Garmin - Instinct 2 Solar - Tactical Edition (45mm)

had a similar questions and needs... took i2 solar tactical edition 45mm... super close when it comes to hrv and hr metrics, maybe because of the lightweight - just 53g in 45mm case... mainly using for cycling, walking and running and other sport activities... bingo

maybe instinct series 2 or 3... with solar option if hiking multi days... lighter options like 45mm i2 solar for HR (lighter watches tend to give more precise HR results overall, especially recommended ones like i2)... good luck

I have a solar instinct 2 solar. And my mom gave it to me for Christmas

Yep, I just use the 'cardio' option and it tracks these workouts fine.

Just to add (I have the I2 solar), in summer, I don't need to charge - the top up from the sum nets out the drain with regular use. GPS uses more than can be gained though, depends on the amount of GPS you use though. I don't use a whole lot and am set to go chargerless.

If you want to save yourself some money, the non-solar version is quite a bit cheaper and does everything the same, minus solar charging. For everyday use, I get little to no benefit from solar charging of my instinct 2 solar. It’s one of those things that sounds cool, but it mostly a gimmick. It *may* be useful if you’re off the grid for weeks at a time.

[9 Best Hiking Watches (2025) with GPS Worth Investing In](https://alaskanarrows.com/best-hiking-watches-with-gps-2025/) But if I’m gonna sum up my advice after all the research I’ve done on smartwatches and owning many (got the Fenix 7 and Instinct 2)…the Garmin Instinct 2 Solar is overall the best value for money watch you can get. If you want more advanced navigation and features then the Garmin Forerunner 955 and if you’re drawn to something a bit different with strong battery and maps then check out the Coros Apex 2 Pro

The first and arguably best choice id recommend for anyone is the Garmin Instinct 2 (or the larger Instinct 2X), that’s about it, check it out and see what you think Yes it has smart notifications but you can fully turn off Bluetooth at the system level, and when you do, those notifications are completely gone just like many other models in the market, they’re not as intrusive as you think If you want something even simpler, check on the Suunto Core and if you want to go for something a bit more on the high end side, check on the Coros Vertix 2 which is a premium option but has an insane battery life, dual-band GPS and amazing performance over smart features. Funnily enough, I got both the Instinct 2 and the Coros Vertix which I alternate between but the Coros hits differ with the premium feel idk.

I have the Instinct 2, solar version. It will last through 3 good days of hiking while using the GPS, if each day is like 7-8h of hiking, and it goes some sun exposure. The only time it goes down crazy fast if when I do laps in a pool. There’s probably a reason but I don’t know why. I charge it every 14days while working out every day, and using the gps every other day.

Just buy last gen's Fenix. I bought an Epix Pro earlier this month for $549, same price as the Venu 4. There have been sales for the Fenix 7X/Pro as low as $450 this year. The Instinct 2 Solar is my daily, I forget that I'm even wearing it with the light weight and not needing to charge. It feels like a normal watch and I always know the time because of the always-on MIP screen which is more readable than a G Shock and doesn't require a gesture to wake. The Epix is for hikes due to the maps.

The smartwatch stuff can be very distracting. I just turn on DND most of the time on my Garmin or even disconnect the phone. These are sports watches and when I'm exercising I just want to focus on the moment. If I'm hiking then I have my phone on airplane mode since weak signal drains battery like crazy too. Plus there's people who hike/bike/trail run with just breadcrumb maps on their Garmin Instinct. There's people that maybe sync their Instinct with their phone once a week or never at all. If you prefer design and minimalism above bells and whistles then it can be better even.

Definitely keep the Fenix 6X. My wife is still using a 6S and happy with it, I'm using an Instinct with a 7X for hiking. Apple Watch is just way too distracting. The biggest problem isn't even the horrible battery life and having to charge every day, it's the feeling of being a complete slave to your phone.  Having a phone on your wrist just isn't good for your mental health with all the constant buzzing and notifications. It creates so much stress. Sure you can turn off most of the notifications but at that point you're just using a worse Garmin. 

I love my instinct 2 solar too, I don’t need another smart device.

It has the primitivity of a Casio and the complexity of a smartwatch. It's slow navigating and interacting, but lacking function. Casio missed the smartwatch train, but is now trying to get on it. Casio is still so popular, because its users want a forget-about-it experience - years of battery life, daily functions like alarm and stopwatch. They had never made any modern 21st century technologies (now they have an AI pet), the watch was the first thing. I hope they try again as a lot of people would enjoy a simple health oriented Casio. For now, a US Garmin Instinct 2 solar might be the watch if you want simplicity and functionality for ~200€.

I have solar, but it’s not worth it on the 2 in my opinion. I don’t get a lot of charge very often, and sometimes the charging breaks altogether until I restart the watch. It works fine for running — no issues with the GPS where I run — but Garmin Coach workouts do not sync to the watch (only Daily Suggested Workouts), and it’s not compatible with PacePro or ClimbPro. I use the Runna app with a subscription, and those workouts do make it to the watch. Overall, I would say my use case is similar to yours (I do hikes and a little backpacking as well), and I would rate it as a bit limited but “fine.” I did consider splurging on an Instinct 3 Solar or possibly Forerunner 955, but I spent the money on a Runna subscription instead and don’t regret it. Edit: Another limitation of the Instinct 2 is that it does not support wrist-based running dynamics. You have to use a separate Running Dynamics Pod or HRM Pro chest strap to get those stats on an Instinct 2.
