Prospex 200M Diver Scuba Automatic White Ref. SBDC171

Write a review

Seiko’s heritage is replete with significant watches including the 1965 62MAS (the brand's pioneer dive watch) as well as the 1968 Hi-Beat Automatic Diver 300m. With Seiko downsizing many of its dive watches over the past couple of years into more ergonomic proportions for everyday wearing, the brand has used these two historical models as vintage benchmarks to create contemporary re-editions. 

The new SBDC171 with vintage design cues that we are introducing today is no exception.  This retro-inspired model is illuminated by the design of the 1968 6105-8000 Automatic Diver but has its proportions significantly reduced for greater comfort. The SBDC171 measures 41mm in diameter, with a compact lug-to-lug measurement just below 47mm. At just 12.3mm in height, the SBDC171 belongs to the thinnest Prospex models in the market. Yet the compactness of the watch does not compromise on its specifications and quality.

The stainless steel case of the SBDC171 with a diamond shield case coating is reminiscent of the late-1960s, with its “Turtle” cushion shape, straight and sharp casebands, as well as circular brushed surfaces on top. Moreover the crown is positioned at 4 o’clock in the signature Seiko style. The remainder of the case emits a classic vibe, with a screw-down crown and a robust steel screwed caseback, assuring a solid 200-meter water-resistance. A sapphire crystal with internal anti-reflective coating protects the top of the SBDC171 that is also framed by a unidirectional rotating bezel. Showcasing an aluminum insert (black with a silver scale) entirely graduated with a 60-minute scale, this bezel also rotates on 120-clicks and prevents reverse rotation. The watch is worn on a flexible 5-link brushed steel bracelet with a folding clasp, push-buttons and diving extension.

Seiko's Caliber 6R35 automatic

Additionally, the matte white dial and dark-coated hands and markers of the SBDC171 shares a tried-and-tested design with various other watches from the Prospex range, entailing the applied markers and oversized luminous hands. That being said, Seiko has selected the retro “shovel” shaped hand with luminous and red tip for the SBDC171.

To adhere to the latest requirements of ISO standards, the date has been placed at 4:30 so all markers can be luminous and readable. Inside the compact case is the in-house caliber 6R35 movement that runs at 3Hz and that is part of the brand’s mid-range portfolio of movements. This movement is concealed behind a closed caseback and is purported to have an accuracy of -15/+25 seconds daily as well as a prolonged power reserve of 70 hours. 

Seiko's LumiBrite at its best

For those of you watch collectors out there wary of oversized watches, Seiko’s thinnest dive model would surely be a sleek winner on your wrist. To snag this vintagey and compact SPB313J1 while stocks last, grab it now at Gnomon Watches.
