It is the discontinued Gulfmaster with Quad sensors. Also, it has the multi-band radio wave time syncing as well as tough solar. It is truly one of the best master of G watches out there! **More on the model**: [https://www.g-central.com/casio-g-shock-gulfmaster-gwn-q1000-quad-sensor/](https://www.g-central.com/casio-g-shock-gulfmaster-gwn-q1000-quad-sensor/) **Condition**: It is in very good condition, didn't see a lot of wrist time and kept with care. It doesn't have any visible scratches or dents. All the functions work as expected and verified that it doesn't have the seconds hand sticking issue. The watch comes with the original straps and a generic Gshock metal box seen in the pictures (no papers). I am asking $415 + shipping (US and Canada). Payment through PayPal F&F.
