Just went to Swiss Watch Gallery to survey the prices.. hehe
TAG Heuer Aquaracer 300m Automatic RRP RM7000

Omega Aqua Terra 150m Quartz RRP Rm8300

Longines Master Collection 42mm Power Reserve RRP 8800

Longines Master collection 38.5mm RRP 6k+

After trying these, I personally felt that I need 41mm.. 38.5mm looked too small for my wrist..
I like strap but I think I will still buy bracelet and change to aftermarket strap..
I saw this TAG Heuer Carrera automatic 39mm in internet

Wondering how will it look on my wrist..looked nice as well
