Most do not notice or even care. My receptionist is moderately interested mainly because I usually have watches delivered to work so she knows when one is incoming and usually asks if she can see it. Funny though, even after seeing several of them, when the EXP II arrived last week, she was like "OMG is that a Rolex?, I said yes they all were/are. So even though she showed interest she really had no idea what she was looking at. Now that she knows they are Rolex's she thinks I am a super cool:). LOL, she is young.
One of the gals who works in finance asked me to get her a franken DJ so I asked Matt to build her one. She loves it and wears it every day. Another gal asked me to get a OTB rep for her husband. The rest of the staff are clueless. People who are close to me know I am a WIS and usually avoid saying anything about watches, as they know I will go into a half hour explanation of the reference and history.....they usually start to fall asleep about 2 minutes in.
In public no one notices. I might have someone say something about once a year and it is usually another WIS.
