uspended between Earth and cosmos, its heart beats within its own sealed realm: a mechanical orchestra enclosed in a perfect void. In this watch, the absence of air becomes the guardian of precision.

In 1959, Century’s visionary founder Hans Ulrich Klingenberg posed a daring question: « What if the beating heart of a mechanical watch could be completely isolated from the world around it? »

His answer became a horological milestone: the Vacuum technology, a hermetically sealed case that preserved the movement in an air-free chamber.
In Mastersphere, this revolutionary concept returns — refined, enhanced, and more beautiful than ever.

The original vintage case and movement have been revived, while the bracelet, hands, and dials have been redesigned to express contemporary elegance.

At its core beats a high-frequency automatic calibre (36,000 vib/h) based on the ETA 2837, re-engineered in-house for unparalleled precision and a fluid, continuous sweep.

Mastersphere’s hermetically sealed monobloc case forms an immaculate sanctuary, isolating the movement from dust, humidity, and oxygen — even from the “wear of time” itself.
Its 24-facet Century sapphire glass, part of Century’s identity, completes the architecture of a perfect sphere. Available in three metallic dials — deep black, sky blue, and golden brown — the design fuses vintage soul with avant-garde craftsmanship.
Each piece bears the engraving “Limited Edition – One of 88.”

Like a black hole capturing light, Mastersphere defies time and the erosion of Time.
Its hermetically sealed environment ensures uncompromising precision, permanent lubrication and absolute protection — guaranteed worldwide with a 3-year warranty, extendable to 5 years.

A watch of cosmic inspiration and timeless allure, Mastersphere embodies the spirit of modern explorers — those who seek beauty in precision and silence in motion.
