If you landed here looking for a chess clock, I’ll try to help without the marketing. Almost every European tournament now runs on electronic clocks — because they can add time after every move. The other kind, the mechanical one, doesn’t do that. It also doesn’t need a battery, and you never forget how to set it.

Why a clock at all
A chess clock is not a kitchen timer. It splits one game into two clocks, so each player spends only their own time. That single idea is what makes a game fair under pressure, and what turns a friendly session into something with a finish.
For a child it is also a new piece of the game. It can be exciting — and sometimes stressful — because they have to remember it is there. That is a reason to introduce it early, gently, not as a punishment. A small aside: the same dual timer works for Scrabble, shogi, go, draughts and a few other turn-based games. One clock in the house covers more than chess.
At home it does a second job: it sets the atmosphere. A wooden mechanical clock ticking next to a board is a different evening from a silent plastic brick. Both keep honest time. They are not the same object.
The two kinds
There are only two families that matter in practice:
- Electronic (digital) — LCD or LED, programmed time controls, increment and delay, sometimes a move counter and a second time period after move 40. This is what you will see on almost every European tournament table in 2026.
- Mechanical (analog) — a spring, two dials, and a falling flag. Wind it, set it, play. No increment. No batteries. The ticking is part of the game.
If you play rated events, you already know which one the organiser will put on the table. If you are buying for a living room, a club night, or a shelf that also has to look like furniture, the answer is less obvious — and that is the actual decision this guide is for.
Electronic clocks — what they actually do
About 99% of tournaments played in Europe now run on electronic clocks. The reason is not fashion. It is a function mechanical clocks simply do not have: adding time after every move. Two seconds in blitz. Thirty seconds in a long game. A second time control after 40 moves. A delay before the clock starts counting. All of that lives in firmware you program once and then trust.
Serious players almost always own one of these, because the older mechanical tournament clocks are no longer how World Championship matches are played. If you want to practise the same rhythm you will meet on a Saturday morning, you practise on digital.
What the electronics actually add
- Increment (Fischer) and delay (Bronstein / US delay).
- Move counting, and extra time after a set number of moves.
- Exact presets to the second.
- On some models, a cable to an electronic board for broadcasting.
Bought privately, most of these clocks will spend their lives on friendly games and fast sessions. Tournament organisers already supply clocks. A FIDE endorsement is a nice extra, not a requirement for the kitchen table. The laws of how the thing behaves — press, flag, pause — are essentially the same from one brand to the next.
Who actually makes them
Two names dominate Europe: DGT in the Netherlands, and LEAP in China (you will also see it written Leap). DGT is the one you will see at championship-level events, and the one that talks to DGT electronic boards. LEAP is the honest budget workhorse — widely used in clubs and scholastic events, with at least one FIDE-endorsed model (the KK9908). For home play, both do the same job.
The quality ancestor a lot of players still remember is Saitek. It was expensive for its time, which is why it never became the mass tournament standard. The ones that survived are now twenty-plus years old and, in my experience, still run. That is not a claim I would make about every plastic digital clock on the market today.
How long they last
Used as chess clocks, they are surprisingly tough. On professional events they get hammered in blitz — slapped rather than pressed — and they keep going. Play itself is not usually what kills them.
Leaving them unused, or simply getting old, is more often the problem. Folding models have had hinge ribbons tear. Battery baskets have cracked after a few years. As with most modern electronics, I would not buy one expecting it to outlive you. The big brands refresh the casing and the menu every few years; a handful of presets still cover almost everything people actually play.
Mechanical clocks — the ones I keep
This is the category I actually like. Not because it is more precise — it isn’t — but because of what it does not ask of you.
- No battery, so nothing to leak in a drawer.
- You always remember how to set it. With a digital clock you read the manual, memorise which program code is which time control, and then, at a certain age, the print on the back is too small to read.
- Simplicity, durability, the look of wood or bakelite, and the ticking.
That last point about batteries still surprises people. Some years ago two of my students brought me an old mechanical chess clock and asked me to change the battery — it had “stopped working.” They had never met an object that ran without one. I wound it. It ticked. The look on their faces was the whole lesson.
Clocks were metal first, then wood and bakelite, and later plastic. My first one was a Soviet Jantar — white plastic, nothing glamorous. You can still find BHB clocks made in Łódź by Mera Poltik, sold under names like Hetman. Choosing a mechanical clock is mostly choosing an aesthetic, because it is not only a timer. It is an object in the room, and sometimes a souvenir.
There are not many things I have owned for thirty years. When I left my parents’ house, the chess set came with me — and so did the clock.
The honest downsides sit in one sentence: it does not add time after a move, and it is not precise to the second the way a digital display is. For a long tournament game with a 30-second increment, that is disqualifying. For a club evening, a home game, or a board that stays out on a table, it is not.
