The Seiko Prospex Turtle PADI SRPE99K1 is one of Seiko's many iconic diving watches that have garnered enough enthusiasm to be warranted a nickname. The Turtle nickname is easily explained when you squint a little bit. You can see the resemblance but also that it is actually a very comfortable, logical shape for a watch. The SRPE99K1 has a substantial wrist presence with its 45mm diameter, while also having a very reasonable 47.7mm lug to lug distance. This ensures it will also fit a smaller wrist than you'd expect, especially with the clever crown placement at 4 o'clock.

Under the hood is the Seiko Cal. 4R36, which features both a day and a date indicator at 3 o'clock. 

This model is part of the 'PADI' line, that Seiko produces in collaboration with the Professional Association of Diving Instructors. The details show in the distinctive name on the bottom half of the dial.

Of course the watch is also very capable of dealing with water, due to the 200m water resistance, LumiBrite lume and the very legible design. 

Within the realm of diving watches the Turtle offers a unique proposition, while also taking the practical aspects into account. A definite race winner, despite the nickname!
