Hey Mate,
Somewhere out there on the net is a site which has all the manuals on-line,for the life of me I cant remember which but I am sure someone will chime in.
Now as said before the red hand operates on 24 hour time hence the bezel makings and you can actually track three time zones;
1) with the normal hour hand,
2) with the red hour hand and
3) with the bezel rotated to a position that relates to another time zone.
The reason the red hand is in 24 hour mode and also the two colour bezels (red/blue and black/red) is to allow the easy way to work out if it is am or pm.
Once you have played a little bit you will get the hang of it as the red hand on a 2000 model onwards is easily adjusted quickly.(Quickset).
Enjoy and if I remeber where the manual site is I will drop you a line.
