Just ordered an Enduro 3 to replace my Epix Gen 2 Pro 51. I love the Epix but I've been regretting getting it over the Fenix for a while now. My wife has the Fenix and loves the MIP. I don't use AOD so the battery on my Epix is fine but I do get annoyed with tilt-to-wake not always working when I expect it to, and combined with the Epix not getting new features in software updates, I pulled the trigger on the 25% off deal through ExpertVoice. Very excited for the switch and will put my Epix up for sale when the Enduro arrives.
A few months ago I made the transition from the FR245 to the Epix Pro Gen 2 Sapphire and have been enjoying the change, I especially like the larger and brighter screen. I hope you have a great time with the new watch!
I am also using an AMOLED (epix pro gen 2), which replaced a fr245. I had a tough time in some scenarios with the MIPS display, such as on shaded trails and around subset (both common in my users). In these cases I am happier with the AMOLED.
I hope you enjoy it and become a running monster!!!! Have a question. Would you please turn the metronome during a running session and let me know about it? Is it audible?? I have an Enduro 2 and an Epix Pro 2 51mm and both of them are quitet to the point I have to place attention and raise the wrist to be closer to the ear... I'm considering selling both...
You can set it to vibration, sound and both. Personally, I don't like the vibration, and I'm not sure if it may drain battery in ultras
Garmin epix pro sapphire has a great screen and sapphire glass - super discounted 50% now so more a straight swap in terms of value for AWU - battery and sport no contest farming is better
Epix pro gen 2 sapphire 51mm, amoled display, less battery than the fénix but it still good and it’s cheaper since you can grab it in discount.
I was in the same boat a couple of months ago. I’m a big apple guy, love the ecosystem and the OS, nothing can beat that, but I didn’t want to charge my Apple Watch almost everyday anymore. And I also didn’t want an extension of my phone on my wrist. Wanted something different and decide to grab an epix pro gen 2, titanium sapphire for around 600 usd here in Mexico, I think it was a great deal considering it’s almost a 1000 usd watch which it’s insane tbh. I don’t regret buying it at all, I use it mainly for biking and running, 5 days a week, sleep tracking and health stats and I’m charging it once a week. The gps is great and the maps look awesome in the amoled display. As someone said above, coming from an Apple Watch, the learning curve is not easy, the menu is not as intuitive but I’m in love with the looks, roughness, functionality, battery, amoled display. Was thinking of getting maybe a fénix 7pro with MIP Disaplay to get more battery life but honestly for my activities I prefer the brightness of a amoled screen.
I’m basically full invested in the Apple ecosystem and had an AW 7 for years. I have the epix pro 2 sapphire now, and in the six months I’ve owned it I haven’t touched my Apple watch once. I did enjoy some of the connectivity for my laptop and even Apple TV, but 99% of the time I have my phone with me anyway which covers most of the stuff I used the watch for. I really don’t miss it. The epix is significantly more robust/tougher, and going from 30 hours of battery life to nearly 30 days is a game changer. Plus, the flashlight on the epix is one of the coolest features it has which sounds silly until you use the red light to save night vision when you gotta take a piss in the middle of the night.
