Description
SEIKO ASTRON NEXTER DYNA SBXY063
The SEIKO ASTRON NEXTER SBXY063 is a Japanese Domestic Market solar radio-controlled watch featuring a black patterned dial and lightweight titanium construction. Its compact, angular exterior combines the forward-looking character of the NEXTER series with the dynamic design concept commonly identified as DYNA.
Dynamic NEXTER Design
The SBXY063 combines a multifaceted titanium bezel with a solid, sharply defined case and an integrated three-row bracelet. Contrasting brushed and polished surfaces emphasize its angular construction while maintaining a clean appearance suitable for a broad range of settings.
The black dial features a pressed pattern inspired by quartz crystal, referencing the original Quartz Astron introduced in 1969. LumiBrite on the hands and indexes supports visibility in low-light conditions without interrupting the watch’s restrained dial layout.
Solar Radio-Controlled Caliber 7B72
SEIKO Caliber 7B72 converts light into electrical energy and automatically corrects the time by receiving terrestrial standard-time radio signals. Reception is supported in Japan, China, the United States, Germany and the United Kingdom.
When fully charged, the watch operates for approximately nine months under normal conditions or approximately two years when power save is activated. If no radio signal is received, its stated accuracy is an average of ±15 seconds per month when worn at temperatures from 5°C to 35°C.
Automatic Time and Calendar Functions
The movement provides automatic and manual signal reception, reception-result display, time-difference adjustment and automatic hand-position correction. Its full-auto calendar is programmed through December 31, 2099. Additional functions include quick start, overcharge prevention and power save.
Lightweight Titanium Construction
The case and bracelet are made from lightweight, corrosion-resistant titanium and treated with SEIKO’s DiaShield surface protection. The case measures 45.4 mm in length, 39.6 mm in width and 9.5 mm in thickness, with a total weight of approximately 90 g.
A sapphire crystal with Super Clear Coating reduces reflections for improved dial visibility. The bracelet is secured by a push-button three-fold clasp equipped with SEIKO’s Smart Adjuster mechanism, allowing convenient fine adjustment. The watch provides enhanced water resistance for daily use at 10 bar and confirmed magnetic resistance.
Japanese Domestic Market Model
SBXY063 is a reference developed for the Japanese domestic market and is distributed through SEIKO’s Japanese product and retail channels. The JDM designation identifies its intended market and is separate from the country of manufacture; authorized Japanese retail information identifies this model as manufactured in Japan.
