Hi everyone, was super delighted to see how responsive this community is... I am resolving the 1st issue with my Slava watch and now I am confident I can get some help with my Molnya 3602 -I took it apart and noticed the balance spring is a little uneven and does not go back and forth... I took the bridge off (one screw) took out the balance wheel and spring attached but did not see anything wrong, out it back and the same issue pessimists. I need help understanding if the balance wheel is properly installed and / or needs replacement to get the mechanism to function. checked all other parts and main spring is good. Would help if I can also find the front crystal/glass and an authentic face.

Hello, This Girard-Perregaux watch (21 Jewel, calibre 03B) runs fine in dial up position, but will start to sputter and sometimes even stops as it is rotated to dial-down position. I looked closely at the hairspring balance shaft and noticed one of the ends looks eroded and short. I am hoping to replace the balance shaft with a new one which I have purchased from the Netherlands (vacheron seller on ebay). Now, what I am seeking in posting this is help with: 1) Confirmation of the need to replace the balance shaft judging from the pictures-- 2) Can I perform the balance shaft swap without a staking set and poising tool? P.S. I looked up some info, and I know I have to mark on the balance wheel before I remove the roller table and jewel Thanks very much in advance for any information. JC