Electronic vs mechanical, side by side
| Feature | Electronic | Mechanical |
|---|---|---|
| Time controls | Increment, delay, multiple periods | Straight time only — no increment |
| Precision | To the second; exact presets | Good enough to play; less granular |
| How you set it | Menus and program codes | Wind, set the hands, play |
| Power | Batteries or a charger | A spring |
| Repair | Often cheaper to replace than to fix | A watchmaker can usually service it |
| Lifespan I would bet on | Years of hard use; not decades | Decades, if it is serviced |
| Sound | Beeps, or silence | The tick, and the flag |
| What it is, besides a timer | A tool | A tool, and often an object you keep |
| Where it belongs | Tournaments, blitz, training with increment | Home, club, display, collecting |
Plenty of players own both: digital for blitz and tournament prep, mechanical for the games that happen in the house. That is not indecision. It is two jobs.
Brands worth knowing
On the digital side, start with DGT and LEAP and stop there unless you have a specific reason not to. On the mechanical side, a few names actually mean something.
UMF Ruhla / Gardé (GDR)
The last great mechanical tournament clock. Four generations, from the early striped wooden cases of the 1960s (Leipzig Olympiad, 1960) through to the wider late model of the 1980s–90s. A workhorse in its day, and now the clock collectors recognise on sight. Full generations, sizes and tells: UMF Ruhla / Gardé — the guide.
Koopman (Netherlands)
Clear dials, a robust case, and a flag mechanism (Patent 65843) that still reads cleanly. Practical in its day; collectible now, without becoming jewellery. More on the lineage: Koopman mechanical clocks.
HAU / HAC (Germany)
Early twentieth-century wooden clocks from Hamburgisch-Amerikanische Uhrenfabrik — HAC in English. One we restored carried a Danish club plaque from 1930–31 and no red flags, which is unusual for the type. The object was a document as much as a timer: the 100-year-old HAU chess clock.
Jantar, BHB, Hetman
Not luxury. Not rare in the auction-house sense. These are the plastic mechanical clocks a generation of club players actually grew up with — Soviet Jantar, BHB, and the Polish Mera Poltik / Hetman line from Łódź. They are getting harder to find in honest working order, which is usually how collecting starts: not with a manifesto, but with the clock you remember.
How to choose one
Start with the job, not the brand.
- If you need increment — tournament practice, modern blitz, anything with “+2” or “+30” in the time control — buy electronic. DGT if you want the clock you will see at serious events; LEAP if you want the same functions without paying for the badge.
- If the clock will live in the house — on a board that stays out, next to a wooden set, as something you still know how to set in ten years — look at mechanical. Wood if it has to sit with furniture; a well-kept plastic classic if you want the club feel without the collector price.
- Condition, on a mechanical clock — original dials and hands, a flag that actually falls, a movement that sounds even, and some record of service. Pretty and stopped is a sculpture, not a clock.
- FIDE certification — relevant if you are an organiser, or you insist on bringing your own clock to a rated event. For a private purchase, treat it as a quality signal, not a requirement.
- Readability and feel — contrast on the dial or the display, the shape of the hands or digits, how the button feels when you are short of time. You will notice this more than the spec sheet.
Why we restore vintage clocks
At ChessboArt we treat these as functional objects, not as props. A movement that still times a game is worth more than a polished case with a dead heart. We service the mechanism, keep original character where it survives, and put the clock back on a board — and on a living-room table — rather than under glass.
The longer version of how we work, and what we will and will not do to a case, is here: Why we restore vintage chess clocks.
A small honesty: restoring a clock takes time, and not every case is worth opening. If you have a specific model in mind, it is better to ask than to assume we have three of them on the shelf.
FAQ
Do I need a FIDE-certified clock for home play?
No. Organisers provide clocks at rated events. A FIDE endorsement is useful if you will bring your own clock to a tournament, or if you want the same model you will see on a championship table. For friendly games it is optional.
Are mechanical clocks good for everyday play?
Yes — if they are in good condition and have been serviced. Wind them regularly and treat the buttons as buttons, not as punchbags. They will not run a 10+2 blitz the way a digital clock will, and they are not meant to.
Can I use a mechanical clock in an official tournament?
Modern events almost always require digital controls with increment or delay. Mechanical clocks belong in clubs, casual games, analysis, and vintage-themed events — not in a FIDE-rated open with a 30-second increment.
Why don’t mechanical clocks have increment?
Increment is a digital idea: add a fixed number of seconds after every move. A spring-driven movement with a falling flag cannot do that. That single missing function is why electronic clocks took over tournament play, not because wood went out of fashion.
How long do electronic chess clocks last?
They survive a surprising amount of blitz abuse. What ages them is more often unused years, tired hinges on folding models, and cracked battery compartments. I would plan in years of hard use, not in decades. A well-built exception like an old Saitek can last longer — that is the exception, not the current rule.
What is the difference between DGT and LEAP?
DGT (Netherlands) is the clock you will see at championship-level events and the one that connects to DGT electronic boards. LEAP (China; also written Leap) is the widely used budget alternative, with at least one FIDE-endorsed model. For home and club play the functions overlap; you are mostly paying for build, support, and which table the clock already sits on.
What do HAU and HAC stand for?
HAU is Hamburgisch-Amerikanische Uhrenfabrik. HAC is the same factory in English: Hamburg American Clock Company. Early twentieth-century wooden chess clocks, now rare in original working order.
Can I use a chess clock for other games?
Yes. The same dual timer is routinely used for Scrabble, shogi, go, draughts, and similar turn-based games. If the household plays more than chess, one clock is enough.
