1. I would like to ask what are the difference between Fireman series and engineer II series???
As I know, fireman has 100M water resistance, same as engineer II. It seems that fireman do not have antimagnetic, but engineer II does. But Engineer II ohio has bad night light, not beautiful, so I prefer other engineer II. But the price difference is up to 800 HK Dollars after discount. Is it worth?
What do all brothers here think?
2. May i ask what problems have you faced for ball watch? I have not tried any before. Please give me more hints.
