Seiko Prospex SPB377 Alpinist GMT Blue
A blue GMT Seiko Alpinist - fantastic watch, I have been wanting a blue Alpinist for years! But what is better than the watch was the wonderful service that I received from Arizona Fine Time. This was my first purchase from them and it will be my first stop on any future purchases.
