I'm a fan of radio-controlled watches as they keep perfect time and never need adjusting.
I also have much-treasured 30-year old Omega clockwork job which I have regularly serviced and is as good as new.
My friendly local watch repairer hates radio-controlled watches and refuses to touch them.
Working for a chemical company, there are certain areas on our plant where we cannot take anything that has a battery (watches, phones etc) due to risk of sparks so we are always on the lookout for reliable clockwork watches.
