I got this watch November 12th 2017. I have had this watch for 3 months. First let me start the review by saying l am a big Gshock Collector. I have 40 gshocks and 12 Protrek watches. I love ABC watches. I ride mountain bikes ,swim , hike and go to the gym. I am a active soon to be 56 years old. I love fishing boating everything with in reason. So my review about Suunto Core. I love the way the watch feels on my wrist. I have a 7 inch wrist and the watch feels great. I like the Compass which is accurate. The Barometer is good and the Altimeter works well. The watch is easy to read during the day .  What I don't like about the watch is battery instead of solar and the watch is only water resistant to 30 meters. I have had it under water in a pool for 2 hours today Swimming no problems. I would not use this in water all day.l was taking a chance today. I forget to wear one of my gshocks or Protrek watches. The watch has a depth meter to 10 feet. But I heard a lot of reviews saying the watch leaks after swimming. I now a lot of my friends in the military wear them. I really do like the watch for comport. You can wear the watch at formal occasion to. I bought the watch because Denzel Washington wore it in the Equalizer movie. That watch was made just for the movie. The seconds on this watch are very small. Now for durability. The watch in no way could stand the treatment that a Gshock or Protrek Could . This is a great watch for comfort and I like the way it looks. I recommend this watch . I do like it and wear it often. Now I am a watch Collector. This would not be my first choice. To me the best watch is the Gshock or Protrek. Time Will tell how long it last. Good luck on any watch you buy. Remember the best watch is the one your wrist. Buy it at Amazon and save money. I will update in the future on the battery life .
