It works perfectly. I read other reviews that said it had delayed reaction and that the screen was hard to read. I have not had any issues with either. I love this watch!

Really great as a dive computer, but this isn't an every day watch. It's very inaccurate for everyday workouts.

Very good diving watch. Great information on dive and the best dive log system available! Still free too. The Apple Watch Oceanic costs $90 per year and is not as good. Little smaller screen than I would have liked (used the Mk1 before, but it stopped doing diving reports after about 5 years and Garmin wouldn't fix it. Screen is very sharp and clear though. Like improved swimming features (doesn't require a chest system for heart rate while swimming). Sleep and health features very impressive! Would highly recommend!

My Garmin Descent G1does EVERYTHING it needs to do and then some, and then some more! I was excited to see my dives automatically logged in the Garmin Dive app WITH the location of my entry and exit points. That was completely unexpected and such a pleasant surprise. I'm fairly athletic, so I love the fact that I can record every activity from strength training to cardio, skiing to hiking. You name it; it records it. Best of all, I don't need to charge my watch for 20 days.

Did my first dives earlier this week and couldn?t be happier. Comfortable on the wrist and displays the info you need. Returned from my dives and synced to the app which shows everything related to your dives. Excellent!

I wanted a dive computer and a daily wearable for health tracking, phone notifications, etc. This watch is a solid tool for all of the above. No regrets with the purchase.

I bought as a birthday gift to self. I?m a diver and needed a replacement nitrox compatible computer. The watch has more features than needed but was able to get a discount so I chose the G1.

I bought this for use as a dive computer and a everyday watch. I have the recent series watch from the fruit company and I swear I haven?t worn it since my Garmin arrived. The apps and watch features are easy to use and my logged dives are quickly transferred. This Garmin does everything my smartwatch does and MORE?..

My husband booth the descent G1 for us, replacing old oceanic neo?s. We haven?t been diving with them yet due to the backlog of repair work at our local dive shop. But I absolutely love the endless features this device provides. I use it daily for training; running, cardio, swimming, etc. I also love to view my training stats in Garmin connect. Hopefully the regs with be ready soon because I can?t wait to use it underwater. I highly recommend the descent G1!

This watch does way more than I was expecting. It?s very comfortable to wear 24/7. It?s easy to use and very intuitive. I like the blue tooth connectivity. The Garmin fitness app is incredible. It automatically populates your dives in the app and it?s easy to add your own comments. I love the graphs. The battery last longer than expected up to 21 days, and longer if your in the sun as it solar charges.
