■ Spiral pattern dial expresses the galaxy
The biggest appeal of the SBXY105 is the dial, which features a newly developed "spiral pattern" stamping pattern. The spiral pattern that spreads out from the center of the dial is reminiscent of young stars swirling to form a galaxy, conveying the energy of flowing stars.
The all-black case and bracelet and the dark turquoise (deep blue-green) lame dial express the image of a swirling galaxy emerging in the pitch-black universe.
With a finish that changes its expression depending on the angle of light, it gives your wrist a presence that is unique to a limited edition model. This special design allows you to wear the mystery and grandeur of the universe on your wrist.
■ Overwhelming presence of all black
The case and bracelet are made of lightweight and rust-resistant titanium material, making them comfortable to wear, and the surfaces are coated with a hard black coating to prevent scratches.
The all-black design expresses the jet-black universe. The finish gives it a futuristic and sporty impression, while still maintaining its luxurious feel.
The center piece of the bracelet has a mirror finish, creating a lustrous design that is linked to the brilliance of the galaxy. The sparkle of the mirror surface in black is truly beautiful and reminiscent of a starry sky.

■ Buyer's comment
The moment I picked up the SBXY105 for the first time, I was overwhelmed by its overwhelming presence. The all-black design is really cool, and the concept of jet-black space is perfectly realized. The dark turquoise glitter dial is beautiful, and I never get tired of watching it change its appearance depending on how the light hits it. The newly stamped ``Spiral Pattern'' is truly wonderful, and the spiral pattern that spreads out from the center of the dial truly represents the appearance of a swirling galaxy. Just by looking at the dial, you can feel the concept of young stars swirling around to form a galaxy. The center piece of the bracelet has a mirror finish, and the sparkle in the black color is just like a starry sky. You can really see that the design is linked to the brightness of the galaxy. The titanium case and bracelet are incredibly light, and at just 90g, it's incredibly comfortable. It's much lighter than stainless steel, so you won't get tired even if you wear it for a long time. It has a hard black coating, so you can rest assured that it won't get scratched. Equipped with solar radio correction (standard radio wave reception) caliber 8B92, it displays accurate time no matter where you are in the world. The world time function supports 25 time zones, which is a really convenient feature for those who often travel overseas. The chronograph function is also complete with a 1/5 second measurement and a 60 minute timer, making it useful in sports situations. It is surprising that the fully automatic calendar function is compatible until 2099, giving you peace of mind that you can continue using it for a long time. It is water resistant to 10 ATM, so you can use it with confidence even when working in the water or light swimming, and the super clear coated sapphire glass provides high visibility. Lumibrite makes it easy to see even in dark places, which is also practical. The smart adjuster mechanism allows you to conveniently adjust the size without the need for tools, making it easy to adjust to suit the scene. It also has metal allergy resistance, making it gentle on the skin. With reliable quality made in Japan and a 3-year manufacturer's warranty (Nanapure is running a 7-year warranty campaign), you can use it for a long time with peace of mind. It has a special feel as it is limited to 700 pieces, and the serial number and LIMITED EDITION notation on the back enhance the joy of owning it. I think this is a truly special piece that allows you to wear the swirling galaxies of the magnificent universe on your wrist. by Fujimuro
