A related matter? .........
I have a 16610 LV Sub with Asian movement which I'm pretty pleased with. It looses 2-3 minutes a day but, for the price - GBP66.00 delivered, I'm happy.
If I run it down so that I have to manually wind it, I have noticed that I can turn that crown indefinitely. I've certainly turned it 150 times out of curiosity!
In other words it seems to wind ok but I can't feel any pressure/tension to indicate that it has fully wound.
This was immediately more noticeable when I purchased a SeaDweller with a better quality Swiss ETA engine - and twice the price! Here I have a much more accurate watch (+/- 15secs) and after 15 or so winds I can feel the tension.
Has anyone else experienced this? Is it a correctable fault? Should I be concerned?
What is certain is that, since reading The Zigmeister's post today, I will certainly keep the winds to a minimum.
