## Questions & Answers

**Q: Does the g shock mudmaster come with saphire glass?**
A: I've had mine for 3½ years. I wear it every day for work doing equipment maintenance. It has a very small hairline scratch on the lens and some bumps around the bezel. The band is still in great condition considering all the bug spray and sunscreen that it comes into contact with. I definitely recommend picking up any G-Shock. Casio makes the best watches in my opinion.

**Q: This seller is on g shock website as not authorized !!!???**
A: Possibly Gray market dealer, doesn’t mean the watch is bad or fake, you can email them and ask your concerns

**Q: Does this have the sun compess in case lost  ?**
A: In response to another answer: Yes, you can adjust for magnetic declination. In compass mode, hold D until it beeps, press E twice, then use A (East) and C (West) to adjust in 1 degree units. Press A and C together to exit.

**Q: What is the band length?**
A: From buckle to end of other tip, 10 inches.
