KS 05 timepieces Collection

The KS 05 Collection encapsulates Kross Studio's aptitude for revolutionary timekeeping while maintaining the core principles of traditional watchmaking. This collection heralds a transformative era in luxury timepieces, effortlessly merging artistic craftsmanship, pioneering engineering, and distinctive personal expression. The KS 05 Gold Black Aventurine Full Pavé watch features a 45mm brushed 18 carats pink gold case housing a blue aventurine glass triptych dial and the manufacture's iconic movement, the central floating tourbillon.

KS 7'005 Caliber

A manual winding mechanical movement, the KS 7’005 counts 220 components including 27 jewels, and its construction provides exceptional performance. The main functions such as winding, energy accumulation, regulation, and display are coaxial and placed on the central axis. Thus, the barrel, whose diameter is larger than the radius of the plate, gives the movement a power reserve of 120 hours with chronometric performance.

The balance wheel overlooks the barrel, just like the tourbillon and its fixed seconds wheel, which are elevated above the movement and hands. A patented technical innovation, Kross Studio's central floating tourbillon offers a unique perspective on its complex mechanics.

Peripheral time display

The innovation of the KS 7’005 movement also lies in the peripheral hour display mechanism, achieved by a planetary gear system mounted on two ball bearings, freeing the tourbillon from any obstruction.

The Dials

The KS 05 collection offers striking and precious dial variations, each unique iteration composed of several elegant and functional outer and inner sub-dials.

The outer dial, known as the rehaut, is affixed directly onto the case. It carries the time markings and indices, designed here by Kross to promote a highly legible, Instant reading of the time at a glance. Its design and position offer a seamless aesthetic transition from the case to the watch's interior, drawing the eye towards its groundbreaking central floating tourbillon.

The intermediate dial is mounted on top of the movement, specifically on the fixed hour wheel. It serves as a harmonious bridge between the outer dial and the heart of the watch.

The inner dial, designed with an opening at 9 o'clock, is fixed onto the main plate of the movement. Positioned beneath the floating tourbillon and the time display mechanism, this innovative dial design allows a clear view onto the gear train and sets a captivating backdrop for the tourbillon, adding depth and setting a visual stage to display the watch's meticulous engineering

Each sub-dial is crafted of Black Aventurine glass, giving the watch a nice shimmering touch. Black aventurine is made of coloring agent, silica, copper oxide and other metal oxide blended. Its flecked appearance and sparkling effect come from the combination, heated and cooled down process of the materials. Once the glass has sufficiently cooled and solidified, it can be shaped and polished to be placed within the dial. 

This full process ensures that each timepiece can be considered a unique work of art and engineering.

The 45mm Case

The case is crafted from 18-carat pink gold case and adorned with 281 pavé-set D-F VVS1 diamonds, for approximately 5.09 carats. Its circular satin finish lends it an elegant and modern aesthetic while providing a pleasant tactile sensation. Devoid of lugs, angles, or even a crown, the case presents a sleek profile that offers an ergonomic wearing experience.

The KS 05 watch’s domed and oversized sapphire crystal has received full technical attention: an anti-reflective coating has been applied to both its outer and inner surfaces and anti-UV and anti-static treatments have been applied inside the crystal, making it nearly invisible.

A push-button for setting the time is integrated at 3 o'clock. Ingeniously integrated into the case back and seamlessly interacting with the movement, a D-ring allows for easy and efficient winding of the movement and time adjustment.

The watch showcases Kross Studio's passion for exceptional engineering with its striking and uniquely constructed movement.

Case back

On the back of the case, the Studio's signature cross emblem is delicately emphasized on the barrel bridge. The fully skeletonized design provides a deep insight into the meticulously detailed components. 

The case incorporates a one-click interchangeable strap system, hidden on the case back, which allows the wearer to swap and update their watch strap with ease.
