The 5172 achieves a rare feat of intricacy and a good amount of lume at the same time. The 5320 also achieves it but most models with a lot of lume look..well.. blunt.
I love wearing an aquanaut but it doesnβt have the same intricacy.
Then you have quite a few models like the 5960 and 5961 with a tiny bit of lume but not really enough to be useful. The 5172 is truly useful at night and by day looks (as shown in your photo) spectacular!
