Great all around watch/computer
on July 9, 2026

Great for diving and every day wearing! All the functions work great. Its fairly easy to figure out how to use and easy to step through menu items. My only ding would be battery life for this model. The 51mm version has much longer time between charges.

Replaced three watches for me.

I love this watch. I initially thought it would replace only my older dive watch and running watch. I planned to continue using my Apple Watch for daily wear. However, it does almost everything my Apple Watch did so I wear it every day.

What a product!

The charge keeps for days, so many features it’s almost overwhelming. I use it to track all my runs and gym sessions and then all my dives. I’m so happy with my purchase. I love my watch so much.

This is a good looking dive computer that I can I wear everyday. It offers significantly more capabilities than my other bulky dive computer. Battery life is very good.

Love my Mk3i

Bought for scuba diving but died so much more. The health monitoring and scabs computer will be used a lot. So many features was overwhelming at first but learn a new one every day, it gets easier. Started using for multiple other exercises and sleep monitoring.

Ton of options
on January 5, 2026
Posted by: JWalje
I really like all of of the options available, and learning how to use them takes time. I would really like to have the option of a smaller band than the 20 mm as it is still too big and am unable to find anything smaller that will fit my wrist.

I bought this a few weeks ago and I’m still figuring it out so far it’s amazing, except I cannot get my text messages from my phone on my watch. It will ring from my phone calls, but no text messages.

Great features but no connectivity to SSI app
on August 8, 2025
Posted by: Bayleeness
I purchased this mainly due to the smartwatch + dive computer capabilities.
Its hard to forget your dive computer when its already on your wrist!
I also love the connectivity with the InReach Mini! This produces an added safety feature for ocean dives!
As i swim and do other exercises, the other sports/workout features are an added plus.
I love the air integration with the transmitter as well!
The only thing that disappoints me is thr lack of connectivity with the SSI dive app.
Other brands have easy bluetooth uploading into the SSI app, which makes logging your dives for SSI certifications and awards a breeze. I ended up buying a cheap extra dive computer to accomplish the uploads to the SSI app. In my opinion, this is not something you should have to do after spending so much on the MK3i.
I have not yet used the underwater communication or maps yet on this watch but am excited to test out those capabilitiee on an upcoming boat dive trip!
