Pupil Ultralight, distilling the magnificent artistry of the ancient Shu civilization from three thousand years ago and underpinned by cutting-edge material innovations along with structural breakthroughs, is forged into a slender and lightweight silhouette. It bears a gaze that spans millennia and perceives all things between heaven and earth, embodying a profound spiritual philosophy. Thus the majestic spirit of an ancient civilization flows endlessly upon the wrist.

The awe-inspiring power of the ancient Shu civilization has turned the brand’s exploratory gaze toward the mysterious Sanxingdui. 

As the most iconic cultural symbols of Sanxingdui,the magnificently

 shaped, surreal“Protruding Eyes” stand as artistic treasures forged by the creativity of the ancient Shu people.

This timepiece incorporates the distinctive geometric wisdom

 of the ancient Shu civilization into its layout design. 

Drawing inspiration from the rhomboid geometric form of the

 "Bronze Diamond Eye", it extracts their acute and obtuse angles as 

the core logical basis for the watch’s mechanical layout.

 Through the exquisite arrangement of movement components

a visual rhythm of interlaced obtuse and acute 

angles is formed along the left-right direction of the dial,

interpreting an Eastern geometric cadence that

 combines a sense of power and balance within the limited space of the wrist.

The form of the "Bronze Diamond Eye" is transformed into the design of

the hour and minute hands. As time progressesthe hour and minute hands 

glide within the meteorite chapter ring,drawing and responding to each other. Amid constant disassembly and reorganization the rhombic "Bronze Eye" 

emerges and fades repeatedly. Each intersection of the 

hands is unique—it engraves not only the marks of timebut also the total sum of "disorder" continuously accumulated in the flow of  titime: "entropy".

The watch features BEHRENS’ iconic "Hu"-shaped case, achieving a groundbreaking integrated design of the movement and the case. 

At the same time, it integrates cutting-edge material innovation,

adopting a Lightweight Monolayer Graphene Hybrid (LMGH)

 introduced for the first time. Excluding the strap

 the total weight is only about 8 grams—light as flowing 

clouds the moment it touches the wrist

 fitting naturally with the curve of the wrist. 

The integration of platinum foil infuses the single base color 

with a cool silver luster, revealing a modern,

pioneering technological sense and minimalist elegance.

It is equipped with the brand’s all-new self-developed Cal.BM09 manual-winding movement. The upper left corner of the dial is equipped with a power reserve display function, whose pointer design is also inspired by the "Bronze Diamond Eye". The hour hand at the lower right corner of the dial adopts an instantaneous jump display method—when the minute hand completes a full circle, the hour hand immediately jumps to the next hour.

The lower left corner of the dial is equipped with a day-night 

display function, taking the "Sun and Immortal Birds Gold

 Ornament" as the symbolic image of the "sun" representing daytime. 

As time flows, this ancient symbol operates slowly on the dial, 

ecreating the ancient Shu people’s worldview

 of sunrise and sunset, and the cycle of light.

 Amid the precise rhythm of the mechanism,

it awakens the echo of faith that has spanned thousands of years.
