fēnix 5S

No shit. I had no issues with any of the three. My EPIX PRO 2 was discounted so your comment explains why I got it cheap but I thought the discount was due to nearing end of life. I've used all three and track 2-3 workout events a day, steps and sleep. I never had an issue with any of them. Fenix 5S sapphire, Fenix 7S, sapphire/solar, Epix Pro 2.

I’ve had my Garmin Fenix 5s for about 7 years and the battery life is still brilliant. Great watch for running.

My first Garmin was the Forerunner 10 back when I first started running and before “smartwatches” were a thing! From there, I had the Forerunner 230, Fenix 5s (was way overkill for what I needed and it was confusing to use), Vivoactive 4s, Venu 2SQ and I currently have the Venu 3s. I upgrade every couple of years and buy them directly from Garmin’s website. They have a side by side comparison tool which is very helpful when you are trying to decide between watches.

For years I wore a Fenix 5s and then 6s in rose gold. I have an Epix Pro Gen2 now which has a nice amoled display like the current Fenix 8 series. The Epix 42mm (same size as the Fenix s series) came in soft gold which is also attractive for women. I almost got that but I wanted a little more battery life so I went with a 47mm this time around. But the 42mm would been just fine and if I had a job where I have to dress more professionally I would have gone with that one. The Epix pro gen2 is the last generation and while not cheap, is an excellent deal since it does almost everything the current Fenix series does (certainly everything your wife wants) including the current gen HR sensor and has an amoled display. The Venu watches are okay but are more lifestyle and not true sports watches. I briefly had one and it wasn’t near as durable as the Fenix/Epix. All of these had sapphire glass because I’m not the most girly girl and am tough on my watches.

Still on my Fenix 5s

You're gonna love Garmin. But I would add the Fenix to the list. It's the best quality. I've had my Fenix 5s for 8 years and it still works as it did out of the box. Tons of data and metrics over the years, still has a ton of battery life and charges quickly. Best of luck in your search

Disable GSP, Bluetooth, HR, etc or buy a watch that is specific for ultra and adventure racing. You can find an older Garmin model with ultratrac for a reasonable amount if you’re not looking to break the bank.
