Hi this is a superb Casio G-Shock Gravitymaster Watch GW3500B-1A Analog / Digital. 

The watch is in fantastic condition, I tested the functions and it works fine. 

Please note the watch will require a replacement battery as the current battery does not hold a charge when you take it out of sunlight. The watch does function fine under sunlight.  You will require a CTL920 replacement rechargeable battery (they cost roughly £15 on ebay).

If you got this far I'm sure you researched the watch already, so I'll spare you the sales pitch and just share the most distinctive specs and some personal observations:

Distinctive Specs

— 200-meter water resistance (good for swimming but not for deep diving)

— Tough Solar (CASIO’s original solar-charging system converts not only sunlight but also light from fluorescent lamps and other sources into power)

— TRIPLE G RESIST (Shock resistant, Centrifugal force resistant, Vibration resistant)

— Tough Movement (A CASIO-original thin analog movement made possible by hybrid mounting protects against damage and enables auto home position correction that helps keep you on time all the time)

— Radio-controlled Watch; Multi band 6 (additional way for time sync. This watch receives time calibration radio signals that keep the displayed time accurate)

Personal Observations

— Wow is she meaty! Just feels really solid on your arm. She's neither bulky nor clunky, just meaty and solid!

— The functions are really good fun and seeing the dials move as you switch between them is very cool

— The whole receiving time calibration radio signals thing is the coolest thing about this watch - real James Bond stuff!

— This watch has got an indestructible/ bulletproof feel to it! Now I'm not suggesting you go hardcore or anything, but this watch does feel like it could hold its own in a hard situation! Solid build!

— Her size combined with her Wu Tang yellow on black colour scheme have made this watch a real head turner!
