The first snowy day in Montreal, with about 60 cm of fresh snow overnight, covering everything in a pristine white blanket.
But my thoughts are solely on the astonishing brown dial with a turtle shell pattern on the King Seiko SPB365. This model is a limited edition of 1200 pieces, released to commemorate the 110th anniversary of Japanese watchmaking by Seiko. I was fortunate enough to get acquainted with one of these watches thanks to the Gem Bijou store in the Toronto area.
While the main focus of this review will be on the dial, it is important to note that the watch represents a much more complex product. The SPB365 is a carefully balanced creation, embodying 110 years of expertise: from the perfectly chosen proportions of the 37 mm diameter case to the unique faceted lugs, beveled bezel, and shimmering bracelet. The first impression of this watch is the classic 'Seiko-aesthetic', but in a higher price and quality segment. Let me pour another cup of coffee to take a detailed look at all the features below.
Turtle Shell Pattern Dial
In the modern watch industry, natural earthy tones and patterned dials are becoming increasingly common. If you follow new releases, you're probably familiar with popular Rolex Datejust models with themed dials, which we covered in our article about the most collectible Datejusts. Also worth mentioning are the recently discontinued Cartier Santos De Cartier WSSA0064 with a caramel-brown sunburst dial or the Rolex GMT Master II 126711CHNR with a brown half GMT bezel. The SPB365 clearly borrowed ideas from these elegant, albeit Swiss, examples.
The turtle shell pattern dial in this model is dark. So much so that distinguishing the pattern clearly requires good natural light or studio lighting. The color is deep with a slight smoky gradient: the center of the dial is light copper, almost rust-colored, smoothly transitioning to dark chocolate at the edges. From a distance, such as on another person's wrist or when placed on a shelf, the pattern is perceived as a textured gradient. Upon closer inspection in good light, unique hexagonal geometric figures resembling turtle shells become visible.
Applied baton indices stand out on the dial with their size and high-polished surface. Double markers at the 12 o'clock position are adorned with a micro-pattern - a fine and impressive detail. The Seiko logo is in bright bronze color, positioned at 12 o'clock, matching the long thin second hand. The 'King Seiko' inscription in silver matches the minute and hour hands and is located at the bottom of the dial along with the 'Automatic' label. The hands are in the classic Dauphine style - sharp and strict, characteristic of most Seiko models. The dial size is optimal for the watch case, with sufficient space between markers and details, ensuring easy time reading.
Fit on the Wrist
The watch fits perfectly on my 16.5 cm (6.5 inches) wrist. This 37 mm model has a narrow bezel and an airy yet intriguing dial. The proportions are impeccable, with a design that largely replicates the original King Seiko models from the 1960s. The massive lugs fill the space on the wrist, and the light weight and retro style give the 7-link stainless steel bracelet a special appeal.
I was surprised that in terms of build quality, this watch surpasses many 'senior' Seiko models. The feeling of weight and solidity in the hand instills confidence that the watch is built to last, which has not always been my experience with other Seiko models.
The case back is made of solid steel, creating a cool sensation when worn, unlike models with a sapphire display window. The King Seiko logo is neatly engraved on the back. Despite its compact size, the watch does not look small - the lugs and narrow bezel give it a respectable presence on the wrist.
6R31 Movement and Conclusion
It is always nice to know that a watch is entirely produced in the brand's own workshop. This is the case with the King Seiko SPB365 - it is equipped with the automatic Seiko 6R31 caliber. Although this movement is not the most accurate on the market - the stated accuracy is +25/-15 seconds per day, which aligns with my observations - it has a significant power reserve of 70 hours. The movement operates at a frequency of 6 beats per second (21,600 vibrations per hour). I also note the absence of rotor noise, which may be explained by the closed steel case back or more careful selection of the Seiko mechanism.
These watches are an excellent example of the brand's heritage. Although I have not conducted extensive research on interest in this model, I assume Seiko fans have already appreciated it. You get a well-constructed watch with a retro design, a high-quality fully in-house mechanism, and an attractive brown dial with a unique pattern. The price of $1800 is quite high for Seiko, but considering all the details, it is justified for a limited anniversary edition.
