Girard-Perregaux Cal. 19 service

[LittleWatchShop]

OK, nothing too exciting here but I wanted to post something to show I am progressing...lol.

This belongs to a friend of mine...a guy that used to work for me.  It was his grandfather's watch and he was very close to him.  When my buddy found I was doing watches, he asked me to fix it (along with three other watches!).  This was the most interesting.

The service was uneventful except for a busted mainspring.  I found one on ebay from a guy have bought from several times before--a good vendor.  Now, this is an automatic, so I used my YamaLube for the breaking grease.  However, since this is a NOS modern mainspring, I did not do any additional oiling.  This may be controversial as some say they come lubricated and others may disagree.  We shall see.

I had some trouble putting the clip on the oscillating weight.  At first, I did not see that the arbor had to be aligned to the kerf in the weight.  It was rather difficult to see!  The microsope revealed the truth. 

The case ring was quite unusual as it had the gasket embedded in it--something I had never seen before.  It was old and dried up and flaked into the workings of the watch.  I had to thoroughly remove the residual gasket material.  I did not replace the gasket so will warn my friend that it is not going to be waterproof.

It is running and keeping good time.
