Dear sifus,
As per title, which is the best for my first watch since they about the same price?

Will use the watch only when go hanging out, or to events.

Gshock GM-B2100 ~ RM2645.00
Tissot PRX Powermatic 80 ~ RM2800.00

events? definitely the prx

between those two options, I would choose Tissot PRX..
the G-Shock one is a good watch, but PRX would be more versatile, as it suits both casual and formal events..

+1 for PRX Powermatic 80

i have the Prx 80 and GMW-B5000

I say go for the Prx 80

Not worth paying over 2k for that g-shock..

I've seen the PRX Powermatic 80 in white, it's really nice. Personally, i think that's the nicest

prx, hands down

PRX for me too, try to look for shops that offer 20% discount off retail price

Better than blue? Really looking forward to buy this. Hahaha

Personal taste only, better to check the real thing out. Blue is nice but for me, I would go for white (or according to website, it's silver). Maybe because i like the touch of rose gold at the bezel, hands and indices.

Definitely PRX... then get a RM200 g shock to bang around
