## Questions & Answers

**Q: What time is it?**
A: It's Time...   It's Time...  It's VADER time!!!

**Q: It says water resistant is only splash resistant. Is this really the case or can it withstand showering/rain/drowning etc**
A: Yes it can withstand drowning. Upon resurfacing it lies still for a while building a sense of peril and then dramatically gasps and coughs up water before continuing on its adventures in chronology. Way to go!

**Q: How long dose the battery on the f91 last for?**
A: Mine is dimming now! I've had it more than twenty years. As people are saying the strap is the weak point, only lasts about two years, get a leather one when it breaks.

**Q: Silly question but, how do you change pm to am?**
A: You cannot. Only the good God almighty has the power to change time, and lo, it was him what invented it in the first place so him what's makes the day go into the night.

So yes, yes it was a very silly question.
