Great first automatic watch.  This Orient has been running for 24 hours now, and has kept up with GMT within a second or so.  To be honest it is too close for me to tell.  It is substantial on the wrist and the level of manufacture quality is outstanding. The band links appear to be solid, not stamped. The only room I can see for improvement is the very weak dial illumination. I have not really tested the water resistance, but I did fill my kitchen sink and leave this watch in for a while, and it did fine.  On the whole I am very happy with this purchase.

UPDATE:
Now that I have had this watch for four months I have changed my review to five stars.  I love this watch so much that I am considering buying another just in case anything untoward happens to this one.
