Although probably discussed before (begging indulgence here) my next LT sports the SII NH 35 movement as opposed to the Myota 9015 in my current unit. As I am very happy with the 9015 performance is there any other expectation of the NH35 performance? I know squat about watch mechanics so any lay (101) level explanation as to why one watch would have a given movement would be appreciated. Hope this does not bore the audience just trying to learn. Regards.
