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 Titanium Moss Agate watch features a 45mm brushed titanium case housing a moss agate 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 Titanium Moss Agate dial is composed of two distinct parts.

The design and position of the outer dial offer a smooth aesthetic transition from the case to the movement, drawing attention to its revolutionary central floating tourbillon. Circular satin-finished, in black PVD, it features an engraved railway track filled with white lacquer. The indexes are rhodium-plated, satin-finished, and filled with white Super-LumiNova®.

The inner dial, made of moss agate is designed with an opening at 9 o'clock and is fixed on the movement's plate. It allows a glimpse of the fascinating mechanism of the movement and its traditional watchmaking finishes, visible between the filaments embedded in the stone.

Moss Agate

Moss agate forms from mineral deposits within the cavities of volcanic rocks, acquiring a distinctive appearance with filaments or dendrites resembling moss inside. As a specific variety of agate, its transparency can vary depending on the density of the mineral deposits it contains, making each stone unique.

The 45mm case

The case is crafted from grade 5 titanium. 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.
