Design Concept: All-Black with Black Moissanite
The “Black Phantom” collection is characterized by its unified black aesthetic, extending from the case to the strap. Each black moissanite stone is meticulously set into the bezel, creating a rich, deep black presence. This collection aims to redefine black models by meticulously focusing on the material texture and finish, resulting in a distinct and understated elegance.

HATCH-BEZEL® Feature
Equipped with the patented “Hatch Bezel” mechanism, the Apple Watch can be easily inserted or removed with a single touch. This feature allows users to switch cases effortlessly depending on their preference or occasion, and also simplifies cleaning.

BLACK MOISSANITE Details
The black moissanite stones set in the bezel offer a unique combination of high refractive index and a deep black tone. These stones absorb light, yet subtly reflect it at certain angles, adding a delicate and sophisticated accent to the all-black design.

World Limited 99 Pieces
This collection is a special limited edition, with only 99 pieces produced worldwide. Each piece is distinguished by a serial number engraved from 1 to 99 on its back case, emphasizing its rarity and unique value.

CRYSTAL BOX Packaging
The “Black Phantom” comes in a stylish, semi-transparent black clear box. This packaging is designed to enhance the unboxing experience, offering more than just a container but a special moment of anticipation.

Customize Your Style with Black as the Base
The overwhelming sense of unity created by the all-black design offers enduring appeal. For those who wish to personalize their watch further, interchangeable straps (sold separately) can be used to update the style.
