【Apple Watch】Summer shines coolly in blue! New luxury case "Golden Concept"
The change of seasons is the change of the Apple Watch case. If you're looking to upgrade now, the blue strap that shines coolly on hot days is recommended.
A vibrant blue that colors your summer travels in luxury!
"GOLDEN CONCEPT" is a luxury Apple Watch case brand from Sweden. As a new summer release, the "SIERRA BLUE EDITION" from the brand's "RACING SPORT" series has been launched.

The carbon case features delicate patterns carved out, and the vibrant blue strap creates a beautiful harmony. The polished silver also serves as an accent. It's a fashion item that will shine even more in the coming season, exuding a dignified presence on your wrist.

A patented unique mechanism called "Hatch Bezel" allows for easy one-touch attachment and detachment. The seamless case changes make it simple to switch to your favorite case for both business and leisure scenes. Cleaning is easy, and daily usability is highly satisfying.

The case material uses "TPC Carbon," a carbon fiber that balances lightweight and strength. This advanced material, used in racing cars, architecture, and watches, has minimized surface area to achieve an even lighter finish compared to traditional carbon products.

The new mechanism "Snap-On Strap" allows for strap attachment and detachment without tools. Combined with a wide variety of replacement straps, it seems you can enjoy a change of image not only in summer but also according to the season, style, and mood. The case is housed in a transparent clear box, and I'm excited about the luxurious unboxing experience that awaits.
