Thanks for the follow up. In your opinion, is the watch still within normal limits or do I have a complaint with the seller? The claim was that "the watch works fine".4:00am is a little excessive. Get it looked at. The 2598 chronos were phased out about 3 years ago. Your watch may be due for a service. Also, the date wheel ratchets may have slipped out of alignment causing this late date change.
