Well, you can take the refund and put an order in for a new one.
The concern here is: what if the new order will face same issue?..it happened with me twice..
Then you don't buy it. At these prices don't settle put of fear.your emotions are getting the best of you. If you where buying second hand yes, but new from the Boutique has to be new and in perfect condition.
Orange is the new black. So yes, black & orange
As far as the straps I used to wear my orange with a green strap and it worked. You can pretty much use anything from black strap to grey to....orange.
On the formal wear I would think a 43.5 ceramic bezel, antireflective glass thick as hell sub will stand out all by itself. The fact that it's black won't necessarily make it less present.
So my initial response remains the same.: if it's your only watch Black, if you have others and will wear it on rotation: orange.
