Accurate time for auto watch. Look better than i anticipated. I think this model will eventually become a collector item for japanese watchesAfter using this watch for 2 weeks, I notice that it is slow by 1 to 1.5 minutes / day! Since it has an international guarantee card issued by Seiko, i brought it to Thong Sia Co (S )Pte Ltd for calibration. Thong Sia said the guarantee card with the chop RSL Watches Dealer is not an authorised dealer therefore they have to charge for any service on this watch.I bought the watch from Creation. Does Crestion has any comment on this guarantee issue??Anyway, as a warning to all buyer of watches from Lazada or similar venues, the guarantee cards may not be honoured. Thong Sia also claimed that there were many complains on cards ... MoreAccurate time for auto watch. Look better than i anticipated.

Watch face is perfectly sized.37-38mm face is just tight.Larger 41-42 watch faces feel like a wall click on the wrist.Seiko has many variations of this watch. This is my favorite.

One of a kind color display with unique day of week placement, very comfortable read time and time again. Band stands apart with smoothness that seems to float on wrist. Keeper among the best.

These watches by Seiko are some of the best one can purchase anywhere. As an automatic watch one never has to replace batteries, simply just the normal everyday movements keep it wound. I really like these. This new one especially is so well done. brushed chrome and bright chrome done in perfect combination.
The watchband is very cheaply made. The watch is wound by motion when you are wearing it. The battery does not store enough energy to made it through the night. Therefore, you have to reset it every morning.Very disappointed in this watch.
