropped off the GF's inherited Rolex LadyDate (1999) which was daily worn and never serviced but still about +/- 5 seconds a month.
Victor, the owner, said if sent to Rolex, they would want to replace crystal, crown, and polish it in addition to service. $1500 easily, maybe $2000. He's doing full service, light polish of crystal, no polish to case or bracelet (we like the light patina), plus the water proof and timing test for $800 to $900. He said a few weeks turn around.
Victor was a manager at Patek service, so he's the right guy, locally.
