I have a new Citizen Eco-Drive watch, a basic dive watch. So far, it seems to be reasonably accurate, perhaps a second or two a day, BUT yesterday I happened to take it off and store it in my desk drawer overnight and I noticed that it lost almost TEN SECONDS overnight. Stored elsewhere, it seems to be right on time again today. The only possible explanation I can think of is that in the drawer it was in reasonably close proximity to my computer tower (and right under a landline caller ID phone), and possibly a foot or so from my LCD monitor, but it's hard to believe any of these create a strong enough magnetic field that they would interfere with the watch. But if it isn't one (or more) of those, I am stumped. Thoughts would be welcome and thank you in advance.
