Quick TakeThis watch isn't just telling time; it's narrating an astronomical event right on your wrist! The Space Timer Supernova explodes with detail, starting with that killer two-tone dial – half shimmering silver, half deep black, both hand-guilloched like a cosmic wave rippling outwards. It feels like watching a planet emerge from the void. Then you get those vibrant red ITR2 rings, looking like captured energy flares, framing the off-center hours and the cool "Open Gear" peek into the movement's heart at 12 o'clock. And check out the moonphase at 6! It's not just printed; it's a floating titanium sphere, glowing with Super-LumiNova, turning the complication into a miniature celestial body orbiting the dial. Even the date uses tiny steel balls embedded in ITR2. The whole thing sits in a tough, matte grey 44mm steel case that feels serious but looks stellar. With the automatic C.308 ticking away inside and limited to just 50 pieces, it’s a genuinely unique slice of horological space exploration.

DescriptionThe Chronoswiss Space Timer Supernova, reference CH-9343M.2-SIBK, features a robust case architecture constructed from 17 individual components. Fabricated from stainless steel, the case presents a matte grey finish achieved through meticulous surface treatment. Geometric specifications define its substantial presence: a diameter of 44 mm and a height of 15.2 mm. The lug-to-lug dimension measures 53.5 mm, accommodating a standard 22 mm lug width. Partial knurling adorns the case flanks, enhancing tactile engagement. Protecting the dial is a curved sapphire crystal treated with a double anti-reflective coating to maximize legibility under various lighting conditions. The screw-down case back incorporates a satin finish and features an integrated sapphire crystal exhibition window, permitting observation of the movement within. An onion-style crown facilitates winding and time-setting operations. Water resistance is rated at 10 bar, equivalent to 100 meters, ensuring protection against water ingress during surface water activities. Strap attachment is secured via the patented Autobloc system, utilizing screwed strap holders for enhanced security and reliability.

Powering the Space Timer Supernova is the Chronoswiss Kaliber C.308, an automatic mechanical movement measuring 32.8 mm in diameter. This caliber operates at a frequency of 4 Hz, corresponding to 28,800 vibrations per hour (A/h), and incorporates 33 jewels to minimize friction at critical points within the gear train. An Incabloc shock protection system safeguards the delicate balance assembly against impacts. The movement provides an approximate power reserve of 42 hours when fully wound. Finishing details include a polished pallet lever, escape wheel, and screws. The bridges and plates exhibit perlage decoration. Further enhancing the visual appeal is a skeletonized rotor, treated with galvanic black coating and adorned with Cotes de Geneve striping, rotating on a ball bearing system for winding efficiency. The time display deviates from a traditional central layout, featuring off-center hours positioned at 12:00, integrated with an "Open Gear" mechanism that exposes part of the underlying mechanics. Central hands indicate the minutes and seconds, while a moonphase complication resides at the 6:00 position. The dial itself is a complex assembly of 63 distinct parts. For the Supernova model, the dial base features a two-tone, hand-guilloched pattern, bisected into silver and black sections. Skeletonized train wheel bridges with angled and polished edges, vertical satin finishing, and sandblasted surfaces contribute to the intricate aesthetic. Transparent, polished, colored ITR2 composite is utilized for the partly skeletonized hour and minute indications. Minute markers are formed from massive cylinders composed of a Super-LumiNova and ceramic mixture. Stainless steel balls, each 0.6 mm in diameter, serve as date indicators, mounted within the ITR2 structure. The moonphase display employs a thermally colored titanium hemisphere featuring Super-LumiNova indicators for the moon and stars. The hands are rhodium-plated with a matte finish, featuring Super-LumiNova inlays and tips for low-light visibility; they follow the "Blade" shape design profile. The strap provided is crafted from shrunk black calf leather. Production of this model is restricted to a limited edition of 50 pieces.
