tactix Charlie

If you want to accurately track HR, get a watch that can sync with a chest strap HR monitor. I have the Garmin Tactics Charlie and the chest strapnHR Pro which is waterproof so you can swim with it. It's probably too bulky for you, but check battery life. I charge my watch once every 3-3 weeks.

I wear a tactix Charlie, about 2019 vintage, daily. It gets loads of abuse, gets strapped on the outside of my drysuit and used in water rescue, it does about 1-2 hours of GPS activity a day and battery lasts about 4-5 days doing that. Without GPS use I get about 8 days battery life.

100% worth it. I've had my Tactix Charlie for 5 years now, and the display still looks brand new. The bezel is pretty beat up, but the sapphire looks flawless

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

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.

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!

I have both, ultra 4 and tactix. Love them like children so hard to pick one but when it comes to HR accuracy and health tracking nothing comes close to Apple Watch. Get Bevel app if you haven’t yet that way you will get everything you missed about Garmin with much better accuracy
