This is an interesting thread. I've been in professional sales for all of my career (medical sales for 20+ years)
Part of what I love about sales is that every customer is a bit like a puzzle that needs to be solved. It's never the same way twice.
My advice to the OP would be to go with your gut on what to wear and not to wear.
Just like life - the great majority of folks won't notice or care. A few will be resentful. A few will appreciate a nice timepiece.
Personally I don't wear my DDII on sales calls but find that the AP RO is just about perfect for any work situation.
There are some doctors I know will be put off by any perceived ostentation especially since we are the most expensive maker of our particular technology.
Others are true WIS types and we have a great passion in common.
It's my good fortune that our technology is clearly best in class and I enjoy being able to emphatically demonstrate that superiority.
Taking good care of my customers for decades has earned me a nice living.
Here's an after hours pic with a couple of my coworkers. AP Navy, my RO and a PAM 372.
I work with a great team and there are quite a few WIS's in our ranks.
