I recently picked up this Seiko Mini Tuna while I was updating my “Most Durable Automatic Watches” list. I went back and noticed that the Street Series Tuna I recommended is no longer easily found, and since it is one of my go-to watches, I wanted to find the next worthy successor.
I know Seiko Tuna watches are not everyone’s favorite because of the quirky case, but man do I love them! If you have been on the fence about trying one out, the several Mini Tunas out there are a good place to start, and the second-hand market is still strong, so if you buy one and hate it, it won’t be a total loss.
The SEIKO SRPH77 Mini Tuna “Save The Ocean” is a testament to Seiko’s commitment to both horological excellence and environmental consciousness. As a part of Seiko’s “Save The Ocean” series, this watch stands out for its technical prowess and carries a message of marine conservation, making it a unique blend of purpose and design.
Design and Aesthetics: One of the first things that captures attention is the watch’s stunning visual appeal. The dial, inspired by the vastness and beauty of the ocean, showcases mesmerizing blue hues that seem to shift and change as light dances across it. This is a nod to the ever-changing nature of the seas and the mysteries they hold. The “Mini Tuna” design retains the signature protective shroud of the larger Tuna models, giving it a distinctive and quirky look that Seiko enthusiasts have come to adore.
The rubber strap included with the watch is decent. It’s not one of the super soft ones found on some higher-end Prospex watches, but it has a nice stainless tell keeper with Seiko engraved. I love these straps, and the color on this one compliments the dial. I tried to swap it out for a quick release, but I couldn’t find a good aftermarket strap that matched the dial and the stock strap.
Durability: Being a dive watch, the SRPH77 is built to withstand the rigors of underwater exploration. Its robust construction ensures water resistance, making it suitable for diving and other water-related activities. The protective shroud around the case gives the watch its iconic “Tuna” appearance and adds an extra layer of protection against shocks and impacts.
Movement: Seiko, known for its reliable movements, ensures that the SRPH77 is not just a pretty face. It’s powered by Seiko’s dependable automatic movement, the 4R35, promising accuracy and longevity. The combination of Seiko’s craftsmanship and the watch’s design makes it a potential contender for any list of durable automatic watches.
The 4R36 movement is a part of Seiko’s 4R family, which can trace its lineage back to the 7S26 movement introduced in the mid-1990s. The 7S26, with its robustness and affordability, quickly became a staple in many of Seiko’s entry-level automatic watches.
As time progressed, Seiko sought to enhance this movement’s capabilities, leading to the birth of the 4R series. The 4R36, in particular, brought with it two significant upgrades: a hacking feature (where the second-hand stops when the crown is pulled out, allowing for precise time setting) and hand-winding capability.
Everyone Needs A Seiko Tuna
The SEIKO SRPH77 Mini Tuna “Save The Ocean” is more than just a watch; it’s a statement. It speaks of Seiko’s dedication to the environment and its mastery of watchmaking. For those who appreciate the quirks of the Tuna design and have a penchant for unique timepieces with a story, the SRPH77 is bound to be a cherished addition to their collection. Given its design, durability, and the cause it represents, it’s no surprise that it deserves to be on the “Most Durable Automatic Watches” list.
