Hi everyone. I wonder if someone can help me. I am just a beginner and new to the site but reading through some of the threads have been amazed how helpful everyone is.
I have a 50's Universal Geneve wrist watch with a 263 movement which had stopped and needed a thorough clean. I have fully disassembled it but realise now I probably did not need to take off the upper (watch face side) balance pinion jewel plate with the lyre spring, just to clean the capstone and jewel!
Anyway, whilst struggling to reassemble this section, the lyre spring (pictured before escape) made a successful break for it and is lost to the world forever. Could anyone please tell me how to find another of the right size to fit? I know Cousins sell them, but do not know how to relate their ETA sizes to UG movements. Is there a conversion list somewhere?
Hugely grateful for any assistance.
Best regards
Jon
