Every so often, a star appears where there wasn't one before. For a few nights it outshines its neighbors. Then, over weeks and months, it slowly fades back into the dark.

Chinese court astronomers watched for these visitors for centuries and called them guest stars: not residents of the sky, just passing through. In 1572, the Danish astronomer Tycho Brahe spotted one and called it stella nova, the “new star.” The name stuck.
The Milifortic AD36S140 is built around that moment.
A star that comes back
Here's the part that stayed with us: a nova isn't a new star at all. It's an old one.
It begins with a white dwarf, the dense core a star like our Sun leaves behind when it burns out. When a white dwarf has a close companion, its gravity pulls gas from that star. The gas builds up on the white dwarf's surface until it ignites, and the dead star flares thousands of times brighter than before.

The explosion doesn't destroy it. The white dwarf survives and gathers gas again, and some flare again within a single human lifetime.
One of them, T Coronae Borealis, sits about 3,000 light-years away. It flared in 1866 and again in 1946, and astronomers have spent the past few years watching for its next return. When it returns, a star normally invisible to the naked eye will shine about as bright as the North Star for a few days.

That idea of a comeback became our design brief. We spent weeks with photographs of novae: a bright core, light spiking outward, color falling away into black at the edge of the frame. Then we asked whether that moment could be pressed into a watch dial.
Pressing a flare into a dial
The answer is a dial stamped in three-dimensional relief. Raised rays burst from the center and run unevenly toward the edge, more like a flash of light than a machined pattern. As your wrist moves, light catches the ridges and the burst seems to shift.

On the purple and dark blue dials, the color is brightest at the center and deepens toward the edge, the way a flare fades into the night around it.
Around the burst, round applied indices filled with C3 lume sit like scattered stars. Bars at 12, 6 and 9 hold the layout steady, like the cardinal points on a star chart. The date window takes the fourth spot, at 3.
Faceted, lumed hour and minute hands sit above it all. The seconds hand carries a small lollipop disc that circles the dial like a satellite tracing its path overhead. When the lights go down, the C3 lume takes over and the dial becomes a small night sky of its own.
Four skies
The AD36S140 comes in four dial colors, each a different view of the same night:
- Black: deep space, the quiet dark before the flare.
- Dark blue: the sky just after dusk, when the first stars come out.
- Ice blue: the cold blue-white light of the brightest stars.
- Purple: the violet glow of a nebula in a long-exposure photograph.
Built for every day
Behind the story is a compact sports watch that suits a wide range of wrists. The 316L stainless steel case is 36mm across (38.6mm with the crown), 43.5mm lug to lug and about 10.3mm thick.
A sapphire crystal with anti-reflective coating, a screw-down crown etched with our logo and a screw-down caseback give it 100m (10 ATM) of water resistance. Inside is a Seagull ST2130A automatic movement showing hours, minutes, seconds and date.
The three-link stainless steel bracelet closes with a 316L double push-button folding clasp, also etched with our logo. The 20mm lugs make strap changes easy. On the bracelet, the watch weighs about 135g.
Available now
The AD36S140 is available now in black, dark blue, ice blue and purple. Some stars shine once and disappear. A nova comes back.
