Recently, this Japanese powerhouse has launched a fantastic array of reissues for both its Presage and Prospex lines. The spotlight shines on its relaunch of the famed 60s dive watches, the Seiko Prospex 62MAS 200M Automatics. Seiko's classic design remake is fitted with upgrades and proportions that had impressed all of us aficionados. So much so that we at Gnomon went in-depth with them on its history and its execution. In 2021, the Japan Maison celebrates its 140th anniversary of watchmaking, and the all-new Seiko Prospex 62MAS 200M Automatic SBDC139 is inclusive.
Short for "Professional Specification", Prospex timepieces are built with the highest standards for professionals. Seiko presents the 2017 reissues of its coveted Ref. 6217-8001, also known as the 62MAS, launched in 1965: the limited-edition Ref. SLA017 and the Seiko Prospex Diver SBDC051 and SBDC053, and into the new generation SBDC101 and 105. These watches take after the 1965 62MAS design.

Serving as a muse for this timepiece, the classic aesthetics and proportions of the Ref. 6217-8001 is upgraded in this new limited edition 140th Anniversary edition with enhanced functionality and a unique colorway,
Delving into the heart of Seiko's JDM watches, we marvel at the new engine that this renowned company has built. 2005 marks the year in which Seiko made the 6R15 engine, derived from its 7S26 movement. Using this stellar in-house manufactured calibers to create their JDM timepieces, Seiko's 7S and 6R movements are popular among Seiko collectors.
Proven to be reliable and accurate, the 6R15 movement powered the SBDC051 and 53 ever since their launches three years ago. Always seeking to improve, Seiko unveils its latest engine, the 6R35 caliber, an upgrade from the workhorse 6R15. This movement is used to power the SBDC139, making this timepiece the first of its kind to feature Seiko's new automatic caliber. Maintaining operation at 21,600 bph (3 Hertz) with hacking and hand winding capabilities, this engine has 24 jewels and a longer power reserve of 70 hours, a whopping 20 hours more than the 7R and 6S.

Limited to 6000 pieces, this dive watch sets out to be a well-received favorite in the Seiko community. The 62MAS Anniversary has a lug to lug length of only 47.6mm, lug width of 20mm, and a height of approximately 13.2mm. A throwback to the original 62MAS, this watch fits comfortably on any wrist size. It is the most petite timepiece within the Prospex range.
The 62MAS Anniversary edition has a 40.5mm stainless-steel case and a Steel bracelet, both treated with Seiko's incredible Dia-Shield coatings that ensure scratch protection and more excellent corrosion resistance. Additionally, the brushed bezel of this watch has minimal free play in its smooth 120-click unidirectional rotations. On top lies a navy blue insert that clads the same surface hardening treatment. Seiko has the numerals engraved in a stark white tone that pairs harmoniously with the blue surrounds in a celebratory mood, accentuated with its dial and handset.
Before that, admire the mixture of satin brush and Seiko high polishing on the sides of the entire timepiece. The Zaratsu polished line on its case side adds a modern twist to this vintage diver. Its dainty case allows for a more intricate and refined finishing as well.

Satin-brushed, the screw-down case back allows for a 200m water resistance, deeming this timepiece your trusty diving partner with its sterile screw-down crown at the 3 o'clock position. Branded with the signature tsunami emblem that sets Seiko dive watches apart from others, the case of the 62MAS Anniversary edition is fixed with lug holes on its sides that allow for easy strap changes. The new 62MAS Black is upgraded with a double domed anti-reflective sapphire crystal instead of the usual Hardlex mineral crystal.
Underneath the crystal sports, a zen white dial evokes a sense of peace while representing Seiko watchmaking in the past (most of them are usually white or muted silver). The 62MAS reflects the original 62MAS design and elevates it with symmetrically applied markers. Furthermore, painted with long-lasting Lumibrite, its watch hands point time clearly in the dark. Bringing back the original 1965 handset design, this diver shows a classy second hand with gleaming gold accents. Seiko blued the second hand to top things off just to freshen things up a little while in keeping with the blue-and-white anniversary color tone here.

Compared to the traditional flat bracelet design, the metal links on its steel bracelet grace this watch with an angular structure and a more solid feel. Word has it that this bracelet is a cut above the other Prospex collection such as Sumo and Shogun.
Overall, the Seiko Prospex 62MAS 200M Automatic 140th Anniversary Ref. SBDC139 is a much-anticipated addition to the Prospex collection. It is a well fabricated Seiko diver with a slim and gently tapered profile with better specs and an upgraded movement. This is a testament to Seiko's high standard.
