But I like them both. I think I prefer the 26mm that I ordered for my 372. That just sings to me for some reason. That is the sole watch/strap combo that I have been wearing in casual situations since I got the 372 back in January. I am not so sure that it's getting darker, it could be getting lighter. The 390 is just sitting in the box (why wear a 44 when you can wear a 47), so no patina on that yet.
