Hublot Big Bang Tourbillon Automatic Green SAXEM - LVMH Watch Week 2025 #LVMHWatchWeek2025
By SENATUS Editor | 23 January 2025

Hublot is the first and only watch brand to use SAXEM (Sapphire Aluminium oXide and rare Earth Mineral), a material that’s related to sapphire while offering more luminous and chromatic possibilities, and was originally conceived for satellite technology. While it does boast many of the same properties to sapphire such as hardness and transparency, it’s different on a molecular level. While both are made of aluminium oxide, SAXEM is combined with rare earth elements. Its also structurally different, as sapphire is trigonal (three-sided) while SAXEM is cubic (four-sided). This subtle but significant distinction allows for SAXEM to take on intense colours and shine brilliantly, like a precious gemstone.

For LVMH Watch Week 2025, the manufacture presents the Big Bang Tourbillon Automatic Green SAXEM, combining an intense emerald-green transparent case with its self-winding tourbillon movement in a limited edition of just 18 pieces.

Within the vibrant and crystalline green SAXEM case beats Hublot’s MHUB6035 automatic tourbillon manufacture calibre, entirely developed and manufactured in-house. Built with a contemporary architecture, its 22-karat gold micro-rotor is positioned on the dial side of the movement. The winding is smooth and efficient with ceramic ball bearings, allowing the movement to reach a minimum chronometric power reserve of 72 hours. With an emphasis on openness and motion, the kinetics of the micro-rotor at 12 o’clock is complemented by the 60-second tourbillon carriage at 6 o’clock. The openness of the construction is accentuated by three functional sapphire elements for the barrel bridge, automatic winding gears bridge and tourbillon barrette. Specially for the Big Bang Tourbillon Automatic Green SAXEM, the dial is tinted darker.

The movement itself, visible through the open dial, is finished in black tones, providing more contrast to the SAXEM case and matching the crown. For added legibility, the Big Bang’s signature alternating Arabic numerals and baton markers feature a bright green paint with Super-LumiNova, as do the hands. A mix of sandblasted and hand-decorated elements with polished bevelling sunray-brushing elevates this modernistic and unique take on watchmaking into a true haute horlogerie creation.

As the perfect finishing touch matching the case, the Big Bang Tourbillon Automatic Green SAXEM comes on a transparent green rubber strap and black folding clasp.
