I purchased this watch only because I own Trintec Wall clocks which have worked absolutely fine for five years. This was my second wrist watch in zulu category and unfortunately this too has not worked well. I understand this is an automatic watch but gaining more than half a minute per day speaks of poor workmanship. I spent $ 487 incl shipping plus also paid $ 164 towards import duties. After paying so much, I expected the watch to be of a very fine quality. I have been greatly disappointed. My cheapest domestic watch which costs $ 18 is so reliable and accurate. May be Trintec should consider improving their quality control or else produce this watch with Quartz movement with corresponding reduction in price. Overall not a pleasent experience.
