Wow, didn't realize this would stir up a hornets nest.
First of all, a watch losing a couple of minutes a day is well beyond what can be regulated out using the regulator. It needs some attention-there's likely a lot more going on.
Second, calling any place "the best watch repair place" in the country is a pretty bold claim. Truth be told, I've sent work to someone who could probably legitimately take that title. He can fix things that NO ONE else can-I've seen him create parts for a unique watch based on nothing but a patent sketch. But, he also takes works only by referral and even at that picks and chooses what he wants to fix, charges about what he darn well pleases, and is currently running at about 2 years. Most of the best folks in industry are like this.
But, then, you don't need someone like that unless you have a Waltham 5 minute repeater with a broken hammer and a few other missing parts 
.
There are a lot of competent repair people around-get a referral and check for certifications/memberships if you must. The current Swiss certification is called SAWTA, although WOSTEP is an older one and honestly a Hamilton 992B is not so complicated that you really need someone versed in the latest and greatest. In a lot of ways, someone who does more business in older watches would get my business over someone who services Rolexes all day.
