ekallus Posted August 29, 2014 Report Share Posted August 29, 2014 I've just bought a very nice H factory PAM 253 from an m2m deal on here. I have a new ETA 7753 movement (Seconds at 9, 30 minutes at 3, 12 hours at 6) will this directly replace the A7750/7753 movement that is currently fitted? I'm presuming it must be an A7753 that's in the watch now, as it has the 30 minute sub dial at 3? One thing that puzzles me tho, is if I pull the crown out to what would be the first stop date change position, when I rotate it I can hear a mechanism clicking inside, with each turn. I thought the 7753 had a quick change date function at 10? Any help or comments would be appreciated... Link to comment Share on other sites More sharing options...
GenTLe Posted August 29, 2014 Report Share Posted August 29, 2014 I suppose that if you've date change on the crown, then it's a modified 7750, not a 7753 that, as you already noticed, has date change with a pusher at 10. So if you put a 7753 in it, then you'll not be able to change the date... Link to comment Share on other sites More sharing options...
Rolexman Posted August 30, 2014 Report Share Posted August 30, 2014 No. A7753 will fit but the date will not line up. Link to comment Share on other sites More sharing options...
ekallus Posted August 30, 2014 Author Report Share Posted August 30, 2014 Thanks. There isn't a date display on the Pam 253, so in that case, the ETA 7753 should fit? Link to comment Share on other sites More sharing options...
