BEST battery life so far!!
Rating: 5
So I initially purchased the Gen4 because the Fossil Sport was sold out and was EXTREMELY DISAPPOINTED with it. The only thing good about the Gen4 is the body; I'm in love with the black diamond stainless steel. Besides that, no. Glitchy and I had to charge it upwards of 3x a day! So when the Sport came back I immediately ordered it and decided to hold a contest of sorts to determine which one to keep. The Sport blew the Gen4 out of the water!!! *Battery really does last 24hrs *No glitching *Same features as the Gen4 including water proof I wore both watches at the same time, and what I did on one watch I did on the other. The Gen4 ended up dying on me 4 hours in (after sending texts, starting work outs, playing music on iHeart radio) the Sport lasted me all night until after I was home with continued use. No glitching and I'm sold. I sent the Gen4 back and I'm extremely happy with the Sport. I wish I got the pink onr but changing the band is super easy so whatever lol.

Beautiful & Lightweight
Rating: 5
I love this smartwatch. Before ordering, I was worried about the white nylon looking like a toy.. but after seeing it in person, I think the design is very elegant. The watch is beautiful and I love that its nice enough to wear to work and comfortable enough to wear at home. Its incredibly lightweight and feels very comfortable while exercising and throughout my day. Most of the time I forget that I have it on. I have a very small wrist size and the watch doesn't feel overly big. The software generally responds quickly, especially Google assistant. There have been a few lags here and there, but not often enough to bother me. The battery has been lasting me all day, with all-day heart rate monitoring on and tracking workouts. Good work Fossil!

I would buy this again in a heartbeat!

Reliable Wear OS Watch with good battery life.
Rating: 5
I bought this watch to use with my Google Pixel 3a XL after reading many Wear OS Watch rankings that say this is the watch for the money. After using it for a few weeks, I am pretty impressed overall. I mainly use it to help triage notifications so I don't have to continuously pull my phone out of my pocket throughout the day. The watch is easy to use, has a good battery life, and looks nice on the wrist. I have recommended picking one up to a few friends as well!

Cute & Comfy!
Rating: 4
Love the look and fit! The band is very flexible and comfortable! I am a beach photographer in Galveston (#planitinkphotographygalveston), so comfort , style and being waterproof are important to me! I ordered one for my husband and now my daughter wants one! I've always loved Fossil brand. I only wish the battery life was a little better. But, all-in-all it's a great stylish watch!

Best wear is smartwatch but more rose gold than gold
Rating: 4
This is an amazing wear is watch. My only complaint is that the silicone grey watch is more rose gold than gold and if I knew that I would have gotten black instead.

Kinda glitchy, battery life is just OK
Rating: 4
Overall, I like the watch and it fits well on my wrist. I did have to install a 3rd party app to get the notifications to work properly, and upon research, I noticed a lot of people have the same problem. Battery life is just OK... definitely need to recharge daily.

Pretty watch, bells and whistles don't work great
Rating: 3
I connected this watch to my iphone (or rather continually reconnect it throughout the day because it disconnects so often) and it works okay. It took a while for texts and calls to come through as notifications, but it randomly started working one day. Battery life is pretty good. I haven't tried to do very much on it, just use it for the time, an alarm clock, and for notifications from my phone. The watch is physically very attractive. It's a good size and the band is small enough to fit my little wrist. I like everything about it, just wish it worked better with iphones. I've read it works better with other phones.

Bad battery life
Rating: 2
The look and feel of this watch is good but has poor battery life. I workout a lot and the battery wouldn't even last for 8 hours. I have a small wrist. It couldn't detect my heart rate most of the times as the watch dint fit well around my wrist.

Loved it until it broke.
Rating: 1
I had one of the original smart watches by fossil, adored it. I wore it daily until the screen no longer worked....years. When I saw the price of the sport watch I couldn't pass it up! When I received it, it is much lighter due to being made of plastic. I wore it for a little over two weeks and really liked the function for the most part. Yesterday it slipped off my wrist and fell to concrete. The bracket that holds the band in place broke off. There is no repairing it. I'm trying to figure out if there is a warranty but this seems like something that absolutely should not happen on a watch. They should be designed for wear and tear and impact. After 2 weeks I have no watch. Horribly disappointed in the quality.
