Tactix 7 Series

I3 tactical for field work/deployment, Tactix for leave.

Garmin Tactix 7 user. I see absolutely no benefit over the Apple Watch besides battery life. My OLD Apple Watch was better for heart rate than this Garmin ever as been. I'm only wearing it because work gave it to me for free (and I only wear it while exercising). My wife, who swore she'd never use a smart watch now runs and sleeps wearing my ancient Apple Watch and she gets all the actually useful data that I have. Complaint about the Garmin: Several times, usually while cycling, it'll read 80-90bpm while my heart is actually 170ish. I won't even use the Garmin while cycling anymore. Sure it has extra bells and whistles that the Apple Watch might not have ...but if you can't be consistent and reliable with something as simple as HR, why waste the time/money? I'll get hate for this, but I think Garmin is more of a status symbol for "serious" endurance athletes more than it is its own unique and valuable tool.

Not a swim specific watch, but I use a Garmin Tactix 7. I find the tracking very accurate, but the watch is pretty bulky and I notice it more over long distances. Heard good things about the Garmin swim though

I spent good money on the tactix. It's great. I've beaten and abused it. It's a tank. Does all the smartphone nonsense and way way more. Lasts about 20~ days on a charge so I can actually get all the telemetry back when I sleep and it's useful.

Battery life is superb but I don’t get all WhatsApp photos/image, calendar or todos from IOS. I have a tactix 7 pro and maybe I will change to Apple Watch Ultra 3

Battery life only I am not the target user, I don’t do sport ; and have a iPhone

Garmin mip with solar display watches have superior battery life to anything else on the market. https://preview.redd.it/jmiy9113ubig1.jpeg?width=2304&format=pjpg&auto=webp&s=4e37a3943aadb450ca5061985c8fb1c2e2b94d71 I can get 200+ days on single charge when near equator.

Good lord, what are you planning on doing, ODA level stuff? An Instinct (Solar) tactical is probably all you really need, Tactix is has some serious features - like windage and range finder. Good luck!
