A bubble of privacy
on the wrist.

What matters most about the SN 2140 is not what it does, but what it lets you keep to yourself.

01 · The Object
One watch

Two systems.
One object.

The watch

A Swiss mechanical movement, first.

Self-winding, visible through the sapphire caseback. Nothing to charge.

The capability

A discreet way to move value privately.

No screens, no interfaces, no accounts. There when you want it, and otherwise out of sight.

Two aspects of one object. Neither takes the lead.

02 · Powered by You
Neither needs the other

Nothing to charge.
Nothing to subscribe to.

The SN 2140 caseback, the rotor visible through its sapphire window
The movement

It winds itself.

A rotor turns with the wrist and stores the energy. Forty-two hours in reserve, no battery, no cable, nothing to remember.

The capability

You top it up when you choose.

Add a balance over Lightning or on-chain, in the amount you decide. Nothing is topped up automatically, and nothing is held for you.

Two systems, and neither waits on the other.

03 · Adjustment
What you control

Set by hand.
Held in your own name.

The SN 2140 in profile, showing the crown
The movement

The crown, and nothing else.

Pull, turn, push. The same gesture watchmaking has used for a century, on a crown small enough to disappear into the case.

The capability

Your balance, your limits.

The cap is CHF 1,000 at top-up. No account is created, and no personal data is stored on the watch.

Both are adjusted by the wearer, and by nobody else.

Two systems

Neither was added
afterwards.

The SN 2140 is not a mechanical watch with technology bolted on, nor a technology product dressed as a watch. It was drawn as one object from the beginning.

04 · In use
Reading and paying

Tell the time.
Or settle the bill.

The dial lit for a contactless payment
The movement

A glance.

Circular-brushed dial, Super-LumiNova® on the hands and markers, legible at arm’s length and in the dark.

The capability

A touch.

Hold the watch to a terminal that supports the Bolt Card standard for BTC Lightning payments. There is no screen to wake, no app to open and no code to enter.

One object, used two ways, neither announcing the other.

05 · Engineering
Two years of it

An antenna discreetly integrated
in the sapphire glass.

The sapphire crystal lit from within
The movement

ETA 2892, élaboré grade.

28,800 vibrations an hour, 42 hours of reserve, blued screws and Geneva stripes, visible through the sapphire caseback.

The capability

Two years of research and industrialisation.

A custom antenna and contactless chip integrated directly into the sapphire, developed with STISS over two years of research and industrialisation. It is invisible to the naked eye.

Both were engineered to the same standard.

06 · Swiss Made
Where it is made

Federating the best experts from the
French-speaking part of Switzerland.

The SN 2140, assembled in Le Locle
The movement

A Swiss watchmaking ecosystem.

Assembled in Le Locle, in the heart of Swiss watchmaking. Swiss Made, and made by people who have been doing it for generations.

The capability

Swiss Bitcoin Pay.

Payments are processed by Swiss Bitcoin Pay, a FINMA-registered provider based in Neuchâtel. The watch is not a banking service, and we are not one either.

The same country, and the same expectation of care.

Why it matters

A conversation piece
you control.

It says nothing until the wearer opens the door. Another way exists, and choosing it still counts for something.

Reserve yours

Everything else is on the wrist.

See how the idea becomes an object: the case, the movement, the materials.
