Does your watch date flip over exactly at midnight?

[dchernikoff]

On New Years Eve a few days ago -- my first one where I owned a Rolex -- I was excitedly watching my GMT II as the hour of midnight approached. Expecting to see the number flip from 31 to 1 right as the clock struck midnight and everyone else was kissing their significant other. But NO! It didn't flip! in fact it didn't flip to 1 until like 10 minutes past midnight. I was SO upset -- even more upset than my wife who was mad that I was staring at my watch instead of kissing her at midnight.

So is this normal? It's a K-series GMT II that I bought from a seller on here a few months ago, and it's in perfect condition. Right after I bought it I took it in to get regulated by the local Rolex service center since it was about 15 seconds/day fast, and they said it looked fine and didn't need any work done other than the regulating.

I don't think I'm going to do anything about it, but I'm just curious if this means if it's not set up properly. Or if this kind of variation not uncommon?

Thanks for any info!
