Nixie tube clock with Soviet nixie tubes on a black marble clock case
Nixie tube clocks since 2012

Clocks built on original Soviet nixie tubes

Every clock is hand-built around genuine Soviet nixie tubes made between 1970 and 1990. Marble, brass and solid wood clock cases frame a warm glow from a technology no longer manufactured.

Original tubes only

Production stopped in the early 1990s. We work with what is left.

Every tube in our clocks was manufactured in the USSR between 1970 and 1990. There is no new supply: each tube is a finite object with a history, and we treat it that way. Tubes are replaceable without soldering, so the clock outlives its parts.

Original Soviet IN-14 nixie tubes

24 h on the bench

Every tube is burned in and tested for up to 24 hours before it goes into a clock case.

Warranty up to 7 years

Two years on core models, five on premium, extended coverage on the clock and the tubes.

No longer made

No factory makes these tubes any more. What we hold is the remaining stock.

Up to 30 years of glow

Automatic tube regeneration and controlled voltage keep the cathodes alive far longer.

About us

From a workshop idea to an international brand

Since 2012 we have hand-built over 10,000 clocks and released more than 40 limited collections. We made a clock for Elon Musk to mark the Mars mission, entered the Tretyakov Gallery collection as part of the history of Russian design, and cut a clock case from 10,000 year old mammoth femur for a gallery in the UAE.

Today our clocks live in Russia, the United States, Europe, the UAE, Qatar and Armenia.

What owners say

★★★★★
A rare example of true craftsmanship and reliability

I have owned my Past Indicator Nixie clock for almost three years now… The warm glow of the tubes is mesmerizing and the clock immediately becomes a conversation piece in any room. After almost three years of daily use the clock still works perfectly.

FAQ

Common questions

What is a nixie tube clock?

A nixie clock displays time with cold-cathode gas-discharge tubes. Digits glow inside a glass envelope, producing a warm orange light that no LED or LCD screen reproduces.

Which tubes do you use?

Only original Soviet tubes: IN-12, IN-14 and IN-18, made between the 1970s and the early 1990s. Production ended in 1993, so every tube is a finite object with its own history.

How long do the tubes last?

Up to 30 years in normal use. Our boards extend that further with automatic tube regeneration and precisely controlled voltage and current, which reduces cathode wear.

Can the tubes be replaced?

Yes. Tubes sit in sockets and are replaced without soldering, so servicing is simple and the clock outlives its tubes.

What materials do you use for the clock cases?

Natural and precious materials only. Wood: walnut, oak, ash, thermo ash, padauk, elm, mahogany, wenge, rosewood, lacewood, bubinga. Metal: gold, aircraft aluminum, brass, stainless steel, nickel. Stone: marble, serpentine, onyx, jasper, dolomite. We also work with jeweler's resin, including hand-poured inlays.

What features does the clock have?

Time and date, alarm, smooth or instant digit transition, sleep mode, automatic tube regeneration, adjustable backlight (blue by default, red on request), 12 or 24 hour format and adjustable brightness.

How is it powered?

Through the supplied adapter: 12V to the clock, 100 to 240V mains, so it works in any country with the right plug adapter.

What is the warranty?

Two years on core models and five years on premium models, covering both the clock and the tubes. The exact term is stated in the documents shipped with your clock.

How do I care for it?

Wipe the clock case with a dry or slightly damp soft cloth. Never use cleaners containing acids, alkalis, ammonia or chlorine: they damage wood, stone and metal finishes. Tubes need no maintenance, though sleep mode extends their life.
