Great dive computer and stylish functional smart watch
First off I bought this as a backup dive computer that I can use daily for a watch. Battery seems to use about 15-20% per day in regular watch mode but make sure it’s fully charged before diving. An hour of diving took about 20% of battery life. Easy and intuitive to use in dive mode a moderate learning curve for other apps. I have only done one dive with it I will update as it gets more use. Update did my deep and night certification dives the first two I had to rely on this computer because my backlight was not on with my primary computer. It’s a little small but everything is readable I really like the arrow indicator for assent makes keeping your assent rate under control easy, in total darkness this is essential and my dive companions continuously went up way to fast. The only problem I had was the compass and that was on me I need to practice more with it. I want backups for everything under water so all I did was switch to my old school analog compass all good.

Nice Buy
Got mine yesterday. It is a high quality refurbished item. It looks like new. I think it was never used. The box is a special Garmin box with marks "refurbished" imprinted in them. Went swimming with it today and everything worked as expected. Very satisfied. The display is not very bright but I think I like the way it is, as it is capable of using ambient light to show the information besides being able to illuminate the screen. UPDATE a month later: I did four 30 meter dives with it and the watch worked as expected.

Great dive computer and smart watch!
This was an awesome deal!!! I got this watch basically so I could use it everyday and as a dive watch. It does so much! I haven't used all the functions but I do love the ones I have used. The dive function is great and reports so much after the dive so I can enter everything into my SSI dive log. I also really like how it reports on my sleep and there are many different activities that it will report on as well. It is bright enough underwater and above water to see well and I love that the app on my phone will show more indepth information. This watch was a referb but it came with all original box and paperwork. It looked brand-new. Very happy!

Very pleasantly surprised!
This watch looks and acts absolutely brand new, no scuffs or scratches at all. Even had the longer watch band, charger, and the manuals included. My guess is it was returned by the original owner during the return period but never worn. I will say I didn’t know the m2ks was different from the m2k, but apparently this watch is smaller and has a shorter battery life (it still says 7 days full charge). I think it looks plenty fine for my wrist though. Neither models can add air integration (like the m2ki can), so still no difference there. I’m very pleased, this was a fantastic deal.

Wish the refurbished watch actually worked
Euther something happened in the refurbishment process or they really messed it up. As soon as the battery got decent enough charge the screen began to haywire. It began scrolling uncontrollably at random through all the various menus. The duration that lasts is random and it also starts up at random. In between the instances of it goin haywire, I've been able to factory reset the watch hoping it would fix it but it didn't work. Returning and getting replacement but now I have to wait over a week for that to arrive. Cosmetically it looks brand new, wish it actually would work like that too.

Inspires Active Lifestyle, looks great!
Incredible product! Made me more aware of how inactive I was and inspired me to move and get out more. Very accurate for heart rate, mileage, elevation, GPS, etc. highly recommend for active people.

Simply excellent
I'm very happy. I got this watch in 2024. I already tested it in field during dive to 20meters depth for half an hour. Shows very precise and essential data. Works on battery for 7 days, sometimes 7-10 in smartwatch mode. Very satisfied with MIP screen very energy efficient which is great for AOD. IMHO it's even better than mk3 in this aspect.
