I Got a New Digital Watch

I got a new watch. It's digital, it's Sony, and it has more features than I will ever need in my lifetime.
There's an alarm, of course, and stopwatch and timer features, but also a multiple time zone feature which will allow me to set the watch, in advance, for up to 10 cities. There's a calculator option, as well as a calendar.
And now I'm sitting her at my desk, it's getting late at night, and I'm trying to figure all of these features out, without using the instruction book. This is an uphill battle, to say the least.
But for the moment, it's entertaining. And it's keeping my mind off the serious issues in life. And no, I really don't want to talk about those. I know that some people use their blogs to talk about all of the "big issues" that are happening in their lives, but that't not me. I use this blog talk about fun stuff.
And right now, that means my new watch.
I just made it beep, twice, very loudly. Not much else happened, though. Trying the other button, the screen flashed the world "error" at me.
Setting the time, which I did earlier today, was easy. Setting the multiple time zones was also pretty simple. Getting the watch to cycle through the times, so I can see my local time again, after checking on DC, London, Rome, Jerusalem, New Dehli, Tokyo, Honolulu, and Los Angeles is not so easy. The watch doesn't want to stop scrolling.
I'm thinking that if I can't this working pretty soon, I'll either break down and open the instruction book, or I'll open the back of the watch and pull out the battery.
I don't really want to do that, though, because I'll lose the current settings, and invalidate the warranty for 500 meter water resistance.
Ah, decisions, decisions....
