Seiko Prospex Turtle SRPE39K1 ‘Save The Ocean’

The Seiko Prospex Turtle ‘Save The Ocean’ SRPE39K1, or also called the ‘Manta Ray King Turtle’, 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 SRPE39K1 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.

This latest iteration has several very nice upgrades, such as a sapphire crystal protecting the stunning dial and a ceramic bezel. Under the hood is the Seiko Cal. 4R36, which features both a day and a date indicator at 3 o’clock, enhanced with a date loupe.

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.
