Seiko's renowned adventure and exploration lineup, the Prospex collection, has received a significant upgrade: the addition of a dual-time display function.
When you think of Seiko's Prospex collection, images of rugged dive watches likely come to mind. However, this collection is more diverse than many realize, with one standout series being the Alpinist. Originating in 1959 as a timepiece tailored for Japanese mountain climbers, the Alpinist gained modern recognition with the release of models featuring an inner compass bezel in 1995. Among these, the Red Alpinist, distinguished by its red dial marker, garnered attention in various editions, including a dual-time version—but only in a quartz-powered iteration. This year, Seiko steps up its game with the introduction of mechanical GMT movements in the new SPB377 and SPB379 models, elevating the Alpinist series to new heights.
The Rise of Seiko's GMT Obsession
Seiko's recent fixation on the dual-time, traveler's, or GMT complication is evident, and for good reason. This feature has been integrated into a range of Seiko timepieces, from the entry-level Seiko 5 Sports to the Prospex 1968 Diver—the brand's first mechanical GMT dive watch. Even unexpected releases like the Presage Style 60s and the re-edition of the Navigator have embraced this practical functionality. Now, Seiko brings this sought-after feature to its exploration and adventure watch, the Alpinist, and it's a move that makes perfect sense. But why is the GMT complication so relevant for a watch like the Alpinist? Let's delve into that.
Modernizing the Alpinist Legacy
When examining the contemporary iteration of the Seiko Alpinist, which was first introduced in the mid-1990s with its distinctive rotating compass bezel and additional crown, the addition of a dual-time function feels like a natural progression. While Seiko has previously integrated a traveler's edition within the collection—a titanium perpetual calendar powered by a quartz movement—the SPB377 and SPB379 models mark the debut of mechanical GMT Alpinist watches in regular production, excluding the limited edition SPB409.
Classic Design with Enhanced Functionality
At first glance, the new Alpinist GMT models appear classic, with subtle distinctions indicating the transition to a dual-time display. However, it would be remiss to overlook the nuances that distinguish these references beyond the addition of a 24-hour hand. Beginning with the case, the Alpinist GMT maintains the ruggedness synonymous with the collection, featuring hallmark elements like the additional crown at 4 o'clock for the inner rotating bezel. Crafted from steel and coated for durability, the case boasts a modest 39.5mm diameter and a lug-to-lug measurement of 46.4mm, striking a balance between compactness and presence ideal for a sporty tool watch. With a screw-down crown and case back, the Alpinist GMT ensures a robust water resistance of 200m.
Refined Details and Upgrades
While retaining its robust construction, the Alpinist GMT showcases refinements that enhance its overall appeal. Notable upgrades include a curved sapphire crystal with anti-reflective coating, brushed surfaces paired with polished accents, and subtle bevels inside the lugs, adding a touch of sophistication to the design. The elongated guards on the crown provide additional protection, ensuring durability during outdoor adventures. The distinguishing feature of the Alpinist GMT is the black-filled engraved 24-hour scale on the fixed brushed bezel, offering a classic yet practical solution for dual-time functionality.
Traditional Elements with Modern Enhancements
When examining the dial of the new Alpinist GMT watches, one can observe a blend of tradition and modern evolution. Retaining classic features of the Alpinist lineup, such as the luminous cathedral hands and the essential rotating 360-degree compass bezel for navigation, these models offer both familiarity and innovation. The compass bezel, although requiring a bit of explanation for navigation, provides a practical tool for determining directions based on the position of the Sun and the hour hand, facilitating outdoor exploration.
Variety in Design
The Seiko Alpinist GMT is available in two distinct variations to cater to different tastes and preferences. The SPB379 model adopts a classic and utilitarian approach, featuring a matte black dial with transferred markers and numerals in a silvery-white color. In contrast, the SPB377 model offers a slightly more modern aesthetic with a sunray-brushed blue dial and raised markers and numerals. A notable departure from other members of the Alpinist family is the positioning of the markers and numerals, with Arabic markers at 3, 6, 9, and 12, diverging from the even-numbered markers seen on non-GMT versions. However, the circular date window at 4:30, while essential for a GMT watch, could have been better integrated into the overall design.
Key Distinction: The GMT Function
The central red-tipped arrow-shaped GMT hand serves as the main point of differentiation for these models. Similar to other Seiko dual-time watches, the GMT hand on the Alpinist is adjusted independently, allowing users to track a second time zone effortlessly. While this approach may not be ideal for frequent travelers, it proves highly practical in the context of adventure and exploration. The GMT function on the Alpinist serves multiple purposes, from tracking home time during global expeditions to serving as a crucial day-night indicator in extreme conditions. Much like the significance of the GMT hand on the Rolex Explorer II, the Alpinist GMT SPB377 and SPB379 emerge as highly relevant timepieces within the collection, offering both functionality and style for outdoor enthusiasts.
Reliable Power Inside
Nestled within the case and visible through a transparent caseback is the renowned calibre 6R54, shared with models like the Prospex 1968 Diver GMT and the GMT Navigator Timer Reissue SPB411. This automatic movement operates at a frequency of 3Hz and boasts a generous power reserve of 72 hours, ensuring reliable performance over extended periods. While the claimed accuracy of -15/+25 seconds per day may seem underwhelming, Seiko watches often exceed these expectations in real-world scenarios, offering consistent and precise timekeeping.
Enhancing the Adventurous Spirit
Completing the ensemble, the SPB377 and SPB379 come equipped with color-matched leather straps featuring folding clasps. While these straps offer comfort and secure fastening, some enthusiasts may find them lacking in ruggedness compared to the adventure-inspired design of the watches. A textile NATO band or a distressed leather strap could further enhance the outdoor appeal of these timepieces, complementing their robust construction and versatile functionality. While this preference is subjective, it reflects a desire to align the straps more closely with the adventurous spirit of the Seiko Alpinist collection.
In Conclusion: Seiko Prospex Alpinist Impressions
In conclusion, the introduction of the Seiko Prospex Alpinist SPB377 and SPB379, featuring a mechanical GMT function, marks a significant milestone in the evolution of the Seiko Prospex line. Crafted with precision in stainless steel cases and adorned with captivating green dials, these timepieces embody the spirit of the Japanese yama-otoko, or "mountain men," who seek the ultimate adventure. With their 24-hour displays and robust construction, these Prospex watches cater to sports lovers and adventure seekers alike. The addition of features such as a magnifier, crystal coating, and anti-reflective coating enhances both the functionality and durability of these timepieces, ensuring they are ready for any expedition. Overall, the Seiko Prospex Alpinist SPB377 and SPB379 exemplify Seiko's commitment to innovation and their dedication to providing high-quality watches for those who live for the thrill of the outdoors, truly enhancing the adventurous spirit.
