It's big..yes, but if you're into outdoors, hiking, shooting...this watch does it all. It won't give you readings as a diver...but for navigation...it is a must. Was in a very remote area in the southern parts of the Philippines. Nothing else picked up GPS navigation. This did. Easily. The Ballistic version is not sold in the Philippines for good reason, but mine is from the US and does have it. Testing it out for ranging and shooting....1 kilometer (roughly over a thousand yards as it is 1000 meters), it is spot on. Easily calculated for targets at that distance. Would have tried for 1 mile, but we didn't have a rifle/ammo that could hit out that far. As for the solar charging...it helps to prolong operations. If you set it to minimum...it will charge. When it is on minimum it'll run for two months or longer without being charged. When you use it for navigation, tracking, etc....It will last anywhere from ten to eighteen days depending on how heavily you use all of the crazy functions this watch has. Durability is amazing. I've had this over a year now and I have yet to scratch it. I mainly use the rubber straps as you sweat a lot where I'm at. The webbed strap will collect your sweat and will not be pleasing to smell after a while. Switching them out is easy so when it is cooler I opt for the webbing. And no...the straps do not come off in operation. This watch does so much. It will likely be the last operational watch you'll ever need....unless it's under water. For erasing information...it's so easy. So...for you military guys...it will erase everything rather quickly.

I've had mine for about 3 months and only had to charge it 3 times. the solar charging works well and really helps keep the battery life up. I've used the golf app loaded on the watch itself and it works great at a few different courses. the watch bands leave a little to be desired, and the cost is high. but overall a great watch.

This will be the last watch you ever have to buy. The Tactix does everything you could possibly ask it to do and more. Built very hardy, it's kept up with my rugged lifestyle and still doesn't even have a scratch on the face. It has a sleek, cool design and feels good on the wrist. Large watchface easy to read.

My only complaint is that the solar feature is pretty negligible. I haven't seen a change in battery life when exposing to direct sunlight for hours at a time.

O yeah I said it this is the Man watch, WELL BEYOND any other out there, and I have had many from G-Shock's "MUD RESIST" too Citizens Titanium ECO DRIVE/DIVE, all pretty top notch not to mention the SUUNTO 7, eeeh okay but, not the same even close to this GARMIN Mil Spec Tatix!! Super bad azz... Works as stated on POINT it was with in 2.6 meters on trac back.. Love the Plethora of Manly features, watch faces that it has built in, not sure why you would need a third party FACE, Garmin has every one you would possibly need built in already, soooo NIce love it It is Miles even from the predecessors like the the cheaper plastic Garmins, don't get me wrong I have owned the lesser models from Garmin, the solar Tactical in forest dark green, and the pixelated version solar, both were of Wow quality, but this "Tatix", is woop azz.... Still way out priced, I may add, but at this point I am at a draw at the G price tag, it pretty much even does all the Montana 700I does, W T F really, yes on this amazing PIECE!!!!! I would say at 800 they would go like hot cakes on a cold Christmas morning.. And being in color, WOW!!!

Let me start out by saying this is a great watch. I used this as my daily watch only removing it to shower and recharge. It worked very well with my sleep tracking and recording my steps, reading altitude, mapping locations/routes taken, receiving phone notifications and the battery life is great as well. Unfortunately, after owning this watch for a little over a year now, I'm experiencing some major malfunctions. The battery started to die faster than normal (within a day) usually lasting roughly 2 weeks granted I'm not working out everyday. The screen also began to freeze up a lot. I did research and attempted to troubleshoot and reduce the demand on the watch, limiting notifications and keeping backlight at low %. I also have done both soft and hard resets on the watch. None of the above has reduced the symptoms experienced so I contacted Garmin directly and performed troubleshooting with them as well. They also informed me that of course I was out of my warranty timeframe. Unfortunately, after the troubleshooting the results were the same and a replacement option was given. I opted not to do the replacement because they were intending to send me a refurbished device. And I would've had to pay $190 +tax and send my device prior to them shipping out the replacement. This isn't an uncommon process but I have never had good experiences with refurbished devices. Again this was a great watch when it was working as designed. Sadly, it didn't last much longer than a year. I purchased and received the watch in July 2021 and it's currently October 2022. So, for me this watch didn't meet my expectations but I hope if you purchase this device you don't have this experience. This is a great device and I hope this is just a one off experience. Take care and enjoy what it has to offer
