Hahaha, because I want to and solely because nothing points me to the contrary except for few people like you who read beyond the dotted lines. Let people take it how they want. My friend, do yourself a favour by asking why people show off their watches here. Is it relevant to style forum or can we not at best stick to suit, shirt, tie and shoes?! I would also like to see if there is a specific clause of this forum that abhors the publication of phones? If that is the case, that could go as well for certain irrelevant accessories displayed on here.
Trust me, I can go on and on but I would rather focus my energy and add value to things that matter. Next?
