The “Turtle” case design is among the hottest and longest-lived ideas within the historical past of Seiko, showing in numerous guises throughout the model’s lineup for many years because the launch of the unique 6309 dive watch in 1976. Like so many beloved Seiko nameplates from the “Pogue,” to the “Willard,” and the “John Participant Particular,” the “Turtle” moniker was by no means an official designation from the model, however grew up organically from the model’s strong fan neighborhood. For over 40 years, then, Seiko has at all times tacitly accepted the identify, however by no means formally allowed it to affect the long-running cushion case design. The Japanese big lastly breaks this streak in 2021 for an excellent (and thematic) trigger: elevating consciousness for the Oceanic Society environmental group to assist protect the world’s seven species of sea turtles with a trio of high-spec “King Turtle” variants. These three Seiko Prospex U.S. Particular Version fashions — the Seiko Prospex SRPH55, the Seiko Prospex SRPH57, and the Seiko Prospex SRPH59 – transcend merely aiding the turtles, although, and highlight some genuinely spectacular dial ending capabilities at a remarkably reasonably priced worth level.
The acquainted 45mm chrome steel circumstances of the Seiko Prospex U.S. Particular Version collection comply with the identical rounded cushion sample as the remainder of the “Turtle” line, together with the whole lot that entails. Make no mistake, this has an actual sense of presence on the wrist, however the rolling bowl-shaped polished undercut, quick vast lugs, and comparatively low beltline make this idiosyncratic form a manageable and immensely comfy put on on all kinds of wrists. On condition that these are “King Turtle” variants, the match and end all through is effectively above the usual for this worth vary, with “Turtle” collection ending hallmarks just like the case-top radial brushing and the knurling of the crown showing noticeably crisper and extra nuanced than the usual mannequin. This collection’ use of ceramic bezel inserts stays a excessive level, with a deep shiny floor in both black or navy blue. Like the remainder of Seiko’s Prospex divers, the road is rated for an ISO-compliant 200 meters of water resistance, thanks partly to the recessed screw-down crown at 4 o’clock. Seiko’s solely actual bespoke visible cue for these circumstances comes through the caseback, the place every of the three fashions sports activities a calmly etched depiction of a sea turtle swimming. Seiko’s alternative of execution right here is puzzling, as there’s no point out of the Oceanic Society connection anyplace, and the positioning offers the caseback a decidedly busy look. If the turtle determine had changed the usual central tsunami emblem, the caseback would seemingly really feel much more balanced total.
Dial ending has been a power for Seiko throughout practically its whole product line in recent times, and for the Prospex U.S. Particular Version fashions, the model flexes each its artistic and manufacturing muscle. All three dials use a multi-stage ending course of starting from the crosshatch base texture to the dégradé shading, vibrant base colours, overlaid turtle-shell sample, and the shiny remaining floor, and the sheer manufacturing prowess that enables Seiko to make these advanced dials at a worth level effectively under $1,000 is spectacular by itself. As for the dials themselves, every one takes the signature “King Turtle” sample in a vividly completely different chromatic path. The Prospex SRPH55 is the closest this turtle shell-inspired design will get to an precise tortoiseshell look, however that is nonetheless a separate prospect from the mottled translucent look one normally associates with merchandise like tortoiseshell glasses. Very like the Seiko Presage “Starlight” restricted editions from 2017, this dial texture tends to create a shifting mushy spotlight on the dial relying on the angle of the sunshine, which performs dynamically into the brown gradient operating from the middle to the sting. Even with out including the translucent grey shell-inspired texture on high of this sample, it’s a posh and attention-grabbing dial, and because of this multi-layered ending strategy it avoids feeling too visually literal on the wrist.
The SRPH57 and SRPH59 as an alternative take this dynamic turtle-shell sample and drape it within the colours of a sea turtle’s pure habitat. The SRPH57 presents a hotter, extra tropical theme with its cyan shades, calling to thoughts the jewel-like waters of shallow equatorial seas. The turtle-shell sample is much less pronounced right here as effectively than its brown-dial counterpart, giving this mannequin a cleaner look in most lights. For these in search of a extra conventional oceanic blue, the SRPH59 presents a balanced strategy, with the turtle-shell texture hanging a center floor in visibility between the 2 different fashions. Just like the circumstances, the dial layouts of all three Seiko Prospex U.S. Particular Version fashions comply with the fashionable “King Turtle” sample and provide a noteworthy leap in refinement over their entry-level counterparts. The utilized indices are bolder and brighter with a extra pronounced polished border, Seiko’s signature sword-and-arrow handset is given a brilliant full polish, and though the day/date show at 3 o’clock nonetheless makes use of clashing white date disks the unframed window inherits a barely extra refined character due to its easy, rounded corners.
As with lots of its stablemates, the Seiko Prospex U.S. Particular Version collection makes use of the model’s venerable in-house 4R36 automated motion. The 4R36 is a solidly constructed and dependable mainstay of lots of Seiko’s entry-level choices, however whereas a lot of those watches stretch far past their market section the motion is extra consistent with expectations. It carried out admirably all through our testing session, however its 41-hour energy reserve and 21,600 bph beat price are decidedly common within the present market.
Seiko finishes the Prospex U.S. Particular Version collection with each a stainless-steel oyster-style three-link bracelet and the model’s signature silicone “accordion” strap. The bracelet is shared with the remainder of the “Turtle” and “King Turtle” collection, and its thick development pair effectively with the daring case on the wrist. That mentioned, the shaping and ending of the hyperlinks, together with the flip-lock clasp, give off a rounded and imprecise look on shut inspection regardless of its strong really feel. The silicone straps, alternatively, give these already daring designs some added persona, and Seiko’s use of refined shade right here — muted walnut-brown for the SRPH55, deep navy blue for the SRPH59, and a refined hunter-green for the SRPH57 — enhances the dials handsomely.
Each hanging in its personal proper and pointing in direction of a daring new future for Seiko dial ending, the Seiko Prospex U.S. Particular Version collection is a vibrant and classy means for the model to totally embrace the “Turtle” nameplate in any case these years.
