Congratulations on a terrific acquisition! I've found many ways to use the features although I have spent exactly no time in space.
If you have (or have access to) an I-pad, it is well worth the trouble to load the application for this watch on it. It is available on the Omega website.
There is no backlight on this watch like on the G1/G2 models. This has a negative display and when you depress the 8:00 pusher, the digits should brighten. To my 58 yr old eyes, it is sometimes harder to notice when in a bright area.

This watch looks great on all manner of straps or the bracelet. I've found some NATOs with Titanium hardware over the years.
Hope to see more of yours frequently!
