Good work watch?

[Stark4]

Hey group,
I own a company and part of my role involves me going to sales meetings (very infrequently, maybe 3-4x a month). These sales meetings usually involve me meeting with mid level managers (branch managers, general managers, etc), occasionally a larger non-profit/church, etc.

My current collection includes a black Daytona, a Pepsi, and a Longines Flagship Heritage (the one I wear exclusively for these meetings). Lately i've been itching for a new watch and thought maybe I should just upgrade the Longines.

Couple questions:
1. No one has ever noticed any of my watches, or if they have, they haven't commented on them. Should I even worry? I'd hate to lose a sale over something as trivial as a watch. After the initial 1-2 sales meetings I dont have any futher interaction with them.

2. What is a good under the radar watch that works well for this sort of work setting but something I could also enjoy wearing day to day to add another staple into my collection.
