I have the SARB035 and the Sumo as well and both of them flip the date at midnight precisely.
I rarely wear the SARB033 and don't think I've ever worn it in the evening past 9, hence why I've just noticed the problem after a year of ownership.
Also, the seconds and and hour hand seem to fidget when the crown is pulled all the way out and I'm adjusting the time. Again, this does not happen on my SARB035 and Sumo.
Did I just get a lemon that needs to be warrantied out or is this par for the course w/ Seiko QC?
