Caliber 5X83 Dual-Time Chronograph
Three Key Improvements
01
A 1/20-second
chronograph function
The new watch features a sub-dial at 12 o'clock that measures elapsed time in increments of 1/20th of a second.
02
A faster time
transfer function
The time of day displayed on the main dial can be switched with the one on the six o'clock sub-dial by holding down two buttons for three seconds. The main dial and sub-dial hands move simultaneously, making the time required for the transfer significantly shorter with the new Caliber 5X83 than with Caliber 5X53.
03
Further improvement
of the dial texture
The new movement's enhanced energy-charging efficiency allows the main dial and sub-dials to have contrasting colors and textures.
Dial / Bezel
Thanks to the new movement design, this is the first Seiko Astron to have a sub-dial at the 12 o'clock position and allows the main dial and sub-dials to have contrasting colors and textures, creating a more dynamic and sporty presence.
The watches feature a two-part bezel that includes an upper part in ceramic and a titanium frame. The bezel is marked with the word "CHRONOGRAPH" along with Arabic numerals.
Lumibrite
The hour, minute, and seconds hands, in addition to the three-dimensional indexes, are all filled with Lumibrite, enhancing legibility in low-light conditions.
Case /
Bracelet
Thanks to the low center of gravity of the titanium case and the dual-curved sapphire crystal glass with super-clear coating, the watches ensure high levels of comfort and legibility.
The buckle adjustment system allows the bracelet to be easily adjusted with a single push when the size fluctuates due to changes in temperature.

A new adjustment system for the buckle
A new buckle adjustment system allows you to make, at the touch of a button, the minor adjustments to the length of the bracelet that are so important when temperature or other changes make the wrist expand or contract.

Dial / Bezel
Designed of a vivid nighttime scene in which the earth is viewed from an orbiting satellite
The all-black case and bracelet, sunray-patterned dial, and yellow-gold-colored accents evoke a view of the earth at night as seen from an orbiting satellite, an image that perfectly channels the groundbreaking technology behind Astron GPS Solar.
The two-part bezel consists of a multi-faceted ceramic upper portion and a yellow-gold-colored titanium frame to create a brilliance that further evokes this shimmering night view.
Bracelet / Crown
Special bracelet and crown made of ceramic
The bracelet's center links and the tip of the crown are created with ceramic that has a glossy surface, while the outer links are made of titanium with a black super-hard coating.
Case Back
A case back that tells the story of Seiko's founder.
The yellow-gold-colored case back carries company founder Kintaro Hattori's name and the trademark "S" that he registered in 1900 as a symbol of the Seikosha factory. Just above the trademark appears the phrase that so aptly captured his philosophy for the company.
