SWISS MADE - BITCOIN ENABLED

[SUPERNOVA @TheSupernovaEx]

The SN 2140 takes the form of a Grade 5 titanium cushion case whose polished, brushed and sandblasted surfaces interact subtly with the light. Its restrained profile is made possible by the use of an elaboré-grade ETA 2892 movement.

[SUPERNOVA @TheSupernovaEx]

The SN 2140 is purely mechanical in design, it discreetly integrates Lightning payments for everyday transactions.
Lightning combines instant settlement, low fees, and strong transactional privacy, making it one of the most privacy-preserving mainstream digital payment networks.

[NFC SUMMIT - JUNE 4-6 2026 - LISBON @NFCsummit]

Solo shows. Gallery presentations. Community displays. NFT preservation. A book launch. A generative series inspired by Lisbon's tilework. 🇵🇹

The Rare Art floor at NFC Summit 2026 is open - and it's asking: how many ways can digital art be shown?

[SUPERNOVA @TheSupernovaEx]

We were honored to partner with @CVConf_ event and introduce the SN 2140 to a remarkable audience of entrepreneurs, builders, and institutional leaders shaping the future of blockchain.
The reception was incredibly positive, and the event created many opportunities.

🤯 J'ai trouvé une faille spatio-temporelle vers 2016 à la télévision !

Tous les poncifs (ou presque) sur #Bitcoin dans UNE émission, en moins de dix minutes !

- Bitcoin n'est pas une monnaie
- Bitcoin ça détruit la planète
- Bitcoin c'est de la spéculation pour enrichir très peu de gens
- Bitcoin c'est pas une valeur refuge, parce que ça a perdu 5% l'an dernier
- Bitcoin n'a pas de valeur parce que y'a pas de dividendes
- Bitcoin c'est nul, le vrai truc, c'est LE #blockchain

En 2026, il existe encore une personne sur terre qui dit encore "le" blockchain !

Et sinon, pour la qualité du débat public, on pourrait avoir des contradicteurs compétents ?

Non parce que dans le même temps, aux Etats-Unis, BlackRock, Morgan Stanley ou encore Goldman Sachs sont passés à la recommandation et la fourniture de services Bitcoin à leurs clients, tandis que le pays lui-même a constitué une réserve stratégique.

Watchmaking & Privacy.

[SUPERNOVA @TheSupernovaEx]

A mechanical watch that integrates the most private contactless payment feature.

[SUPERNOVA @TheSupernovaEx]

Pre-orders. New connections. New perspectives.
Grateful for the response to SN 2140 at @ParisBlockWeek and @watcheswonders

[Ju Lewski @LewskiSupernova]

From Paris to Geneva. Let's go.

[SUPERNOVA @TheSupernovaEx]

@ParisBlockWeek was unreal. Thank you!
Now Off the Geneva for @watcheswonders. Join us at our discovery Pop-Up downtown. Details and registrations here: https://t.co/vly7jzsuOc

Finishing is treated as a tool of articulation rather than embellishment.
Matte textures guide the eye across surfaces. Polished accents mark transitions and edges. Brushed planes reveal form and geometry.
Finishing does not decorate the object. It clarifies it.
