luminor hand wind question.

[asadtiger]

hello to all friends here at TRF..I have yet to handle a Luminor in person and so do not know exactly how its very unusual looking crown-lock works..I'd really appreciate if someone could show pictorially how it is opened and whether the crown is still screwed down under thye lock device or is ut then only a push in crown..thnx a lot..

oh and also, which was actually my intention of asking, how easy/comfortable is it to have to wind your luminors that are hand-wound wuth that unusual locking device...is it a nuisance for hand wind models..thnx once again

p.s. I have seen a screw on it and am assuming it has to be unscrewed with a screw opener...I feel very childish with my lack of knowledge of this working
