hello, I am a fairly new watch collector.  Right now I have an interest in Girard Perregaux watches.

[Collector]

I am seeking knowledge of who is best qualified to work on Girard Perregaux Gyromatic watches"  I have three; one from each generation which I would like to have regulated.

Not me. I've only worked on one.

one of the minor problems with this description is its broad. In other words I believe there were some variations including a high frequency version. The high-frequency version requires some one with knowledge of that as it has special characteristics for servicing

then the problems regulation is why does it need to be regulated? In other words watch so is made in the approximately 60 is it's never been serviced regulation will not fix any problems so basically I suspect which are really seeking a somebody to service your watch. Then you basically just need someone who likes to service vintage automatic watches with the high-frequency one as I said requiring some knowledge or preferably the technical sheet.

I had one of the highly advertised watch firms fully restore my Gyromatic which is a Chronomatic model with date.  It gains a minute per day!I could not find from them if it had been serviced with the special lube required for the Gyromatic models due to their fast moving part, and if it had been regulated on the machine which records the beats per minute.  I am searching for a firm which is well kown for this expertise with Girard Perregaux Gyrommatic watches as I have two, and another with only an Automatic model.

Where are you located in the world?

 

While there was (is?) a special contraption for lubricating the escape wheels of 36,000 beat movements, I have never seen one in 25+ years as a pro in both the U.S. and Switzerland, nor heard of anyone outside of a factory using it. I have serviced many 36,000 BPH movements, and found that using epilame and modern Moebius 9415 lubricant works fine, and lasts for years. I'm not sure when 9415 came out, but I think it was after these high beat movements became common. Unlike more traditional lubricants used on the escapement (oils), 9415 is a grease, which is thixotropic, which means that it becomes fluid at the point of contact during motion.

 

If you had your watch professionally serviced by a competent watchmaker, they certainly regulated it using a timing machine. Who did you give it to? These tend to regulate very well, although the mainspring barrels are difficult to next to impossible to service as they are sealed, and new ones are very hard to find (and would have 50 year old lubricant in them anyway).
