Have been wearing my 104 for maybe 6 weeks now. Every day. It has been rock solid except for winding. I normally don't hand-wind automatics, so this isn't such a big deal, but this SW200-1 feels very heavy to wind. It is not doing anything strange like spinning the rotor when I wind it. Could it be a tight gasket that makes it take a lot more force to wind than something like a seiko dress watch? Seems heavy even if the watch is unwound. To be clear, it feels very smooth and solid, it just takes more torque than I'd expect.
Also, simply wearing the watch seems to not be winding it full. Maybe that's just because ~12 hours mostly at the computer and a little driving just isn't enough to give it much more than about 24 hours of life?
