When it comes to dive watches, Seiko has a reputation that’s second to none. The brand’s commitment to precision, durability, and functionality has made it a favorite among divers and watch enthusiasts alike. In this Seiko King Turtle review, we’ll dive deep into what makes this watch the ultimate choice for underwater adventures.

The Seiko King, officially known as the Seiko Prospex SRPE03K1, is part of the Prospex line, which stands for “Professional Specifications.” It’s designed for serious divers who demand a watch that can withstand the rigors of underwater exploration. The King Turtle is a direct descendant of the iconic Seiko Turtle, which has been a fan favorite for decades.

Design and Build Quality

Design and Build Quality

One of the first things that stand out about the Seiko King is its rugged and distinctive design. The watch features a stainless steel case with a brushed finish, giving it a robust and utilitarian look. The case measures 45mm in diameter, making it substantial without being overly bulky on the wrist.

The watch’s signature “Turtle” nickname comes from the unique shape of its case, which resembles the shell of a turtle. This design not only adds character but also enhances the watch’s durability. The King Turtle is built to withstand depths of up to 200 meters (660 feet), making it suitable for recreational diving and more.

The dial of the Seiko Turtle is designed for readability in underwater conditions. The large, bold hour markers and hands are coated with Seiko’s Lumibrite luminescent material, ensuring excellent visibility in low-light environments. The date window is strategically placed at 4 o’clock, balancing the dial’s symmetry.

The watch is protected by a Hardlex crystal, which is highly resistant to scratches and impacts. Additionally, the King Turtle features a unidirectional rotating bezel with clear markings for timing dives accurately. The bezel operates smoothly and securely, a crucial feature for any dive watch.



Inside the Seiko King beats the reliable and accurate Caliber 4R36 automatic movement. This self-winding movement has 24 jewels and a power reserve of approximately 41 hours. It also features both hacking and hand-winding capabilities, allowing for precise time setting and easy manual winding if the watch hasn’t been worn for a while.

The 4R36 movement has gained a reputation for its robustness and longevity, making it an excellent choice for a dive watch. Its accuracy and durability are essential qualities for a timepiece designed for underwater use.

Bracelet and Comfort

The Seiko King comes with a stainless steel bracelet that matches the watch’s case perfectly. The bracelet features solid links and a secure fold-over clasp with a safety release. It’s comfortable to wear, even for extended periods, thanks to the well-designed links that conform to the wrist.

For those who prefer versatility, the King Turtle also includes an additional black silicone strap in the box. This strap is ideal for diving, as it’s water-resistant and provides a secure fit even when wet. The ability to switch between the stainless steel bracelet and the silicone strap adds value and adaptability to the watch.
