We are excited to share our Seiko SRPC91K1 Save the Ocean Turtle watch review. This watch reissues the popular 6309 design, the first dive watch to feature a day/date display. The SRPC91K1 is a part of the SRP series, also known as the Turtle.
It has been affectionately named the “Save the Ocean” Turtle due to its partnership with the Ocean Learning Center and underwater explorer and marine conservationist Fabien Cousteau.
The watch features a cushion-shaped stainless steel case with a diameter of 44.3mm and a lug width of 22mm. It is water-resistant up to 200m and has a bi-color bezel in two shades of blue, representing the ocean’s waves.
The dial also has different tones of blue, which makes it the eye-catcher of this specific reference. The watch is powered by the Seiko 4R36 movement, which has manual winding, a stop-second function, and a 41-hour power reserve. The SRPC91K1 reinterprets the SKX series and is priced at $725 in Australia.

Seiko SRPC91K1 Save the Ocean Turtle
We are excited to introduce you to the Seiko SRPC91K1 Save the Ocean Turtle, a special edition watch from Seiko’s Save the Ocean series. This watch has a cushion-shaped stainless steel case, also known as “Turtle,” with a diameter of 44.3mm and a lug width of 22mm. The thickness measures 14 millimeters, and the lug-to-lug (length) measures 48mm. With that said, it is a relatively large case with a sporty presence on the wrist.
One of the most recognizable features of this watch is its bright-to-dark-blue color-fade dial, which is based on the blue whale.
The dial plays beautifully with the light and is complemented by a PVD-coated bezel and crown, all new elements on a well-loved automatic 44.3mm diver platform.
Under the Seiko wave beats the utilitarian but solid 4R36 caliber. It is a Seiko-built 25-jewel, 41-hour reserve movement that beats at a somewhat slower 21,600 bph.
For its purpose, the movement does its job well. The watch kept time at a very reasonable +6 seconds per day on the wrist.
The Seiko SRPC91K1 Save the Ocean Turtle is a great addition to Seiko’s Prospex line of affordable dive watches. Its shell-like case is solid and well-protected, making it reliable.
Overall, this special edition watch is a great buy for a reliable, high-performance diving watch with a unique design.
The watch is water-resistant up to 200 meters, making it suitable for recreational diving.
Seiko SRPC91K1 Turtle Review
Seiko SRPC91K1 Case
The Seiko SRPC91K1 features a cushion-shaped stainless steel case, also known as the “Turtle,” with a diameter of 44.3mm and a lug width of 22mm. The case has a thickness of 14mm and a lug-to-lug length of 48mm, offering a relatively large yet comfortable fit on the wrist.
The top of the case is satin-brushed, providing a sporty appearance, while the polished sides create an appealing contrast. The crown, positioned at 4 o’clock, is integrated into the case and is screw-down for water resistance.
With a water resistance of 200m/660 feet/20 ATM, this dive watch is suitable for various water activities. The unidirectional rotating bezel with a blue aluminum insert and luminous dot at 12 o’clock completes the distinct look of the case, making it stand out as a Turtle.
Seiko SRPC91K1 Dial
The blue “wave” dial of the SRPC91K1 transitions from a lighter blue at the top to a darker shade at the bottom, resembling the ocean’s water. The wave pattern, along with large applied hour markers and the day-date window at 3 o’clock, creates a vibrant and detailed appearance.
The hands are designed for optimal functionality, with ample Lumibrite applied for visibility in low-light conditions. The watch features a blue chapter ring and a Hardlex crystal, offering both depth and legibility crucial for divers.
Seiko SRPC91K1 Movement
Seiko equips the SRPC91K1 with the in-house caliber 4R36. This automatic mechanical movement offers a power reserve of approximately 41 hours. The movement also has hacking seconds and manual winding functions, ensuring reliable and accurate timekeeping.
Despite not having a see-through case back, the stainless steel screw-down case back provides enhanced protection and resistance against water. This makes it a robust and sturdy workhorse movement suitable for the SRPC91K1.
Seiko SRPC91K1 Strap
The SRPC91K1 has a black silicone strap featuring a stainless steel buckle and keeper, offering sporty aesthetics and practicality for water resistance.
Thanks to the drilled lugs, the watch also allows for easy strap change, allowing for a personalized style with NATO straps, metal bracelets, or leather straps.
