I've been searching the old posts -- is Beacon Jewelers in M'pwd Village still alive? Also, what about the jeweler (old man?) on 1581 Springfield Avenue?
edited to add that I need a battery put inside of a running watch that's very difficult to open.
The Jeweler on Springfield (and he's old in years but not in spirit - he's an amazing guy) is the one I recommend without hesitation. His name is Joe Lancieri and his phone number 973-761-0017.
Mr. Simpson is one of several watchmaker's that reside in the Newark Jeweler's Supply building across from the new Maplewood police station, all are reliable.
