PAM 253 issues

The topic is Josh's PAM 253 ( http://www.pc-80108.com/pn25301-regetta-flyback-chronograph-asia-7750-28800-p-2193.html ) with the new 28800 bph asian 7750 movement.

Before I start describing the problems, let me tell you that I love the watch in every aspect, even the strap, and that these factors are merely distracting things and by far not enough to discourage me if I had to buy the same watch again.

1. The lume is pisspoor, are there any modders who deal with this particular model?

2. The movement is gaining almost exactly 30 seconds a day; can this "new" 7750 movement be adjusted at all, and where is the damn lever?

3. When I synchronise the watch with the official greenwich time (hack function is $$$$), I take good care to stop it at exactly 00 seconds and line up the minute hand with for example the 55 minutes marker. But a few minutes later, at 00 seconds again the minute hand is, let us say, at the 10 minutes 20 seconds position. Is this a fault of the inprecise markings or the movement itself?

4. The CG lever has a lot of play and keeps falling out, it only barely remains put when I carefully turn the crown so that the lever sits on the apparently thickest part of it; this seems to be an issue of the crown being too thin, but also maybe of the lever having been brushed a bit too much at the crown end.
The lever pin also seems not aligned with the crown axis and 3 o'clock marker (viewed top-down).

I will post pictures tomorrow (I hope I get to borrow a buddy's camera).

Well, no pictures so far, but here's an approximation of the lever shape. Combined with the sligthly domed rep crown it makes it a floppy lever hell! Should the lever head be round, or is that the normal shape and something else is wrong?

I think that is the normal shape of this lever. The only fix is to release the keyless works and pull the crown out a little bit (I do not know how far you can do this though) and then engage the keyless works again.

Actually, the more I think about it I'm not sure how this will work on a 7750. On a 6497 you dis-engage the crown stem by unscrewing a screw just a little bit, on a 7750 you are pushing a button.... maybe someone can tell me,

?? how do you re-engage the keyless works on the 7750 ?? Is it simply the act of reinserting the crown stem? or is it by pushing the button again (gently) and pushing the stem in until the desired length is achieved ?
