Journey through the deep seas of time: 7 recommended Seiko diver's watches

Seiko diver's watches are highly acclaimed by divers and watch enthusiasts around the world for their durability, precision, and sophisticated design. We've carefully selected seven particularly popular models from Seiko's extensive lineup and are introducing their features and appeal.

Recommended Seiko Prospex Marinemaster Models

　The Seiko Prospex Marinemaster is Seiko's flagship diver's watch series. It is a special collection that uses a movement specifically designed for diver's watches and incorporates Seiko's technology in everything from the case to the components.

Seiko Prospex Flagship Series "Marinemaster" Ref.SBEN007

The Ref. SBEN007 is a model in Seiko's newly announced flagship Marinemaster series. Its design code is inherited from the 62MAS, a commemorative diver's watch released by Seiko in 1965. This is reflected in the case shape and large square indices. Additionally, the watch features a unique dial pattern reminiscent of the rhythm of lapping waves, and a distinctive unidirectional rotating bezel with grooves, all of which are modernized using the best of Seiko's technology.

　The Caliber 6L37 used in this watch is a new movement developed by Seiko specifically for diver's watches. This movement is not only highly shock-resistant, but also the thinnest and smallest in diameter currently available exclusively for diver's watches. Its size, along with its design, conveys the atmosphere of the "62MAS" model it is based on. This watch also features a see-through case back, allowing you to enjoy viewing the movement.

Recommended Seiko Prospex Diver Scuba Watches

　The Seiko Prospex Diver Scuba is a diver's watch that combines excellent practicality with a design that makes it easy to use in everyday life. Let's take a look at some recommended Diver Scuba models.

Seiko Prospex Diver Scuba SBEJ009 with Mechanical GMT Function

　In June 2023, Seiko announced the first Seiko Prospex diver's watch equipped with a mechanical GMT movement. One of these models is the "SBEJ009."

　The movement, Cal. 6R54, with a GMT function, has a power reserve of approximately 72 hours, and the second time zone can be easily changed by adjusting the GMT hand.

　The sleek ceramic unidirectional rotating bezel complements the solid case, enhancing the overall aesthetic of the watch. The slim bracelet fits comfortably on the wrist, ensuring a comfortable fit.

Naoki Uemura Limited Edition "Seiko Prospex Diver Scuba" SBDX057

The SBDX057 is a limited edition model that celebrates the achievements of Naomi Uemura, who has left his mark in the history of global adventure. The illustration on the dial is a silhouette of Mont Blanc as seen from Naomi Uemura's ascent route.

　The design of the SBDX057 is based on a diver's watch released in 1970. This model is also known as the one Naomi Uemura carried on his solo dog sled journey through the Arctic.

　While retaining the original's distinctive streamlined case design, the water resistance has been increased from 150m to 200m. The hands and indexes are coated with Lumibrite, ensuring high visibility even in the dark.

Popular with overseas enthusiasts: "Seiko Prospex Diver Scuba" SBDC083

　The SBDC083, which features a sturdy case, is a diver's watch nicknamed "Sumo" and is popular among watch enthusiasts overseas.

　The 45mm diameter, 12.9mm thick case bulges out towards the lugs. The index at 12 o'clock resembles a large ginkgo leaf, which is another reason for the image of a sumo wrestler.

　The movement is the Cal. 6R35, which boasts a power reserve of approximately 70 hours. Its performance as a diver's watch is also impeccable, with 200m water resistance and Lumibrite.

Seiko Prospex Marinemaster Professional Recommendations

　The Seiko Prospex Marinemaster Professional, packed with Seiko technology, is a diver's watch that has earned high praise from professional divers. We will introduce two highly reliable models that we recommend.

The shiny silver tuna can "Seiko Prospex Marinemaster Professional" SBBN049

　Seiko's 600m diver's watch features a can-like outer case for venturing to depths of 600m. Inheriting the same design code, the SBBN007 was released in 1991 as a smaller, thinner model capable of venturing to depths of 300m.

　The watch has a shape nicknamed a tuna can and is fitted with a metal bracelet, giving it the impression of being a piece of equipment, but it is also a model that is suitable for everyday use around town.

　The SBBN049 is a continuation of this line. Like the SBBN007, it uses a quartz movement and is the only current tuna-shaped diver's watch to feature a metal bracelet. This model is recommended for those who want to wear the Marinemaster Professional Tuna Can, a serious diving watch, on a daily basis.

Lightweight, large-case "Seiko Prospex Marinemaster Professional" SBDX038

The SBDX038 is a model that features black and pink gold coloring. It is a professional-grade diver's watch with 1000m water resistance.

　The case is large and gives a sense of solidity, but is made of pure titanium, making it lighter than it looks. It follows the tradition of the 1986 Quartz Divers, and the brand's iconic "tuna can" design is still intact.

　The indexes are simple in shape, ensuring excellent visibility and readability even underwater. The silicone strap is also attractive, offering high durability and comfort.

A true 300m diver: the Seiko Prospex Marinemaster Professional SBDX023

　This current model is part of the Seiko Prospex Marinemaster Professional series for professional divers, and it follows the same design code as the 300m diver released in 1968.

　This model can be said to have inherited the similarly designed "SBDX001" released in 2000 and its successor, the "SBDX017." Like the SBDX017, it uses the Caliber 8L35. However, it features a sapphire crystal for the crystal, making it stronger overall than the SBDX017. It is also worth noting that the bezel, which is prone to scratches, is made of ceramic.

　There are many current watches in the Diver Scuba series that use the design of a 300m diver. However, there are only a few current watches in the Marinemaster Professional series that use this design. This is not to be missed by anyone looking for a 300m diver that is suitable for saturation diving.

If you're looking for a diver's watch, choose Seiko.

　Of the nine series offered by Seiko Prospex, three currently include diver's watches. All are popular models boasting high functionality and excellent design.

　While there are many excellent diver's watches from other luxury watch brands, Seiko's diver's watches are also worth considering.
