I received a Link Calibre 6 watch as a gift and it ran slow from day one. Sent it back to the reseller as there was no Tag Heuer warrantee card. The reseller sent it out for calibration and returned it to me. The watch is losing about 4 min per week. The watch looks right and has appropriate serial # ect. Any thoughts? This does not seem acceptable for a watch of this price. Is the calibration procedure for this type of watch that unreliable? Do I have a lemon or a fake?
