I had Bob Piker service my old Accutron 214. I've had it since new in the 1960's, and it had only been serviced once during that time. So, on the recommendations I found on a watch forum, I sent it off. I also had him convert it to a Spacewiew. Not only did I get it back sooner than expected, his work is stellar! Only Bob will be servicing my Accutrons in the future!
