hmm...i like 1680 especially the red sub..but it cost around 30K++ and 50K++ for the red sub if i'm not mistaken...I almost end up getting one
if you have time (your next trip back), can call me and we can go to USJ to have a look, i'm sure a lot of the members here know where i'm referring to
better buy from those trusted seller/shop, otherwise you will not know if the part (dial, case, hands, etc) or the movement is authentic...a lot of fake now a day..even vintage
