I have a watch Harry Denmark Sir, examined by a prominate watchmaker ( 40 years plus ), but when I (Forum),about it I keep constantly get that there is no difference's of the two. The case's appear the same, yet the movements are not. To find 6306 movement parts seem to be ......... " A Awesome Task ". The dial's are different from what I know, so they are differences but 6309's dont Hack, and 6306's do , right ? I know there is a kit, but the original 6306 is a hard item to find. 17 jewels are not 21 jewels or 23 jewels right ? But Seiko say there arent the same,so what on all this if I may ask about it to be on target.
But I have both I would say, so I am satisfied for now.
Thank you Sir for your writings and expertise shown, it is very much appreciated.
