Portofino Chronograph Day/Date

I got my very first IWC (very first luxury watch) way back in May. I did not use it yet because it's actually a gift from my fiancé who wants me to wait until our big wedding day to use it. Anyway, I bring it out of the box last night and of course I try to set the time and day/date WITHOUT reading the instructions. And yes, I try setting the day/date during which the watch is set in that death zone of 10 to 2. I keep turning the crown but the day/date won't flip, almost like it wouldn't catch onto the gear. I'm turning and turning, still nothing. I pull the crown out to position 2 and wind it until the hour hand passes over the 24 hour mark which does flip the day and date accordingly. At this point, I still haven't read the instructions. I try again to change the day/date and still nothing. It doesn't budge. Needless to say, I read up in the instruction and I am terrified thinking I might just have broke the gears for the day date during my stupid quick change attempt. The next day (today), I call a couple of different IWC Boutiques to see what they think and they all just tell me to set it to 6:30 and try to see if I can change the day/date. I do...and it works! I then set the time to 11:55 PM and wait and watch as the watch ticks to 12:00 AM and the day and date changes! I'm very happy right now...but I will still monitor to make sure all is still well.

That was a long story. But my point in posting on this forum is...Do you guys think that IWC built into their movement a safety or preventative measure for dopes like myself who don't read the instructions and try to set the day/date during the forbidden 10-2 zone? The day/date wouldn't flip or move while I tried to quick change it so I'm wondering if that was a safety feature. Anyone with thoughts on this?

I guess you had a little angel sitting on your shoulder. Watches are not that complicated when it comes to operating them, but when you are new to them, and maybe not aware that you might break parts of them, the general guideline is like with software: RTFM! The AD might have told you, except when you didn't visit him as your fiancé collected the watch.

Your wife-to-be has been very cruel to you, giving you a watch not to be worn until THE day. There is a little warning hidden behind this. I hope the day comes soon, and that you can wear the watch with pride.

Kind regards,
Paul

Yes, very cruel. I want to wear it already! She actually doesn't mind if I start wearing it but I figure I should just hold off.

I think I did have an angel helping me out. I didn't understand why the day and date weren't flipping when I was turning the crown, and I kept on turning the crown. From what I've been reading up online, there doesn't seem to be any built in safety or prevent for damaging the day/date gears if I adjust during the forbidden hours. Like I said, I'll keep an eye on it to see if it syncs up properly. Thus far, it switches day and date right at 12:00 am (I've tried a bunch of times by setting the time to 11:58 pm and then watching as it switched to 12:00 am). Hopefully I didn't damage anything. I plan to take this baby in for maintenance regularly.
