So tiny, so elegant
Color: Gold Harlow, Size: 16MM, Color: Gold Harlow, Size: 16MM
This ring is so elegant and beautiful. It is tiny, so if you don't have the best eyesight, this will not work for you. The band fits snugly on my size 7 ring finger. I love the shape of this ring so much. It seems like really good quality and has kept time accurately so far. Definitely worth the money, in my opinion

So fun! Bold, and cute.
Color: Gold/Black, Size: 15MM, Color: Gold/Black, Size: 15MM
I'm going to write a review right away so I can't comment on if it keeps perfect time as I just got this watch ring 90 mins ago. But first impression - AWESOME! So comfortable for me, seems very well made and it is definitely keeping time for my tiny time I've had it. I am very hopeful it is going to be sturdy and last and the battery does well. A really stylish fun way to keep track of time and have a statement piece.

Unique watch for sure
Color: Silver, Size: 15MM
So good, so cute. The face is pretty small but what do you want from a ring watch? I would say it is not for bigger fingers. I wear a size 7.5 and it fits perfectly. It does have an elastic band but when I tried it on a larger finger, it definitely pinched. I am of fan of different watches so this fits the bill. It's unique and an eye-catcher. Well done Fossil.

Pretty. Tiny. Hopefully has good battery life. UPDATE: The silver one was defective.
Color: Gold Raquel, Size: 14MM, Color: Gold Raquel, Size: 14MM
I bought both the gold and the silver ones. I have a collection of ring watches but most of them are sets you can buy for cheap. These are my first made by a well known watch company. They look big on picture but they are tiny. I bought it so when my smartwatch dies I have one on my ring to tell the time. I don't like going on my phone to check the time just to avoid distractions.
I hope the battery lasts long.
Updated review:
I started using the gold one and it works great! The silver one wasn't working so I processed a return for it. However when they shipped the replacement, there was nothing inside the tin can fossil case. I called Amazon and they refunded me for the silver one. The product works great. I probably got a defective one. My fear is maybe someone took the ring before packing it for replacement. That's just wrong. I'm going to get the silver one from Macy's instead.
