The GA-900 has the distinction of having the longest estimated battery life (7 years) of any non-solar G-Shock with an analog display. The style is inspired by industrial and construction equipment, and the yellow accents on this GA-900-1A bring to mind the Caterpillar company. With its decagonal bezel, prominent front screws, and bumpers, it sort of resembles a mini-Mudmaster. The watch also has a front LED light button, 1/100 second stopwatch, 60-minute countdown timer, and 5 alarms.

 

PROS: Longest battery life for non-solar analog G-Shock

CONS: Busy dial, no second LED light for LCD, no auto light
