■ Spiral pattern inspired by a swirling galaxy
The biggest appeal of the SBXY107 is that the dial has a newly developed "spiral pattern" stamping pattern. The spiral pattern that spreads out from the center of the dial perfectly depicts young stars swirling around to form a galaxy. The magnificent and mysterious design that conveys the energy of falling stars is attractive.
The dark turquoise-based glitter dial represents the image of a swirling galaxy emerging within the jet-black universe. The combination with the all-black case and bracelet perfectly expresses the grandeur and mystery of the universe. The glitter shines depending on the angle you view it from, giving it a sense of depth and three-dimensionality, just like a real galaxy.
The texture of the spiral pattern is really high quality, and you can feel the attention to detail. The spiral pattern on the surface of the dial changes its appearance depending on how the light hits it, and you discover something new every time you look at it. The rarity of this model, limited to 700 pieces in Japan, makes this model even more special.
■ All-black fearless design
The case and bracelet are made of lightweight and rust-resistant titanium material. The surface is coated with a hard scratch-resistant black coating, creating a fearless design inspired by the jet-black universe. The all-black uniform gives it a modern and sophisticated look.
The central piece of the bracelet has a mirror finish, creating a lustrous design that is linked to the brilliance of the galaxy. The contrast between the matte black coating and the mirror finish is beautiful, giving the entire bracelet a sense of depth and luxury. This attention to detail speaks to Astron's high level of quality.
■ Light and comfortable to wear due to titanium material
By using titanium material, we have achieved a lightweight design of approximately 82g. Even if you wear it for a long time, you won't get tired and it's comfortable to wear. Titanium also has the property of being resistant to rust, so it is a material that can be used safely even on a daily basis.
The bracelet's clasp uses a "smart adjuster mechanism" that allows you to easily fine-tune the length of the bracelet without using tools. This is a convenient feature that can accommodate changes in your arm circumference depending on the season. It can fit an arm circumference of up to 19.5cm, so it will fit a wide range of people.
■ Radio-controlled solar compatible with Japan, China, the United States, and Europe
Equipped with a radio wave correction function that receives standard radio waves from Japan, China, America, Germany, and the UK. The automatic reception function regularly adjusts the time, so it always keeps accurate time. It also has a forced reception function and a reception result display function, making it extremely easy to use.
The time difference correction function allows you to easily adjust the time when traveling abroad or on business trips. The automatic needle position correction function automatically returns the needle to the correct position even if it is misaligned due to magnetism or impact, so you can use it with confidence in your daily life.
■ Long-time operation of about 9 months when fully charged
Equipped with the solar radio-modified 7B72 caliber, it can run for about 9 months when fully charged. Since it can be charged using sunlight or indoor light, you can save yourself the trouble of regularly replacing batteries. The power save function automatically switches to power saving mode in dark places and continues to operate for about 2 years.
Another great feature is that the overcharge prevention function keeps the battery in optimal condition. The instant start function allows the clock to start running as soon as you expose it to light, so you don't have to worry about it even after not using it for a long time.
■ Fully automatic calendar compatible until 2099
Fully automatic calendar function eliminates the need for calendar adjustment until December 31, 2099. It also automatically adjusts for leap years, so you don't have to worry about setting the date at all. With an average monthly difference of ±15 seconds, the accuracy is reliable even in environments where radio waves cannot be received.
Lumibrite is used for the hands and indexes, so you can check the time even in dark places. The sapphire glass has a super clear coating that suppresses light reflection and improves visibility.
■ 10 ATM water resistant, safe for daily use
It has a reinforced waterproof function for daily life of 10 ATM, so you can wear it with confidence even when working in the water or on rainy days. It also has anti-magnetic properties, so it is resistant to magnetic fields encountered in daily life. It is metal allergy resistant, so even those with sensitive skin can wear it with confidence.
The back cover is engraved with the words "LIMITED EDITION" and the serial number, giving it a special feel as a limited edition model. The 6-jewel movement supports highly accurate time display.
■ Reliable quality made in Japan
We are proud of the high precision and quality that can only be achieved by being made in Japan. This model, which brings together Seiko's technology, has a finish that shows attention to detail. The reliable quality that you can use for a long time will be a great companion to your daily lifestyle.
A three-year warranty is provided by the manufacturer, and after-sale service is also available. Nanapure is running a 7-year warranty campaign, so you can use it for a long time with even more peace of mind.

■ Buyer's comment
I was overwhelmed by the beauty of the spiral pattern of SBXY107.
The spiral pattern that spreads out from the center of the dial is truly exquisite, and perfectly depicts young stars swirling around to form a galaxy.
The dark turquoise laminated dial perfectly recreates the galaxy shining in the pitch black of space.
The lightweight design is made of titanium material and weighs approximately 82g, so you won't get tired even if you wear it for a long time.
The mirror finish of the middle pieces of the bracelet is glossy, and the contrast with the matte black coating is beautiful.
The radio solar function supports 5 areas, and the practicality of running for about 9 months when fully charged is also great.
This is a special piece, limited to 700 pieces in Japan. by Fujimuro
