I have a rep YM with the asian sa3135. Not the clone 2836-2 but the full size copy. I also have a 100% gen 16220 datejust with a gen 3135 movement. I was just thinking, what if I switched the movements out, would the YM have a high value, say $3000.00 and would the datejust have a value of say $1000.00 Just thinking that's all! What are your opinions. The YM has all the correct markings from correct model number and more. What do you guys think.
