I've been scrutinizing my DW5600E for about 10 days now and came to a conclusion that the little boy gains a whopping half second a day.
If you are wondering if that may bother me yes,it really bothers me a lot. The radiocontrolled addiction got me truly addicted to up to the second precision . I mean,it's not a big deal if you think of it,it's actually the -/+ 15 seconds Casio talks about,but you know the feeling.
Nothing relevant to say about my new Mudoman,it just gained a second and a half in since I've got it 2 weeks ago. I really hope my incoming Mudman MX8 will be as much as consistent .
And the winner is .......the infamous F91W . Unbelivably consistent.
Now here is the main question ( of course the DW5600 case do not apply) : it's our non radiocontrolled watches that gain or lose or it's the atomic hour that update and change depending on the season/earth rotation or whatever it may be ?? Or maybe a mix of both things...
