Since Seiko introduced Japan’s first diver’s watch in 1965, Prospex timepieces have steadily become among the world’s most renowned tool watches.
The branding is a witty wordplay that comes from the combination of two words: “Professional” and “Specifications,” which, when combined, defines the very nature and purpose of Seiko Prospex watches. They’re crafted to meet the strict requirements of diving professionals, built to survive demanding conditions while staying reliable and accurate.
A letter from a diving professional explaining that beyond the 300-meter depth, watches immediately suffer all sorts of technical and mechanical failures due to the crushing pressure at those depths, and that such damage is often irreparable.
Unbeknownst to the rest of the world at that time, and maybe even to Seiko, this letter and their research for newer technologies and a better watch design that could survive the depths as a response would later add another crucial chapter to Seiko’s rich history.
Early generations of Seiko Prospex watches were also used in the 8th Japanese Antarctic Research Expedition, serving as one of many milestones in the history of the Seiko Prospex Collection and proving its reliability and capability in extreme environments.
By 2005, Seiko released the world’s first diver’s watch powered by Spring Drive Technology and capable of surviving depths of up to 600 meters.
Developments on the Seiko Prospex line continued in the years that followed, and the LX series helped Seiko win awards at events like the Grand Prix d’Horlogerie de Genève.
New identity, same reliability
While you may not be familiar with the term, you’ve almost certainly seen watches sporting the “SKX design”. Even to the uninitiated, it’s hard to miss this iconic design. It’s the diver’s watch aesthetic we now see used across Seiko’s other collections and models, such as the Seiko 5 Sports watches. This design became so popular that it’s now associated with activewear watches from other brands, which only speaks to its success.
But what people don’t know is that the SKX’s design wasn’t a new offering from Seiko when it first became popular worldwide. After all, this particular functional watch design was originally a part of the Prospex watch style, which can be traced back to the very first diver’s watch that Seiko created, which would later be known as the precursor to the Prospex line of watches. It just so happened that a different model would later popularize the design, but that’s a story for another day.
Explore the evolution of the Prospex watch style with our top picks from the Seiko Prospex Collection below and how they measure up to modern fashion standards.
Commemorating milestones: Seiko Prospex SPB299J1 1968 “Save the Ocean” Special Edition
The Prospex SPB299J1 is a modern iteration of the same iconic diver’s watch used in the Japanese Antarctic Research Expeditions, with a new take on aesthetics and technical aspects.
The textured dial features an icy blue tone reminiscent of the glaciers in the Antarctic regions and in honor of the various environmental initiatives tied to preserving these boreal wonders and the protection of the oceans amidst the threat of global warming and climate change. The dial also features a date window, while the bold indices and watch hands feature a LumiBrite coating.
Its stainless-steel case coated with Seiko’s proprietary super hard coating measures 42mm in diameter and 12.5mm in thickness. The blue unidirectional rotating bezel adds a complementary touch to its icy aesthetics, while the exhibition display case back also features special edition markings for this commemorative timepiece. Both the watch face and the see-through back use Sapphire Crystal glass with an anti-reflective coating.
The Prospex SPB299J1 also uses the reliable Caliber 6R35 Automatic Mechanical Movement, a modern upgrade from its original iteration, and offers up to 70 hours of power reserve. An equally reliable and durable three-fold stainless-steel bracelet and an impressive 200m water-resistance rating complete this tool watch for everyday wear.
Take part in making a better change for the world in style with this legendary iteration from the Seiko Prospex Collection, available at Seiko Boutique Mitsukoshi BGC.
Crossroads of the past and present: Seiko Prospex SPB381J1 1968 GMT
The Seiko Prospex SPB381J1 is another iteration of the original Prospex watch style from 1968, with a modern reinterpretation of a tool watch for everyday wear, featuring the improved Caliber 6R54 Automatic Mechanical Movement, capable of up to 72 hours of power reserve, an improved magnetic resistance of 4,800 A/m, and supporting its added GMT function.
The stainless-steel casing also features Seiko’s super hard coating and measures 42mm in diameter and 12.9mm thick, retaining the unidirectional rotating bezel function and matching its Marine Green sunray dial.
The subtle gold details that accentuate the dial, along with the small date window, effectively create a striking presence when combined with the bold watch hands and indices, both of which are also coated with LumiBrite for low-light visibility.
While this Seiko Prospex watch doesn’t have an exhibition display case back, it still uses the same reliable Sapphire Crystal glass with an anti-reflective coating on the inner surface. Although this model leans toward larger dial dimensions and a bolder build, the stainless-steel butterfly clasp bracelet with a push-button release extender provides comfortable daily wear for any occasion or setting.
And as with all modern reinterpretations of the classic timepiece from 1968, this model features a 20-bar water resistance rating to complete its functional watch design and stay true to the details.
Take this elegant and classic Prospex watch home and get one at Seiko Boutique in Ayala Malls Manila Bay.
Dreaming of an iconic duo: Seiko Prospex SJE101J1
The Seiko Prospex SJE101J1 is exactly what you think it is at first glance. Enthusiasts and collectors will recognize right away that this model shares traits and features of both the Marinemaster and 62MAS, combining designs of these two iconic Prospex watches separated by decades into a new tool watch for everyday wear.
The compact stainless-steel case measures only 39.5mm in diameter and 12.3mm thick, making it one of the smaller offerings in the modern Seiko Prospex Collection. The case also showcases an exhibition back display, and both the see-through back and front face use box-shaped Sapphire Crystal glass with an anti-reflective coating.
This Seiko Prospex model is powered by the Caliber 6L37 Automatic Mechanical Movement, with a 4,800 A/m magnetic resistance rating and capable of up to 45 hours of power reserve, and one of the reasons for making its compact design possible since it’s among Seiko’s smallest mechanical movements to date.
Its textured charcoal black dial features horizontal patterns with brushed and polished finishing that create a mesmerizing depth and detail as light shines on the box-shaped glass. The bold watch hands and indices with LumiBrite coating provide decent luminosity in low-light conditions, and it also features a small date window.
With a 20-bar water resistance rating and a durable stainless-steel butterfly-clasp bracelet, the Prospex SJE101J1 stays safe and reliable, performing accurately as intended even during real diving scenarios.
This premium iteration of two iconic Prospex watch style designs is available at Seiko Boutique in Ayala Malls Manila Bay.
