Hi mate... I am very new to AP and by no means even close to an expert. But I am pretty sure the new version seconds@12 has an extra jewel which, at least according to the dealers, has fixed the problem. I received ny Safari about 5 days ago and it is absolutly magnificent and keeps perfect time (touch wood).
However according to many members here its not as bad as it used to be, but still would need a servicing to be trouble free. Just shoot an email to your dealer to confirm. Hope it helps
