I am a newbie in watch repair. Recently bought a zim 2602 watch, it produces strange noise, and stops. The volume of the noise depends on the position of the watch, tends to stop rather in face up position. My guess was that the hairspring touches something, but I wasn't able to prove that visually. I attach a file about the sound it makes and a pictures. Thank you any help.
D2 highly sought after machine in the US. Probably elsewhere too. Nice small tractor for play and stump pulling.
I grew up around D8 14A2180. I remember the serial after all these years! Dad dropped my 1899 Waltham on the tread plate and broke the balance. Took 30 years for me to get it rebuilt.
