Old electromechanical clock ticking "yantar'". Electromechanical watches "amber", orlovsky watch factory, were made in 1977, the housing is made of wood, quartz movement. --recorded mono with sennheiser mkh40.
Taped a pair of jrf c-series contact mics on a small, very quiet wristwatch to see if i could get a good signal. Pleasantly surprised by the result. Removed the quartz hum and de-noised in rx 7.
