Experience the Universe on Your Wrist: Precision Meets Celestial Beauty

A Celestial Tribute: Embracing the Legacy of French Watchmaking at the Besançon Observatory

In the realm of exquisite timepieces, Yema proudly presents its Millésime 2026 limited edition, the Spacegraf Heure Sidérale Tourbillon Volant. This extraordinary watch is a universe-inspired creation, meticulously designed to honor the venerable tradition of French watchmaking. It draws profound inspiration from the Besançon Observatory, an iconic institution established in 1878 with the sole purpose of enabling local watchmakers to calibrate their instruments by the precise movements of celestial bodies. The Spacegraf encapsulates this historical essence by featuring a dedicated disc that mirrors the actual rhythm of the night sky, a sidereal time complication that vividly displays the stars visible overhead, bringing the cosmos directly to the wearer's wrist.

Illuminating the Cosmos: A Luminous Dial and Celestial Display

The display of time on this magnificent watch is both elegant and highly legible, featuring two prominent hands and a dual chapter ring system. One ring is intricately notched and three-dimensional, gracefully extending to frame the captivating flying tourbillon, while the other presents a more conventional railroad-track scale adorned with Arabic numeral minute markers. What truly sets this timepiece apart is the application of Grade X1 Super-LumiNova BGW9 across all these elements, including the raised applied ring and the substantial appliqués on the hands. This ensures a profound glow that emanates from their full depth. Even the celestial disc itself is entirely luminous, transforming the watch into a wearable, glowing sky.

Engineering Excellence: Titanium Craftsmanship and Advanced Movement

The Yema Spacegraf Heure Sidérale Tourbillon Volant Limited Edition boasts a case meticulously crafted from grade 5 titanium, measuring a substantial 42mm in width yet impressively slender at just 12.15mm thick. This remarkable slimness is particularly noteworthy given the intricate complexities of the dial's construction, which incorporates both a sky disc and a flying tourbillon. The watch is protected by a double-domed sapphire crystal on the front, while a flat sapphire crystal on the rear offers a captivating view of the CMM.32 Calibre Manufacture Morteau 32. This sophisticated movement delivers an outstanding 105-hour power reserve, offers 5,000G shock resistance in all directions, and orchestrates the flying tourbillon and celestial vault disc. Its plates and bridges are finished in a striking blue hue, further echoing the celestial theme.
