Just to share, in my earlier days, Mike, I wore an ROO sec@9 and the the folks at the event I wore it too thought it was a gen.
The sec@9 was a dead giveaway, yet nobody seemed to notice, or was too polite to comment on it. I sincerely believe it was the former.
Nobody is going to scrutinize your watch, and the only people to ask you to remove it are magicians, conmen, and replica watch enthusiasts.
You can usually identify the last category from the unformed smirk and glint of suspect in their eyes. Just avoid them if you are wearing something that would be called out upon closer inspection. Or better still, go on the offense and ask about THEIR watch and see them squirm and tell you about their recent trip to MBK Bangkok.
