Best Chess Clock (2026): Delay, Increment and Why It Matters

A chess clock changes the game more than any other piece of equipment, because it turns thinking time into a resource you can run out of. The part beginners rarely have explained is that not all timed chess is the same: delay and increment are different rules that produce very different endgames, and the clock you buy determines which ones you can play.

The 30-second verdict
  • Increment adds time after every move and accumulates. Delay waits before your clock starts, and does not accumulate.
  • Increment is what almost all modern online and tournament chess uses. Make sure your clock does it.
  • Digital over analogue. An analogue clock cannot do delay or increment at all.
  • If you play at a club, buy what the club uses — usually DGT. Familiar buttons matter under time pressure.
  • Set-up matters more than features. A clock you cannot configure quickly is a clock you leave in a drawer.

Delay and increment, which are not the same thing

Both exist to stop games being decided by who can move a mouse or a hand fastest in a lost position. They do it differently.

Increment (also called Fischer) adds a fixed amount to your clock after every move you make, and it accumulates. In a 5+3 game you start with five minutes and gain three seconds each move — so if you move quickly you can finish with more time than you started. This is what online chess uses almost universally, and what most modern tournaments use.

Delay (Bronstein or simple delay) waits a few seconds before your clock begins counting down. Move within the delay and you lose nothing, but you never gain time. In a 5 d3 game you always have three free seconds per move and your five minutes only shrinks.

The practical difference shows up in endgames. With increment you can always earn enough time to play accurately, so games are decided by chess. With delay, a long endgame still grinds your main time away.

If you are buying one clock, buy one that does increment properly.

Why not analogue

Analogue clocks — the two-dial ones with the little flag that falls — are handsome and are still the picture most people have of a chess clock. They also cannot do delay or increment, because both require the clock to count in a way mechanical movements cannot.

That rules them out of most modern play. They are also less precise, they need winding, and the flag makes the final seconds a matter of interpretation.

Buy analogue if you want the object. Buy digital if you want to play the formats other people are playing.

LEAP Chess Clock Digital Timer Advanced for Game and Chess Timer with…Best for home play

LEAP Chess Clock Digital Timer Advanced for Game and Chess Timer with…

$26
TypeDigitalModesDelay, increment, countdownBest forHome and casual

A capable digital clock at a price that makes buying one an easy decision, and it genuinely does the modes that matter — both delay and increment, plus straight countdown. For playing at home, teaching a child, or running a casual game with friends, there is nothing here you will miss. The compromises are physical rather than functional: the plastic case is light enough that it slides on a table, and the buttons are less satisfying than the tournament clocks, which you notice when slapping them at speed in a blitz game. Menu navigation is also fiddlier, so expect to keep the manual for the first few sessions. For a first clock, this is the right amount to spend.

What's good

  • Does delay and increment properly
  • Very cheap for a full-feature digital clock
  • Clear display
  • Fine for home and teaching

What's not

  • Light plastic case slides on the table
  • Buttons feel cheap under fast play
  • Fiddly to configure from memory
  • Not what clubs use

DGT 1001 Digital Chess ClockBest for most people

DGT 1001 Digital Chess Clock

$40
TypeDigitalModesCommon tournament presetsBest forHome and club

DGT is the brand chess actually runs on, and this is their straightforward one. The case is solid enough to stay put when a button is hit hard, the buttons themselves are large and positive so you always know your move registered, and the display is readable across a table. Configuration is deliberately simple — a small set of preset modes rather than a deep menu — which is exactly right if you play a handful of time controls and do not want to relearn a menu each time. The trade-off is that it does not carry the full tournament mode list of the 3000. If you play at home and occasionally at a club, this is the clock to buy.

What's good

  • Solid case, stays put when slapped
  • Large positive buttons
  • The brand clubs and tournaments use
  • Simple to set without the manual

What's not

  • Fewer preset modes than the 3000
  • No Bronstein-style options on some settings
  • Plainer display than the flagship
  • Costs more than the function gap suggests

DGT 3000 Digital Chess ClockBest for club and tournament

DGT 3000 Digital Chess Clock

$80
TypeDigitalModesFull tournament, multi-stageBest forRated and club play

The clock you will see on the boards at serious events, and the reason to buy it is compatibility rather than features. It carries the full set of official time controls as presets, including the multi-stage ones that longer tournaments use — where the format changes after a set number of moves, which cheaper clocks simply cannot express. The display shows move count and the current stage, so both players can see where they are in a long game. It is more clock than a home player needs, and setting it up rewards reading the manual once properly. Buy it if you play rated chess, or if your club uses them and you would rather practise on the buttons you will compete on.

What's good

  • Full official tournament time controls
  • Handles multi-stage formats cheaper clocks cannot
  • Move counter and stage display
  • What you will meet at events

What's not

  • Twice the price of the 1001
  • Deep menu — read the manual once
  • Overkill for home play
  • Larger footprint

Press the clock with the hand you moved with

One hand for both the piece and the clock — it is a rule in tournament play, and it is a good habit anywhere. Using two hands lets you move and press simultaneously, which is how people accidentally claim time they did not use, and it is the most common thing beginners get pulled up on at their first club night.

