Hi all, firstly thanks for the opinion. Ya, abt the purpose, there is not any purpose for me to purchase either one. Something like a lot ppl get deepsea watch 1000mtr or submariner 300 mtr doesn't mean they are diver or use it for diving purpose. Oh ya, differ watch, I know, you will say one is gmt, one is chrono, one is auto, one is manual...then, yet still a mechanical watch. Just like I said earlier, you get deepsea, is that u really use it for diving up to 1000 mtr? If you buy gmt, is that mean you cannot wear it when you are in local? Ya, some may think due to the watches asked in differ cat..gmt, chrono..cannot make this kind of comparison. Sorry, I didnt ask my query clear...better I make it clearer, actually both I like, but currently, financially only allow me to get one of it. So, I need to know which one is more worth wise to buy first in case in future I don't hv any extra money to buy the other one. Appreciate more opinions given best with the reason of choice made. Thanks.
