Math Clock "Albert Clock" Original – Wood · 33 cm | Albert Clock

Can I use the Albert Clock without solving any math?

Yes. Level 0 displays normal time — just the hour and minute as numbers, no equation required. From there, six difficulty settings take you from simple addition and subtraction all the way to combined multiplication and division. The clock adapts to you: start at level 0 and move up whenever it feels right.

Walnut or Oak — which wood should I choose?

Both are oiled solid wood, handcrafted at Zimmermann Uhrengehäuse GmbH in Bavaria. Walnut is darker and richer — it commands a wall and pairs well with leather, brass, and warm-toned interiors. Oak is lighter and more neutral — it integrates into Scandinavian, Japandi, and bright modern settings without demanding attention. If in doubt: Walnut makes a stronger visual statement; Oak fits almost any room.

From what age does the Albert Clock make sense?

At levels 1–2, with simple addition and subtraction, it works well from around age 6 or 7. Boing Boing called it “supposedly made for kids” — but adults consistently report using it as a daily mental sharpener without it ever feeling like exercise. The no-repeat algorithm ensures every equation is uniquely generated, so it stays genuinely unpredictable at any age.

Is the Albert Clock a good gift for someone who doesn’t like math?

Possibly the best one. At level 0 it is simply a beautifully made wooden clock. At level 1 it is low-key and pleasant. The clever part is what happens after a few days: people who “don’t do math” find themselves solving equations instinctively before they have time to object. One user put it perfectly: “It constantly tempts me to master small challenges.” The clock teaches without announcing that it is teaching.

Does the Albert Clock run on batteries?

No. The Albert Clock runs exclusively on mains power. A 3 m black nylon braided cable and a 110V/220V universal power supply are included, together with EU and US plug adapters. The cable gives solid reach, but you will need a socket within range of your chosen wall or shelf position. There is no battery mode.

Can the Albert Clock Wood be used as both a wall clock and a desk clock?

Yes. The clock includes a wall mounting system and also stands freely on a desk or shelf without additional accessories. At 33 × 17 × 5 cm, it fits comfortably on most surfaces without dominating them. The 3 m cable gives you flexibility in either configuration.

How does the difficulty and speed system work?

Six difficulty levels control the complexity of the equation: Level 0 shows normal time; levels 1–2 use addition and subtraction; levels 3–4 add multiplication and division; levels 5–6 combine multiple operations. Separately, six speed levels set how frequently the equation refreshes per minute — slower speeds give more time to solve before the display moves on. Six brightness levels plus an automatic day/night mode complete the control set.

Where is the Albert Clock Wood made?

The oiled wood housing is handcrafted by Zimmermann Uhrengehäuse GmbH, a family-owned workshop in Bavaria, Germany. The electronics and software were developed by Axel Schindlbeck and Fred Mauclere; the company behind the product is MNTNT, based in Paris, founded in 2014. Euronics reviewers noticed it immediately: “The team placed great value on handcraftsmanship — which explains and justifies the price.”
