guys I am looking for a mens G-shock for sweaty sport/gym/swimming session purpose, rough use style.
So I no need to bring bulky fragile smartphone. Budget <less than RM500, not into Fashion, but more into reliability/functions/practicality = best value type.
min 5years battery life, I dont want those 2-3 years one, lazy to change. tough solar is fine but not needed(prefer money spend on else where).
G-7700-1= This one good? Seems a lot of feature for low price?
G-2900F-1V = What about this? I think 7700 is beating this.
GDF-100-1A = How about this any issue?
Any other recommendation? G-shock noob here.
*despite I said I not into fashion, please dont recommend me kids/rainbow colors.

Hi Boldnut,
Here is my reply.
G-7700-1 = It's 1/1000 sec. twin stopwatch, Multi world time viewer up to 3 time zone, melody alarm which can be set on daily or weekend * powered by CR2025 battery with 5 years battery life.
G-2900F = It's an vintage old model which have Telememo (like phone books but only can store 40 records), battery life is 10 years.
GDF-100-1A = Riseman substitute that without solar powered, has ABT features (Altimeter, Barometer/Thermometer), short battery life: 2 years due to power consumption on sensors.
Alternative: G-6900-1, series 6900 with solar powered, basic alarm with 24 hour chrono and timer and worldtime. Battery life is using CTL-1616 and will be replaced from 6 to 15 years.
or GDX-6900 series, DW-6900 big brother that powered by CR-2032, up to 10 years of battery life.
cheers,