What time control to actually play

For learning, longer is better. 15+10 or 10+5 gives you enough time to calculate and to notice why a move failed, which is where improvement comes from.

Blitz (3+2 or 5+0) is enormous fun and teaches pattern recognition and nerve, but it does not teach calculation — you are running on instinct by design.

Bullet (1+0) is a different game wearing chess as a costume.

A reasonable rule while learning: play mostly at 10 minutes or more, and treat blitz as dessert rather than dinner.

Before you buy

Check it does increment, not just delay. That is what modern chess uses.

Digital, unless you want an analogue clock as an object.

Playing at a club? Buy what they use — the buttons matter under pressure.

Try setting it up in the shop or from the manual before committing.

Heavier is better. Light clocks slide when you slap them.

Chess clock questions

What is the difference between delay and increment?

Increment adds a fixed amount to your clock after each move and it accumulates, so moving quickly can leave you with more time than you started. Delay waits a few seconds before your clock starts counting, so you never lose time for a fast move but you never gain any either. Increment is what almost all modern online and tournament chess uses.

Do I need a digital chess clock?

Yes, for practical purposes. Analogue clocks cannot do delay or increment, because both require counting in ways a mechanical movement cannot manage — which rules them out of most modern time controls. Analogue clocks are lovely objects, but buy one for that reason rather than for playing.

What time control should a beginner play?

Something with real thinking time — 15+10 or 10+5. You improve by calculating and by having time to see why a move failed, and blitz gives you neither. Fast chess is excellent for pattern recognition and nerve, but treat it as dessert rather than the main meal while you are learning.

Which chess clock do tournaments use?

DGT clocks, overwhelmingly. If you plan to play at a club or in rated events, buying the same brand means the buttons and menus are familiar when it matters — under time pressure is a bad moment to be learning an unfamiliar interface. The DGT 3000 carries the full set of official multi-stage time controls.
Bottom line

Buy a digital clock that does increment. The DGT 1001 is the one for most people — solid, simple to set, and the brand your club will already be using. The LEAP is a genuinely capable clock for home and teaching at a third of the price. The DGT 3000 is worth it if you play rated chess and need the full multi-stage tournament controls. And press the clock with the hand you moved with.

Best Beginner Chess Sets (2026): 3 Real Picks

A tournament-style set is the right first chess set: standard-size Staunton pieces, weighted so they don't tip, on a board with 2.25 inch squares. Skip the decorative themed sets for now. The one real decision is vinyl (cheap, portable, what clubs actually use) versus wood (nicer to own, costs more). Everything below is a set people genuinely buy and play on.

Best Go Sets for Beginners (2026)

A Go set is just a board, a bowl of black stones, and a bowl of white, but the details make a real difference when you are learning. Magnetic stones that do not slide, a full 19x19 grid, and a board that lies flat all make the game easier to focus on. Here are three complete sets, from a travel board to a bamboo one.

Best Gaming Headset (2026): Wired, Wireless and What Actually Matters

Most gaming headset marketing is about surround sound. Most actual complaints are about weight, clamp pressure and a microphone that makes you sound like a drive-through. The specifications that decide whether you still like a headset after six months are comfort and the mic, and neither appears in the headline.

Best Gaming Monitor for Beginners (2026): 3 Picks from 1080p to 240Hz

Your first proper gaming monitor is one of the biggest upgrades you can make, and it comes down to three numbers: resolution (how sharp), refresh rate (how smooth), and response time (how quick). The one you feel most is refresh rate. Going from an ordinary 60Hz screen to 144Hz or more makes everything look noticeably smoother, and it is the whole reason to buy a gaming monitor. Here are three good ones, from an affordable 1080p screen to get you into high-refresh gaming, up to a fast 240Hz do-it-all display.

Best Cooperative Board Games (2026): Playing With the Table, Not Against It

Cooperative games are the easiest way into board games with people who do not think they like board games, because nobody gets knocked out and nobody has to be the one who ruins a friendship over a trade. They also have one specific failure mode that no box warns you about: the loudest player quietly starts telling everyone else what to do.

Best Gateway Board Games for Beginners (2026): 3 to Start With

Here is the honest truth: you do not need all three of these, any one of them is enough to get a good game night going. Gateway games are the ones built to win over people who think they do not like board games, the friends and family who groan at the word Monopoly. They teach in about five minutes, finish in under an hour, and leave everyone wanting another round. What they are not is Monopoly, Risk, or Trivial Pursuit, the long, luck-heavy, knock-you-out games most of us grew up quietly dreading. This guide is three different games at rising price and complexity, not three versions of one thing. Start with an easy, gorgeous crowd-pleaser, move to the classic that got a generation into the hobby, and step up to a richer game once your table is hooked. Buy one, get it played a few times, and add another only when your group is asking for more. Here are three good ones, and honest advice on where to start.
