And finally my aliexpress parts has arrived. It wasnt a brick! The watch was just what I expected but the speedmaster text is smudged out. I will soon to receive the white snoopy as well so Ill compare both. Will most likely swap out the dial as I prefer white.
Ive put them together using the v4w parts(thank you caboose). It was slightly bigger than the actual case so I sandpapered the edges to trim the diameter down by half mm ish. V4c had slight play inside the case so wasnt the right fit for my case.
One thing I wasnt sure was the rotating crown feels grindy. Not sure if its my case? stem? or Ive done something wrong. It all works though.
Interestingly the battery fitted was LR920. I assume sr626 will still fit anyways?
