  • Polar Grit review- 5 star prduct
Size: Medium-Large Color: Black
I’ve been a Polar user since the 90s. I’m also a tech nerd that loves watches. So naturally I was excited to see this new Grit X and purchased it straight away. I mostly mountain bike and swim now when working out outside, so a strong and rugged watch appeals to me ( I unfortunately do go down time to time). First impressions of this watch is that it is very aesthetically impressive. The new big metal buttons and large touch display are a welcome feature. I wear full finger gloves so its nice to be able to easily find the buttons on the go. Watch is comfortable too and noticeably lighter than another brand GPS watch I own. Here are my favorite features of this watch Optical HR sensor. It is extremely accurate. I ride my bike on a smart trainer 2-3 days a week during winter/spring, using the Zwift app. I have a Polar H9 heart rate strap paired to the Zwift app. I can pair this to the Grit X, but did not detect any delta between the HR strap and the optical. On both rides, at various intensities I never saw more than a 1-2 beat delta between the two. Very cool as I like to see my HR, but don’t like to always wear a strap while mountain biking. Hill Splitter. This is a welcome feature for anyone that likes to do hill repeats. No input needed. It senses your ascent, and automatically counts your repeats for you as well as the distance and time of ascent and decent. This worked great two days ago on hill repeat workout on my road bike. This is fun and convenient feature. Screen display and touch features. I like the new display. Very clear and just bright enough. Of course easy to light up with the top left button. I have it on the weather screen all the time. Nice to have winds and temperature right in view. Route guidance. This was something I did not use a watch for until now, but very comfortable using now with the Grit X. I live in Bend Oregon where we have a plethora of trails to explore. If you want an effective way to find a prescribed route, this watch makes it very simple. You will easily stay on your trail/road and know when to turn. Battery life. I did three loooooong workouts in 2 days, had the optical HR, GPS etc. on continuous and still had tons of juice remaining went to charge it. I love all the other features such as swim metrics, sleep stages, and nightly recharge. Just started to use FitSpark and I’ll edit this review after I use it for a few weeks, but looks like another great training tool. All in all this is another great watch from Polar. This watch can do it all and more than my other brand GPS bike computer. It is a personal coach/trainer on your wrist along with the Polar Flow app, and the durability of a G-Shock. I highly recommend this sport watch. 5 Stars. ... show more

  • Keeps me informed of my fitness progress
Size: Medium-Large Color: Black
At the beginning of the COVID lockdown I was fortunate enough to locate a good deal on a new Bowflex Max Trainer M5 on Amazon. But the chest strap HRM was crappy. I then got a Polar H10 HRM chest strap, which was awesome, and exposed me to the online Polar tracking software which is even more awesome. This then prompted me to get this Grit X watch where I could add sleep monitoring and have a more full view of my calorie exertion. For my needs was likely overkill, but wanted a fitness watch with an always on display, I was sold on the Polar ecosystem and this is just a darn good-looking watch. After 3 weeks with this watch I'm very pleased. I like the extended battery life if I were to travel for work (but I have not been), but recharging the watch daily as I read my Polar Flow app takes about 15 minutes or less. I knew before buying this that the HRM function would not be as good as a chest strap. I use the chest strap for my HIIT training when it is important to get real-time results as I approach my heart beat max. The pairing of the watch and chest strap is automatic, look for the circle around the heart rate to turn from green to blue. But I take walks with my dog and longer walks with my wife and despite my living near a country border a block from a large lake my watch has had no issues tracking distance and mapping out routes I have taken. The sleep results seem to be pretty accurate as well. I like the watch face data options and I frequently keep it on the 3 hour weather forecast, which works well. While many have added the "COVID 15" I've actually lost over 15 pounds over the past 2 months. I'm in my 50's but my goal is to get back to my high school weight, so am looking to lose another 40 pounds over the next 9 months. For me, being old and overweight were 2 things I did not want when looking at COVID morbidity statistics, but now between my fitness and diet focus (which I had never done before) I really think I have created a very positive life style change for myself. I added some Barton quick release watch bands and they have worked real well and have added further watch versatility. ... show more

  • Great running watch
Size: Medium-Large Color: Green - Silver
Negatives: Great piece of equipment, don't think $480 USD is a fair price given you can buy a high end phone for that much. Why on earth does a wearable with the word 'grit' in the name not come with an included screen protector? Also no built in maps is kinda cheapskate at this price level, common polar. Adventure and 'no maps' just doesn't make sense. Also why does it have a touch screen? Seems like a waste of money when they spent so much time and effort perfecting their button interface. Positives: Mine worked perfectly out of the box, no sensor wonkeyness, never lost GPS signal, active pacing was spot on (what pace your currently at). Looks good. Wrist band is comfortable most of the time (I have small wrists). Battery life is phenomenal, wore it for several days including 5 hours of running and still had charge to spare. Pairing with phone is very simple, the phone app is also pretty good. UI is simple and easy to use and read while running. Screen is very bright and it's auto brightness works perfectly. Love the physical button interface along with the tactile feedback, usefull for running. Touch screen works but I don't know why they included it when the buttons are so nice. ... show more
