I was looking for a smaller sized 100meter water resistant watch for the gym. It wears smaller than a 40mm which is great for me. 40mm is counting the pushers but its a perfect 37mm. I love the look. It's easy to operate, thin and lightweight. It's comfortable on the wrist, you could sleep with it on.
