I am not sure what the point of the 47mm F5 is. I get that the F5X has mapping features that benefit from size but if the F5S and F5 are mostly identical I can't see why anyone would want the bigger F5 over the F5S other then the battery life. Why carry something heavier around for sports?
I just sold my Fenix 3 (non HR version).
Well I decided to order the Fenix 5S Black/Black Sapphire today. I feel it will be good look. I realized my favorite personal watch an Omega Speedmaster Pro is 42 mm and most Rolex watches are 40-42 mm so its a classic men's look. I know that oversized 46 mm + watches have become trendy lately but the main reason I am parting with so much money was to have a "do everything" watch that looks fantastic in a professional setting, personal setting, and sports too. Years of Forerunners I relegated to running only duty and my various attempts at wearing Garmin and Fitbit bands the rest of the time have left me feeling less than professional sometimes.
Here is a picture of the exact watch I ordered on a man's wrist that helped me make my decision...
I admit it, I have small wrists. I've worn the 42mm (the larger size) of the Apple Watch and I think it looks like the right size for me so I am thinking the 5S will be the best choice (42 also vs 47/51 for the 5/5X) for me. For a watch I would wear most the time and likely even at night the smaller size brings advantages in weight too, any other men thinking to get the 5S? The Garmin site makes such a big deal over the 5S being their new design for women that it gives me pause but I think that many mens watches are 42mm or even smaller in the real world...
