Well, thank you,
@Racer88 ! I bought a Seiko Prospex mechanical auto-winder, put new hands on it, different bezel, loved it for a while. The it started getting inaccurate. After what I put into it, I was not going to ship it out to be regulated every few years, so gave it away on another forum. Been using a cheap Timex Expedition quartz ever since, although I still have a Seiko Cocktail Time for dressy occasions. But for me, a watch is to tell time, not "collect" or signal wealth. Tell time. Quartz is where it's at.
So, never heard of the Casio Duro until I got in this thread. I'm actually a scuba diver, so I appreciate the water resistance (not ISO AFAIK, but for $50 what do you expect?). And it's gorgeous! Have not read this entire thread, but in case you don't know about it, here is how you tell time in a second time zone with a standard dive countdown bezel.
My wife is going to Italy with my son next week, and they are 6 hours ahead of us. The only thing about this method is you need to remember whether the second time zone is ahead of you or behind you, so it's not as foolproof as a true 24-hour GMT. But again, $50. Place the top pip (60 minutes) on how many hours ahead they are (later) of or behind (earlier) the second time zone will be. If 4 hours ahead, like GMT is for me, put the triangle at 8:00, if 4 hours behind (earlier) put the pip at 4:00.
The key to this is to divide each 5 minute elapsed time mark by 5 so
5 = 1
10 = 2
15= 3
...
25 = 5
35 = 7
45 = 9
50 = 10
and so on
Here I am on Eastern time and Italy is 6 hours ahead (later) than I am.
It's 9:25 a.m. here. The hour hand is past the 15, on the way to the 20 minute mark. So 15 / 5 = 3, it is 3:25 a.m. in Italy now. Or 20 / 5 = 4, 35 minutes before 4:00 a.m.
With very little practice this can become second nature and you'll be very fast with it. When I'm not tracking another specific time zone, my triangle pip stays on 8:00 so I can track GMT time. Hope some of you had not heard of this and learned something new today! Many of you knew this already, I'm sure.
Thanks for the watch idea! Love it with my NATO straps!
