Another inexpensive Watch, fantastic Watch, only reason I gave a four star review, is it and others I've ordered, no gasket, I installed a new gasket and a little silicone, both on the crown and gasket, now it's 90% more waterproof, it's a no brainer, I just don't know why this company can't use a cheap gasket to make this Watch more waterproof? Simple remedy, not brain science??? Sunday June 3rd, another one of theses Watches just arrived, as with the other one~one's, this one I installed a New $.07 gasket and used Silicon grease under the crown and gasket, I left it submerged in a large vase of water, for two hours, no leaks. Just a minor modification, installed gasket a little Silicon grease makes theses Watches 90+% more waterproof and at this price, it's a no brainer, buy several for back up and or gifting, any questions, please ask I'll do my best to answer!!!
