Seiko SRPG17 nicknamed the "Tortoise" based on its case design and pressure rating shared with Seiko's "Turtle" dive watch. The Tortoise lacks the timing bezel of the Turtle but substitutes a compass bezel that can be used to determine direction (roughly) in some situations. Not a great instrument to avoid getting lost but an excellent timepiece that averages a loss of less than 5s a day. It's wearing a comfortable suede strap from Barton that complements the color of the hands and indices of the dial and bezel.
