This was my first G-Shock, coming up on 10 years old later this year. It was a birthday present from my parents and has got a lot of use over the years.
I've had to replace the strap as the original cloth one wore out. Also only 1x battery replacement about 3 years ago.
Functions-wise its pretty basic with the stopwatch, countdown timer and alarm.
It still has alot of wrist presence in my opinion though and does still get some wrist time.
The model number on the back is dw-9000 with the 'Shock Resistant' logo.
It did take me 8 years before I bought another G but making up for it now!
