This may have been asked, the 5017 is supposed to be a ronda 1062. I went to esslinger to price one however the movement I saw did't have a date. and it's not round. I got a 9310 that was toast on the bay for dirt cheap the movement in that one is a ronda 515. which is round and has a date. I believe the 9310 is 40 and the 5017 is a 43 mm case. has any one opened a 5017 and checked out the movement model. I'm thinking of picking up another ronda 515 and put it into the 5017 I picked for dirt cheap on the bay. the movement ronda 515 goes for about 16.00. can anyone advise on the 5017 movement type.
