Quick TakeThe SBGW285 is more than a mere time-telling instrument; it’s a wearable piece of art reflecting nature's subtle transitions. The deep green dial whispers of Byoka, capturing that ephemeral moment when summer's warmth gives way to autumn's crisp embrace, echoing the landscape surrounding the Shizukuishi studio where it's crafted. The hand-wound Caliber 9S64, visible through the exhibition case back, beats with a steady, precise rhythm, promising a generous 72-hour power reserve. It doesn't shout; it subtly impresses. The 37.3mm case, crafted from stainless steel and paired with a dark crocodile leather band, sits with an understated elegance. The watch is a statement, a reflection of Grand Seiko's refined craftsmanship – this piece blends minimalist style with mechanical prowess, providing a connection to both the precision of Japanese watchmaking and the tranquility of nature. It is simple and classic but with an intense inspiration.

DescriptionThe Grand Seiko SBGW285, a member of the Elegance Collection, represents a refined approach to horological design, emphasizing essential functionality paired with meticulous craftsmanship. The stainless steel exterior presents a case diameter of 37.3mm, a lug-to-lug measurement of 44.3mm, and a thickness of 11.7mm. The case back is a see-through design, secured with six screws, showcasing the intricate internal mechanics. A box-shaped sapphire crystal, treated with an anti-reflective coating on its inner surface, protects the dial. The crocodile leather band is 19mm in width and accommodates a wrist perimeter of up to 195mm.

Internally, the SBGW285 houses the Caliber 9S64, a manually wound movement. This movement provides an approximate power reserve of 72 hours (3 days). Its precision is notable; the mean daily rate is specified as +5 to -3 seconds per day, as assessed during pre-assembly testing in six positions over 12 days under controlled conditions. In regular use, the accuracy is rated at +10 to -1 seconds per day. The movement’s design incorporates 24 jewels, contributing to its efficiency and longevity. From a resistance perspective, the watch provides protection against incidental water exposure, classified as splash resistant, and possesses a magnetic resistance rating of 4,800 A/m. The timepiece tips the scale at a weight of 61 grams. The dial's shade takes its visual cue from the Japanese concept of Byoka – that fleeting, subtle moment heralding autumn's approach.
