you can ask The Zigmeister the Asian 7750 28.800 is a great movement as long as it is oiled and serviced properly - the same is actually true for the Swiss 7750 when installed by the replica makers, since I had some that had the same issue than the Asian 7750 (slipping hands, etc.)
no the date wheel on the 7753 is different and the date cut out on the dial would have to be in a slightly different position - the same is true for Asian PAM 196s, etc
