The transparent sapphire glass bezel and bold mirror finish on the case slope create a sophisticated and luxurious feel befitting a high-end model. Sapphire glass cannot be press-molded and is carefully formed by cutting, making the manufacturing process complicated and rare, making it a special material that is only used in high-end watches. It is also called ``sapphire crystal'' overseas for its transparency and hardness, and is highly valued for its jewel-like shine.
Horizontal pattern dial with a modern look
The dial is stamped with a horizontal horizontal pattern, creating a modern impression with three-dimensionality and depth. By using horizontal rather than vertical stripes, the result is a calm yet progressive finish. The sub-dials at the 12 o'clock and 6 o'clock positions are made of metal rings with diamond-cut scales engraved on them. The details that sparkle in the light add a sense of luxury as a visual accent. In addition, Lumibrite is used for the hands and indexes to ensure high visibility even in dark places. In addition, it is equipped with practical functions such as power reserve display and day of the week display, and the dial design is designed not only for its appearance but also for the satisfaction of using it.
Fusion of lightweight titanium and elegant design
The case and bracelet are made of titanium, which is lightweight and highly durable. It provides a comfortable fit that does not cause stress even when worn for long periods of time. The surface is coated with Seiko's proprietary "Diamond Shield", which resists scratches even with daily use and maintains its beautiful appearance for a long time. In addition, the windshield uses dual curve sapphire glass with a super clear coating, ensuring high visibility while suppressing light reflection. The five-row bracelet has a clever combination of mirror finish and hairline finish, creating a balance of sportiness and elegance. The details, even down to the side panels, shine elegantly as you move. A sophisticated piece that goes well with both business and leisure.
Special proof, glove-engraved case back
The case back is engraved with a three-dimensional globe mark symbolizing Seiko Astron. This is a special edition that speaks to the brand's worldview and pride. This three-dimensional case back is a rare detail that has been used only on a limited number of high-end models in Seiko's history, such as the 100th anniversary model. The attention to detail that goes into even the invisible parts makes owning it even more satisfying.
