Review: Great looking watch, well built, readable, lightweight automatic watch. - UPDATED REVIEW: I own several high end watches including Rolex, Baume & Mercer, Omega, Rado, Verchon and others. I was browsing desertcart and immediate was struck with the attractiveness of the watch. It is an automatic that is lightweight was far as automatics go, nice large but not obnoxious dial that is easily readable. No thrills watch that I like the weight, feel, construction and materials. I am glad to add this to my watch collection. It’s nice looking. Easy to read, accurate and a very attractive watch that looks and performs better than its price point. Highly recommend. Watch it works both casual and more formal attire. . Light enough so that you seldom know it’s on your wrist. Very highly recommended based on function, looks, accuracy and design. You’ll love this time piece. Bear watch I own under $600. Get one and you’ll love it. Remember that this is an automatic watch with excellent accuracy and looks. But one and wear it everywhere. Great timepiece.
