Do it lah. As long as you are not some preowned watch Dealer trying to berlagak with pictures of shoik sendiri wearing their own stock, I am happy to see more pictures of Rolex and Omega.
I have caught quite a few preowned watch dealers who brazenly take wristshots of expensive watches and post them on the watch forums.
Kinda like a used car salesman taking pictures of himself inside luxury cars that he is selling.
A few years ago, I saw my neighbor's daughter dating a man who drives a different luxury car every time I see him in our neighborhood. So one day, during a casual conversation with my neighbor, I asked the mom about her daughter's boyfriend.
Apparently, he is a used car salesman who drives different car to see her because he wanted to impress her and also because the cars need to have their engines warmed up.
Not long after, the guy stopped coming as I guess the parents didn't approve. But the guy probably already piap piap the girl so he doesn't care.
Moral of the story : looks can be deceiving..
I wouldn't blame him if the car really needs to be warmed up but if he has the intention of "impressing" then it ain't good. Rule of thumb is to always be humble.
Same goes to watch, wearing it to wind up the movement a little (without wanting to use a watch winder) is alright, but motive to show off then sama je not good.
