Went to my sport shop in town, and while driving there, got an email from them saying that the have a F5 in showroom. So, just to say a few things after having it in my hands.
- it is quicker (navigating in the menu etc), surely a faster processor
- screen more vivid, slightly better luminosity but only marginal I would say
- I have a F3, so F5 is and feels like a lady watch to me, so I would probably get the F5X
Overall I like it and looking fwd to get it (F5X) and take it outdoors :-)
