A friend recently acquired a pre-owned Oris Williams F1 Team Day/Date 2004, he's such a happy man for such a bargain price, until I discovered that the day/date changes at 8 o'clock instead of 12. A quick fast forward of the watch not solving the problem.
Contacted the previous owner (first hand owner) and was told it is like that when he bought it new and it is one of the features of automatic watch! I own several automatics (swiss auto), some day/date changes gradually, some at a snap after 12, but none at 8 o'clock, it's such a
big bu77sh*t. Either the watch is faulty or he is , or he thinks we're idiot, or perhaps he is! Such a common sense that date changes at 12 midnight, some movement might take 1 hour, some even 2 hours, but 4 hours advance or 8 hours late (completion at around 8 o'clock) is just a nonsense.
I suspect that he set the time at the evil zone and messed up the day/date mechanism.
The day changes gradually starting at around 2:22, and date starting at around 5:43, both completed at around 7:50, and there's a click sound for every revolution completed, here's the video:

Some forum suggested that the easiest solution is to take out the hour hand and realign from 8 to 12, can be done by local watchmaker. My doubt is will that cause any problem in future? Is the real problem solved? Or it is remaining there and harming the day/date mechanism? Hope pro's here can shed some light. Thank you.
