Yes. As said above wind it till you feel resistance/stop. It's not really possible to over-wind an manual, unless you really tried to force it. Just wind it once a day at around the same time.Loving my new used Steinhart!! What is correct way to wind the manual Nav B-Uhr II? Is there a certain number of turns or is it done by feeling? I'd like it to run for 24 hours without winding again, is that possible?
