The watch is an Omega cal.601 from 1969 and I bought it about a half a year ago. The watch had this weird sound in between the pallet forks ticks, sounds a bit like a metall releasing tension, witch made me thinking its either the mainspring or the hairspring.
I've now disassembled the watch, cleaned all the parts, replaced the mainspring, oiled the jewels and put it back together.
I noticed that the hairspring sounded quite a lot then I tried spinning it without the escapement in place, do you guys think the sound comes from the hairspring? Can I correct it or must I buy a new one?
