This SBGA387 review aims to draw attention to the artisanal crafting in the watch and its uniqueness in design, the aspects which mark it apart from other watches, even those in its own family; while all Seiko watches are excellent, the SBGA stands apart in an aesthetic regard.

To begin, it is important to mention that the SBGA387 is an exclusive model created for the United States; featuring a push-button release in addition to a three-fold clasp, this watch demonstrates masterful execution of the art of watchmaking. Its glass coating is made of dual-curved sapphire, while the case itself is comprised of stainless steel, creating an attractive duality that emphasizes the Grand Seiko SBGA387’s artistically-driven design. Its case is sleek stainless steel, which casts a sharp contrast against the blue hues of its dial, making both steel and sapphire shine. The case is accented with a lion emblem on its back, a leonine reminder of the uniqueness of this watch line.

With a case diameter of 40mm and a thickness of 12.5, the Grand Seiko SBGA387 is a smooth and comfortable fit upon the wrist. Its case, the 44GS, is specifically created for watches of its kind, adding to the alluring uniqueness of the Grand Seiko SBGA387. The sharp angulation of the minute and hour hands cut an impressive silhouette against the underlying blue tones, and the date display located upon the face of the watch is yet another aspect of the SBGA387 that highlights its masterful creation. Even in silhouette, the aesthetic properties of the Grand Seiko SBGA387 are clearly on display. Just looking at the watch makes it clear that the design is a labor of intense care, with its specially-created case and its laborious Kirazuri-inspired face.

The texturing of the SBGA387’s dial makes its ties to Kirazuri painting clear: the sleek yet fibrous textured appearance beneath the glass evokes gold dust that has been polished to a refined point, a keystone of Kirazuri style. Even in its dial styling, the SBGA387 makes its classy and elegant origins known; this watch is a true passion piece, with every detail crafted to give service to the fine art of watchmaking.

In addition to its milestone design, the Seiko SBGA387 hosts an automatic Caliber 9R65 Spring Drive, which was created specifically for the Grand Seiko line of watches. This Spring Drive hosts an automatic reserve of 72 hours or 3 days, and it has minimal drift with only approximately 15 seconds added on to its time-tracking over the course of a month. Furthermore, the SBGA387 Grand Seiko has a function enabling the pause of the second hand altogether, which one may find convenient. There is also a tracker for the power reserve that the Spring Drive uses, creating an effective and easy reminder of how much time remains on the 72-hour countdown. The Caliber 9R65 is a marked improvement from other watch drives of its kind, with the immediate jump from the old 48-hour reserve to the new 72-hour reserve immediately noticeable. Additionally, the Caliber 9R65 powering the SBGA387 has 30 jewels within it, each jewel playing a key part in providing energy to the watch.

Boasting a screw-down crown as well as a screw case back, the SBGA387 has a quality of impenetrability that lends to its artistic image, creating a sleek and snappy appearance that is hard for outside elements to infiltrate and ruin. The SBGA387 is further equipped with 10 bar water resistance, meaning the Seiko SBGA387 can provide a flashy accessory for snorkeling or other moderate underwater diving, where the sapphire of its dial will match rather nicely with the shifting blue hues of both ocean water and pool water. Additionally, the SBGA387, which we are proud to host for sale, possesses magnetic resistance; magnetic exposure results in minimal deviation, meaning your time will be kept safely and accurately both underwater and in conditions with fluctuating magnetic draw.

Overall, with all of these features taken into account, the SBGA387 is a powerful, unique watch that possesses several aspects that hold it apart from other watches. The unique color and texturing of the face combined with the ability to take the watch underwater, coupled with its sapphire glass and its sharp hands, give the Grand Seiko SBGA387 an aesthetic capability that is truly unique. Its specially made case, backed with the visage of a lion, serves to strike home that this is a truly special watch, crafted with intense care and appreciation for the craft. The capability to pause the second hand despite its minimal drift (again, only fifteen seconds in a month’s time) further puts on display the care put into its function, as the user’s whim is considered. The SBGA387 is a powerful watch in both form and function and is a watch worth adding into any collection.
