Hiya all! Just got meself my first G-Shock and it's a GIEZ GS-1000BJ

I have a few questions for all you G-Shockers out there:

1. Is the 24 hour hand adjustable independently so as to display 2 time zones at the same time?

2. Is there somewhere I can buy additional screws which holds the case protector onto the watch case?

TIA for your responses!
