Peripheral time display

The time display mechanism operates peripherally, working around the barrel and the tourbillon mechanism. The peripheral display orbits 360 degrees around the tourbillon, and the reduction ratio between the hour and minute is achieved through a planetary system mounted on two ceramic ball bearings.

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 KS 05 collection represents a new breed of luxury timepieces distinguished by a meticulously crafted case that equally balances functionality and aesthetic appeal.

The crystal also receives Kross Studio's full technical consideration, with numerous treatments applied to promote crystalline legibility in all conditions while protecting the precious watch movement it encases. The domed crystal receives an anti-reflective coating on both its exterior and interior, and Kross Studio also applied anti-UV and anti-static treatments to the crystal interior.

The domed crystal of the KS 05 provides an unobstructed, panoramic view of the watch's inner workings. Its oversized diameter allows the viewer to appreciate the full breadth and complexity of the meticulously crafted movement and the dial rehaut from all angles.

Devoid of lugs or edges, the KS 05 case exhibits a sleek, seamless, and ergonomically optimized profile. Instead of a visible crown at 3 o'clock, Kross Studio opted for a clever D-ring crown integrated into the case back, which enables winding and time adjustments without disrupting the watch's clean lines.

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.
