Mine says Hi! I recently replaced the mainsprings in my two recently conditioned Omega bumper automatics, including this one. I have been running these two on a watch winder as a test for duration of run. I find that 8 hours on the winder gives me ~ 40 hours of stationary run. I'll be wearing this one more often now, owing to the fact I don't have to re-set the calendar each time I put it on. Eight hours on the winder, and 40 hours off the winder will do these no harm. This one I'll wear until after the New Year.
