I have a preference for electro-mechanical watches rather than purely digital. Using these in a situation where transformers and similar devices (such as welding equipment) are being switched on and off I would expect, and noticed, occasional, brief watch stoppage thereby losing time. (The watch is a Lorus Luminex with a large luminous dial.)

Is it possible that SSB operation on 80m in particular would have the same effect? I'm testing this but with no conclusive results. 80m does trip some earth/ground leakage current circuit breakers near the shack.
