Vacheron Constantin Overseas

Hi Folks I hope this finds everyone well and enjoying this spring like weather, I have a question that I hope some may shed light to, have had my first Panerai a PAM 176 since Oct 08, absolutely love it and the "strap thing" is shear madness as I already have 4, as I digress, back to the question, the watch is not a daily wearer as I change out daily b/t my collection, just as of this week I have notice that it is gaining time and I mean serious time like 5 -7 min over a 24 hr period any suggest........

Does anybody know if there is someplace that I could send this watch to have it serviced? The watch is a Seiko Titanium Chronograph (quartz movement). The time function works fine, but the chronograph has some problems. Specifically the chronograph second hand. The hand works to keep time, but does not reset to the correct position. When it is whipping around to reset, there are little hitches in the movement, and it resets to the wrong position - and not to a consistent position. Edit: Up........
