As we’ve seen recently with the attractive Diver GMT Arctic Ocean SPB439, there’s more to Seiko’s Prospex collection than just classic models. Black Series, PADI editions or Save the Ocean are some of the recurring sub-collections that have long been offered by the Japanese manufacturer. Today, Seiko adds a new model to its range of blackened sports watches, with the Prospex Black Series SRPK43, a new diver that shares its architecture with the King Turtle.
The recipe with Seiko’s Prospex Black Series has always been pretty straightforward; take some existing and praised models from the standard collection and apply to them a blackened theme. We’ve seen this already on multiple occasions, with the SPB253J1, SPB255J1 and SPB257J1, the SRPH97K1 and SRPH99K1 or more recently the SLA067, SPB335 and SPB337. This year, as part of the brand’s 2024 collection, it’s time for the King Turtle dive watch to get a full black attire.
While visually updated, the basics remain the same. This new Black Series SRPK43 shares its case and specifications with the King Turtle models, meaning an evolution of the all-time classic Prospex Automatic Diver 200m, a.k.a the Turtle. The move to “King” meant upgraded materials, as we’ve explained in this review. The pebble-shaped case, reminiscent of a turtle shell, measures a respectable 45mm diameter. A positive aspect is the length, which remains under control at 47.7mm. Made of stainless steel, and being part of the Black Series, this new reference opts for a black hard coating (equivalent to PVD) on all surfaces.
Like its non-black siblings, this King Turtle Black Series is equipped with a sapphire crystal with a magnifier over the day-date window, instead of a Hardlex crystal. The crown and the caseback are screwed and guarantee a comfortable 200m water-resistance. Another upgrade found on this King version of the Turtle was the bezel, which opts for a new lateral grip and is equipped with a ceramic insert to host the 60-minute diving scale. It’s here executed in glossy black to match the all-black theme of this SRPK43.
Another distinctive element of this new Black Series model is its dial. While retaining the same display and layout, the dial is here simplified and presented in matte black, without texture, for optimal legibility and lower reflections. All elements of the display are coated in light green long-lasting Lumibrite Pro, which has a vivid green glow in the dark.
Completing the full-black attire, this darkened King Turtle Black Series is worn on a steel bracelet with hard coating, closed by a three-fold clasp with secure lock, push button release and diving extension. Power comes from the automatic calibre 4R36 with 41h power reserve and 3Hz frequency.
Available as a special, non-limited edition, the Seiko Prospex King Turtle Black Series SRPK43 will be in stores as of February 2024 and priced at EUR 800. For more details, please visit seikowatches.com.
