???  just how good should a GMT keep time?? mine was just overhauled and it is running slow-looses about8-10 minutes a day. i say this is not acceptable for this movement and it is going back for some adjustments. my SW hasnt been cleaned in years and it does great. i realize a mechanical movement will never keep time like a quartz. my watch guy is really good but i think he needs to work on this one some more!!!!  JON

Zodiacs in general have always had EXCELLENT movements and if the watchmaker does a good job it can keep perfect time. While I am happy with +/- 2 min. per day as I wear so many, they can be made to be dead on. Send it back.
