Or is this military-styled watch (whether bracelet or leather band) too casual-looking? When I say business casual, it's on the conservative side. This includes anything other than a suit... so chinos and dress shirt or sports coat and tie, and so on.
One example:

I believe it's not sold in US though. I could get that same watch in black or a slightly different style in white:


What do you guys think in terms of when this watch is appropriate?

And isn't timeless a bad thing when it comes to watches?
Back to the OP's question: with the right leather or lizard band, I would have no problem wearing that with a suit, let alone business casual.
