19mm nylon strap?

[Tudor Guy]

Hi,

I just picked up a nice 6534 with a refinished white dial that I intend to wear in rotation with my Tudor sub. I thought it would look nice with a nylon band and sort of dress it down a little bit. When I look around, nearly all of the bands for sale are either 18 or 20mm.

First question I suppose is why does nobody wear a date or datejust with a nylon band? And secondly, if I buy an 18mm band is the one mm of gap going to be noticeable (and annoy me) or am I not going to be able to notice it?

Thanks for your help
