I will of course check the winding issue (thanks to all for the advice). I want to wear it a lot but have many watches and also a lange 1815 Anniversary 200 Years F.A. Lange (40mm in Platinum) as I did parted with my Lange 1 yellow gold. I think the Zeitwerk would be a great addition to a great 2 watches lange collection. I hope is not monstrous heavy but from what I recall the gold oen was not super heavy.
