Just got the Fenix 5 plus, and wow the silver looks miles better.
I also have the fenix 5s with sapphire glass, and what a big differince the mineral glass is over the sapphire glass.
the mineral glass I find brighter, clear, and colours stand out a bit better
the sapphire glass is certianly darker and watch face is slightly harder to see.
the solution I will be doing is wear the fenix 5s to work, and when home and running, wear the fenix 5 plus.
The great thing is all the data can be synced between both watches, so the data I collect during the day gets synced also to my plus.
so glad I got the sliver version, makes the watch look more expensive and classier.
no need for glass protectors when I can just swap over watches.
