I have no clue who watchcollecterhk is, best you stick with our trusted dealers, I do hope you are not a spamming us.....
If you do a search on the forum you will see that the Asian ETA clone movement, that is made to "look" (not really) like the Rolex 3135 movement, is junk. It will break, or the superficial parts glued to the movement will fall off and stop your watch from working.....
Get the true Swiss ETA DSSD, or even a Swiss Sellita movement version if you can
