Hello sifus, i have a few questions regarding taking care of your watches; my question are:
1.I always use "Autosol: Metal polish" to do the job with (a polishing machine)...is it correct??
2.Most of my collections are Orients, so they are mostly Crystal lens...can use the same material also?
3.I bought a Ultrasonic machine to clean some hard to reach place in the watch before...is it safe? Because from what i heard on-line, is a big Taboo. It might spoil the inner gears...is the vibration so strong??
4.Will washing your watch with hot water (not boiling but middle temp) spoil the oil ring??

Pls

do advice.....
