Quick TakePicture this, a fusion of tradition and modernity, a true ode to the "Grand Seiko Style" realized. The SBGW313 isn't just a watch; it's an experience. The manual-wind movement whispers tales of a bygone era when craftsmanship was king. A dance of gears orchestrated by your own hand, connecting you to every tick, every tock. The compact 36.5mm case isn't just a size, it's a statement. It hugs the wrist with grace. The polished facets play with light, creating a spectacle. The U.S. Exclusive piece pays homage to the fleeting beauty of Japan's late spring, the pink dial is reminiscent of Sakura blossoms set against a backdrop of a snowy Mount Iwate. The limited edition timepiece captures that ephemeral moment, freezing it in time. The SBGW313 isn't just another watch on your wrist. It is a companion, a conversation starter, an embodiment of the exquisite Grand Seiko spirit and the transient beauty of nature.

DescriptionThe Grand Seiko SBGW313, part of the Heritage Collection, is meticulously engineered, drawing inspiration from the late Spring season of Mt. Iwate. This timepiece features a stainless steel exterior with a case diameter of 36.5mm and a lug-to-lug measurement of 42.7mm. The case thickness is 11.6mm, contributing to its sleek profile. The watch is equipped with a box-shaped sapphire crystal, treated with an anti-reflective coating on the inner surface, ensuring clarity and durability. The case back is a screw type, adding to the watch's robust construction. The bracelet, also made of stainless steel, has a width of 18mm and is secured by a three-fold clasp with a push-button release mechanism. This model is driven by the manually wound Caliber 9S64 movement, which is distinguished by its precision. The movement provides a power reserve of approximately 72 hours, or 3 days. In terms of accuracy, the mean daily rate is rated at +5 to -3 seconds per day. This rate is determined under controlled conditions, where the movement is measured in six different positions over 12 days. Under normal usage, the accuracy is expected to be within +10 to -1 seconds per day.

The watch maintains a magnetic resistance of 4,800 A/m, which safeguards the movement against common magnetic fields. Water resistance is rated at 10 bar, making it suitable for everyday wear but not for deep-sea diving. The SBGW313 features 24 jewels in its movement, which contribute to its smooth operation and longevity. This limited edition piece is inspired by the unique phenomenon of observing cherry blossoms in full bloom against the backdrop of a snow-capped Mt. Iwate in late April and early May, a testament to the northern location of Iwate prefecture. The design of the SBGW313 is a modern interpretation of the 44GS, which was the first model to define the Grand Seiko Style in 1967.
