ONE SKY. ONE DIAL. NEVER REPEATED.
Exact astronomy, pad printed for one owner.
We calculate the visible stars and constellation geometry for your coordinate, date and local time from astronomical data, then engineer that sky as production artwork for your chosen dial size. A dedicated pad printing cliché is produced for your watch alone.
The map is transferred by precision pad printing, the process used for fine detail on high-end dials, then completed through a four-stage print-and-lume process: the initial precision print followed by three registered applications of Swiss BGW9 Super-LumiNova. No two ChronoAstra dials carry the same sky.

DEEP SPACE ENAMEL
Near-total black. Maximum celestial contrast.
Blackout uses ChronoAstra's ultra-black enamel finish to create an uninterrupted celestial field. With no aventurine sparkle, texture or colour to compete, the stars and constellations appear suspended in darkness. The effect is graphic from a distance and extremely precise up close, where every line belongs to a sky generated for one owner and one moment.
The custom artwork is individually prepared and precision pad printed rather than applied as generic stock artwork. BGW9 Super-LumiNova turns the map into a soft blue constellation after dark.
THE MATERIAL ITSELF
Ultra Black Enamel
Glass-like depth.
Every Blackout begins with this surface. The blank is inspected, then the sky of your exact moment is precision pad printed onto it and completed with three registered applications of Swiss BGW9 Super-LumiNova.
BLACK DLC GRADE 5 TITANIUM
Built from titanium. Finished in shadow.
Blackout's Grade 5 titanium case and integrated bracelet require hours of hand finishing across dozens of surfaces before DLC is applied. Satin planes, mirror-polished bevels and recessed elements remain distinct beneath the coating, creating an architectural range of blacks rather than a single flat tone. The coating adds enhanced scratch resistance while the light weight of titanium keeps the watch comfortable.
The same Grade 5 titanium architecture is brushed and mirror-polished by hand before receiving its black DLC coating. The coating adds enhanced scratch resistance without erasing the finishing beneath it: satin planes, polished bevels and recessed surfaces remain visible as subtle shifts between graphite, ink and reflected light.
WHY THIS PAIRING
When everything else disappears, your story remains.
Blackout is the collection reduced to its essential idea: a personal sky, luminous against darkness, held in a case whose complexity is felt before it is fully seen.

YOUR MOMENT, FOREVER ETCHED
Individually etched with your details into the caseback.
Your exact date, time, coordinates and chosen word are individually etched into the caseback. The reverse of every Blackout carries the coordinates, date and local time of your moment, plus up to twelve capital characters of your own text: a name, a place, a single word. It is etched into the titanium, not printed on it.
Quartz builds receive a solid titanium caseback. Automatic builds receive a sapphire display back, with your individually etched details framed around the movement.
