Prospex has long been a strong suit of Seiko, a company whose name is synonymous with precision timing and chronographs.
Prospex watches are built to the highest standards possible and have always been a popular choice among watch lovers. In recent years the Prospex line has expanded to include various models to suit most tastes. One such model that recently caught our eye is the Seiko Baby Tuna.
Baby Tuna is rich in history, with roots dating back to the 1960s when divers needed affordable dive watches.
The Baby Tuna story began as an inexpensive alternative to the costlier models available at the time. It received good reviews at its release and is often likened to the famous Orange Monster because of its appearance. This review will focus on evaluating the watch and providing a few insights into its investment potential.
Seiko Baby Tuna Overview
Seiko Baby Tuna is a striking and precise timepiece. The tone of the blue and black mixed together really makes it pop, while the light grey dial serves as an anchor, grounding the color theme. And while this is a 43-mm monster, it makes you feel like you are wearing nothing because it’s not overly thick nor heavy on the wrist.
It is 200 meters water-resistant to survive your deep-sea explorations. Additionally, the automatic movement means you don’t have to continually change your battery to make sure it is always ticking.
The Baby Tuna features an adjustable uni-directional bezel and a sapphire crystal that is scratch resistant. The dial has a texturized surface with luminous hands and hour markers for optimum visibility, and an anti-reflective coating for dynamic readability. The automatic movement is visible through a display case back, and the rubber strap has an integrated deployment clasp for a seamless look that secures over your wrist.
Seiko Baby Tuna Presentation
The Seiko Tuna’s ultimate representation takes this attractive timepiece to the next level. With a stainless-steel case and band, it offers a colorful look that will pair perfectly with just about any casual outfit. Offering not only superior Lumibrite hands and markers for easy viewing in dim light, but this watch is also a timepiece you can count on thanks to its shock resistance, 200-meter water resistance, and reliable quartz movement.
Seiko Baby Tuna Movement
The Baby Tuna is an updated version of the cult classic Seiko Tuna line inspired by a Japanese naval commander’s military watch. The Seiko 6R15 movement that powers it provides a 50-hour power reserve and oscillates at a frequency of 21,600 beats per hour (six beats per second) with hacking and hand winding capabilities. Its nylon strap is comfortable, functional and features several layers of material to give it its unique striped pattern.
Seiko Baby Tuna Price
A lovely timepiece for a lifetime of memories, the Seiko Prospex Baby Tuna SRP637 makes a great gift, but its intended audience is divers and those who appreciate quality watches. Priced at around $575, this watch is an amazing value, worth the price point.

Trending: Seiko Prospex Vs Seiko Padi
Baby Tuna is a unique Seiko Dive watch that has drawn many collectors to the brand. The watches are made in Japan and feature high-quality cases and bracelets.
Seiko Baby Tuna Watches are incredibly rare and are known to have resale value above the retail price when they are in mint condition.
The Baby Tuna Watch is designed with ISO standards in mind, including 200m water resistance and externally grooved lugs to decrease surface area. Seiko’s unique L-shaped gasket, crown design, and high-climate case materials go a long way towards assuring that water doesn’t seep past the shielding gasket. The crown’s surface is drilled to permit water vapors to escape and get back into the air, which also aids waterproofing. Mostly made of stainless steel (case and bracelet), this watch will keep going for a long time.
Seiko Baby Tuna is one of the best values going when it comes to automatic dive watches. It is a great watch to own if you have an appreciation for technology, history, and, as we’ve alluded to, Seiko’s commitment to quality and customer satisfaction. An overall slew of features, excellent specifications, and dependable Japanese precision make this an incredible buy.
