My dad gave me this watch in high school and I absolutely love it. It feels really solid, keeps good time and fits my size wrist perfect. They are a discontinued model, but can be had for around $400-$600 on eBay. There is also the Seiko SARB035 that has a white face and the Seiko SARB037 with a salmon face. I think this is technically the alpinist model, but I am not sure.
