Thank you all for your thoughts and advice over the past couple of weeks. I finally took the plunge and bought my first Breguet, the 5177BA. I ultimately ended up going with the enamel face as I really like the Arabic numerals. Chose the yellow gold to diversify away from my stainless steel JLC Reserve de Marche.
In addition to the brown strap in the picture below (sorry for poor quality) I also got a shiny brown strap for dressier occasions and the dark navy strap that is a bit more casual.
Now I just have to wait patiently until the watch is shipped and arrives at my door, then will try to post some better pictures.
