It is unpopular in comparison to the 010, 11 series and 55 etc..
Ppl tend to prefer bigger watches hence collector much prefer 010.. however personally I like the 5’s slim bezel profile. I find it more delicate and elegant in comparison.
I attached a photo below for your own comparison and love to hear your thoughts.
Mind you, the 10 despite being a slightly bigger watch and visually more sporty, it has lower water resistant rating. 5 has 100m and 10 only rated at 50m.
To me, I find the 010 looks more “rounded” compared to the 5.. 🤔
