i agree this new movement is nice but be careful guys!!! i got the YM SA3135 and Sub SA3135. And when i tried to install gen dial and hands on the sub, everything was perfect at first but when i reinstall the movement in the case the stem broke like nothing. so i took the watch to my watchmaker and he told me that the stem was way to small and thin for a mechanical movement this is usualy used on quartz. I compare it to a aftermarquet 3135 stem, big difference!! I told angus but he didn't know and didn't get back to me yet on this subject, he ll try to shipp me a couple on my next order. The point is i had the same problem on my YM when puting the crown back in place the time change itself if i don't find the sweet spot first.
Somes pics to explain the weak part and the ''sweet spot''
The rep stem on the left and the aftermarket on the right.
This is where the stem broke, sorry for the bad pic my camera isn't that good ... but the spacing explain the hands moving when puting the crown back in. And the aftermarket stem doesn't fit this movement i tryed!!!
