The highest performance ever. Evolved 5X83 caliber
This model is equipped with the "Caliber 5X83" movement, which boasts the highest performance in Astron's history. It is the first time that Astron has a dual-time chronograph function, allowing you to simultaneously display and move the time in two different time zones. In addition, a new stopwatch has been installed in units of 1/20 second. Due to the increased number of motors, the sub-dial and main dial at the 6 o'clock position are driven simultaneously, significantly reducing the switching time between local and home times (up to 5 seconds compared to the previous 5X53), and the operability has been dramatically improved. In addition, the newly adopted flat antenna allows solar charging across the entire dial, and is equipped with a 1/20 second chronograph function that consumes a large power consumption. This movement truly symbolizes the "next-generation GPS solar" with improved accuracy, speed and multifunctionality. |

Astron's first vertical chrono dial
Astron's first vertical layout with sub-dial arrangement brings dynamism and depth to the entire dial. The base and sub-dials are made up of different colours and textures, and the visual contrast stands out, creating a sporty and high-quality impression. The sub-dial at 9 o'clock is placed with a three-dimensional multi-indicator that emphasizes the day of the week, providing both visibility and design. The 6 o'clock position combines dual-time display and a chronograph hour and minute calculator, improving practicality. The hour and minute hands have a three-sided cut shape, giving the impression that they have been polished down to the smallest details. The second hand functions as a basic clock under normal conditions, and as a chronograph method for measuring seconds. The date display window is also designed with a dedicated day vehicle, and the round window shape blends in with the design. In addition, Lumibrite is used for the hour, minute and second hands and indexes. It ensures high visibility even in dark places, allowing for reliable display in any situation. |

Feeling of fit, strength and beauty. Titanium case that fills everything
The case and bracelet are made of lightweight, highly durable pure titanium. The low center of gravity design makes the arms fit well and provides a comfortable fit even when worn for long periods of time. The exterior surface is coated with Seiko's unique diamond shield coating, making it less likely to get scratched even in everyday use, and maintains a beautiful finish for a long time. The windshield uses dual curved sapphire glass with a super clear coating. It reduces reflections and ensures visibility from a variety of angles. Furthermore, the bracelet buckle is equipped with a smart adjuster mechanism that allows you to adjust the size with just one push. It flexibly responds to changes in arm circumference due to temperature and physical condition, and maintains a comfortable fit in any situation. |

It's fun to be confused. Color variations that highlight three individualities
Black (SBXC151) A black model with a fresh reverse panda color scheme. The entire dial is finished in black and the sub-dial is silver, making it an inverted panda style, which is rare for Astron to date. It gives a sharp and powerful impression. Silver (SBXC153) A classic panda color that is the classic. The base is silver, and the sub-dial is layered with black paint, creating a deep black that is almost jet black. This is a classic and highly complete piece that combines visibility and elegance. The all black (SBXC155) is made entirely of black and gray, and the red accent color is removed. The grey sub-dials represent the panda in an exquisite balance, while the matte ceramic bezel accentuates the calmness and weight. This is a connoisseur-loving piece that shines with its subtle yet reliable personality. |
