The best of both worlds
The Garmin mk3i 51 mm is my go to watch for fitness training and scuba diving. I've tested the watch for a month. Gym workouts several times a week, and multiple dives to around 85 feet. It's very durable in both. With a minor scratch on the glass. I recommend putting a screen protector on it when you first get the watch. Value for the money? Yes if you are in need of a fitness tracker and dive computer. You get the best of both worlds. 100% yes! Buy this watch if you are very active in and out of the water. You'll never use all it has to offer, but you'll have room to grow and change your outdoor life style.

Worth it
Love this watch so far. Easy to read, loads of good features, works great in the water. Instantly uploaded my dive information to my phone when I got back from my dive.

High-Performance Dive Watch with Unmatched Versatility and Safety Features
I recently took the Mk3i with me to the Philippines for diving, and it exceeded my expectations. The battery life is outstanding, and it performed flawlessly during my SCUBA dives. I paired it with the wireless air pod for my tank, which allowed me to monitor my air supply or track a less experienced diver—an excellent safety feature, even though the pods are a bit pricey. I opted for the larger model with a built-in flashlight, which I initially thought I wouldn’t use but now rely on all the time. The red light mode is especially useful for staying visible when walking on dark streets at night. With so many features packed into this watch, it’s a top-tier dive computer and more. The only small downside is that the buttons can be too easily pressed, but it's not a deal-breaker. If you can invest in it, I highly recommend it for its versatility, durability, and safety-enhancing features.

Informative
The watch is great. Has so many features I’ll probably never use. But the diving portion paired with the t2 was exactly what I was looking for.

Great for groups
Great dive computer. Pros.: GPS; Haptic; Integrated air; Transmitter with no valve; Messages with other divers; Share info with other divers (essential for my, I dive with my family). Cons.: The "sonar" used to communicate does an annoying sound. I prefer my Sheerwater Teric screen customization, maybe I just didn't find the right screen mode. The GPS doesn't automatically input the dive location.

Ottimo orologio, buona visibilità in acqua
Orologio acquistato principalmente per le immersioni, molto preciso e configurabile, ma per usarlo appieno va letto gran pparte del libretto uso e manutenzione (180 pag.) E' stato sostituito ad un sunto ocea, che però nella parte subacquea risultava più versatile, spece nella parte no deco e risalite. Ha un design molto bello, da tenere conto che il 51 mm è molto grande e si fa fatica a volte a gestirlo. Viene fornito con un cinturino più lungo per agevolare il fissaggio in muta. Batteria dura circa 10 giorni.

French Gray
I am in love with this watch. Everybody wanted me to buy black but im glad i got the french gray it can be worn classy unlike the black one. While I can appreciate a more tactical looking black one, I also want something I can wear wherever the occasion takes me. The features are amazing, bright and while I was disappointed when it came out of the box the first time, i grew to love it so much as i wore it. Very happy

Buena computadora de buceo y reloj inteligente
Buena computadora de buceo, la utilizo como compu de respaldo y me arroja los mismos tiempos de fondo que mi Teric. Le compré un protector de plástico y eso la ha protegido muchísimo de golpes en el bisel. La carátula y datos durante el buceo son muy visibles, es fácil cambiar de gas o que muestre otros datos apretando un botón. Gracias a las apps de Garmin también puedes cambiar la carátula del modo reloj y personalizar casi cada valor. Es un juguete caro, espero que el uso diario no afecte al sensor de profundidad. Después de un mes de uso y 5 buceos, lo recomiendo
