Description

Innovatively designed, the SB06-24 transforms the passage of time with a unique 24-hour mechanism.

With an additional gear module fitted under the dial, the hour hand runs two times slower and therefore makes only one unique rotation per day. To read the time on the scale, use the sun symbol for daytime hours, and the moon symbol for nighttime hours. Each symbol covers a twelve hour period in a continuous loop.

Use the minute hand to read the minutes as usual.

The center dial of the watch showcases a unique moon with an extraordinary story of craftsmanship. The engraving is based on altimeter measurements from NASA’s Lunar Reconnaissance Orbiter with a scale factor for diameter at 1:155 million and for height at 1:70 million. The topography of the moon is reproduced to a depth of 200 µm with a total engraving of 445 µm depth on a convex-shaped dial surface showcasing an incredible level of detail and dedication to authenticity.

At the heart of these timepiece is Sartory-Billard’s first in-house movement, the SBTV01.

It features an almost invisible top bridge crafted from sapphire that requires skill in handling, revealing detail and giving light and depth to the movement and its unique customizable guilloché base plate. Together with the two arched bridges this movement design allows a maximum of visibility. Embracing the essence of true “Haute Horlogerie”, every component, even those unseen without disassembly, undergoes meticulous finishings like black polished screws, polished chatons, sinked holes and columns.
