Best Chess Clocks 2026: DGT North American vs LEAP vs Chess Armory

The clock to buy for rated play in the United States is the DGT North American. It runs a true US delay countdown the way the US Chess rulebook prefers, it also does Bronstein and Fischer increment for FIDE-style controls, every tournament director has set one a hundred times, and it goes years on two AA batteries. If you play club blitz and casual games, a LEAP digital clock covers delay and increment for roughly a third of the price. The Chess Armory digital clock sits in the same budget tier and is a sensible second clock or scholastic loaner. Below: what "delay" and "increment" actually mean on each box, what the rules say about whose clock gets used when two players disagree, and the button, display, and battery details the spec sheets leave out.

The short version

Prices on the two budget clocks move constantly, so treat those as ballparks rather than quotes. The DGT's price is steadier because it is sold through the same handful of chess retailers year after year.

Delay, Bronstein, and Fischer: what the modes actually do

Three timing modes cover nearly every event you will enter, and the words on the packaging are used loosely enough that it is worth pinning them down.

Fischer increment (marketed as "bonus" on budget clocks) adds a fixed number of seconds to your remaining time after every move you complete. Move quickly and your time grows; a player with 30 seconds of increment can bank several minutes across a long technical endgame. This is what FIDE uses for its standard control (90 minutes for 40 moves, 30 more for the rest of the game, with 30 seconds added from move one) and what a growing share of US Chess events use in place of delay at slower controls.

US delay (sometimes "simple delay") makes the clock wait a fixed number of seconds before your main time starts counting down on each move. Use less than the delay and you lose nothing; use more and only the excess comes off. Your time can never go up. US Chess events have used a 5-second delay as the default for roughly two decades, and the rulebook's stated preference for a clock that visibly counts the delay is the single strongest argument for buying a clock designed for the US market.

Bronstein delay produces exactly the same remaining time as US delay but displays it differently: the main time starts ticking immediately, and the delay you used, up to the maximum, is added back when you press the button. Mathematically the two are identical. Visually, Bronstein looks like your clock is bleeding during the delay, which unsettles some players and confuses some directors. A European clock that offers only Bronstein will be accepted at a US event, but if you have a choice, a true US-delay display avoids the conversation.

A quick check for any clock: set a 5-second delay with one minute of main time and press the button. If the minute sits still for five seconds before moving, that is US delay. If it starts dropping immediately and jumps back up after the press, that is Bronstein. If it starts dropping and never comes back, the "delay" mode is mislabelled and you should not rely on it at a rated event.

What the rulebook says about whose clock gets used

US Chess does not certify clocks. There is no seal on the DGT box, and there is no banned list beyond common sense. What the rulebook's equipment chapter does is establish an order of preference. In outline: when the announced time control uses delay or increment, a properly set clock with that capability is standard equipment and takes precedence over a clock without it. If both players bring a capable clock, Black's preference generally carries, subject to the director's judgment about which clock better suits the event. An analog clock, once the default, is now the fallback used when nobody has anything better.

Two practical consequences follow. First, any of the three clocks here is legal for rated play. Second, the director's familiarity is a real feature. A DGT that a TD can set blind in fifteen seconds is worth more at the start of round one, with thirty boards waiting and the announcement reading 40/90, SD/30, d5, than a budget clock nobody in the room has seen. If you plan to bring a LEAP or a Chess Armory to a rated event, pack the manual. The menu sequences are not intuitive, and the one time you need them will be under pressure.

DGT North American: the tournament default

The North American was built by DGT for US time controls, and its whole reason to exist is that the earlier DGT 2010 handled Bronstein but not the US-delay display American directors wanted. It does US delay, Bronstein, Fischer, plain countdown, and multi-period programs such as 40 moves in 90 minutes followed by sudden death, with the second period triggered by the move counter. That move counter is a genuine tournament feature: after a time-control scramble, both players can check whether move 40 was reached, and the clock's count is a starting point (not the final word, which is the scoresheet) when they disagree.

The buttons are two large, flat plates on top of the case with a short, firm travel and a positive click. That matters more than it sounds. In a blitz tiebreak, a button with a mushy or ambiguous press produces disputes about whether the clock was pressed at all. The case is a low wedge, wider than the budget clocks, and it sits flat on a vinyl board without rocking.

Its drawbacks are real but minor. The display only switches to a minutes-and-seconds view once a side drops under 20 minutes, so in a 90-minute first period you see hours and minutes, which bothers players raised on phone timers. The setup procedure, which uses a small setting button and a sequence of flashing fields, is fast once learned and baffling the first time. And it costs two to three times what the budget clocks do. For a player entering rated events more than a couple of times a year, that premium buys the clock the rest of the room already knows.

LEAP: the club and blitz workhorse

The LEAP is the clock you see in bulk at scholastic clubs and casual blitz sessions, and for that job it is hard to argue with. The display is large and shows seconds at all times, the two top buttons are broad and easy to hit at speed, and the mode list covers straight countdown, a delay mode, a Fischer-style bonus mode, and multi-period controls. It is light, which cuts both ways: easy to carry, easy to shove across the table during a scramble.

The trade-offs cluster around precision and longevity. The buttons are lighter and noisier than the DGT's, with longer travel, so a player who taps rather than presses will occasionally fail to register a move. The setup menu leans on a numbered mode system and a tiny manual, and the delay behavior should be verified with the one-minute test above before you trust it. Build quality is adequate rather than robust; the battery door and the button surrounds are where these clocks age. None of that keeps it out of a rated event. It does mean that if it is your only clock, you should know its menus cold before round one.

Chess Armory: the budget backup

The Chess Armory clock is functionally a close cousin of the LEAP: countdown, delay, bonus, a large always-on-seconds display, two top buttons, and a low price. The differences are cosmetic and in the details of the menu. It is a reasonable second clock for a household with two kids in scholastic events, a spare for a club that loans equipment, or a first clock for someone who wants to learn time controls without a large purchase. As a primary clock for adult rated play it is fine but unremarkable, and the same advice applies: verify the delay behavior, learn the menus, keep the manual in the bag.

If you are choosing between the LEAP and the Chess Armory on a given day, the honest answer is that the price on that day should decide it. They occupy the same tier and do the same job.

Button feel, display, and what spec sheets don't say

Three details separate clocks in practice that never appear in a feature list.

Button travel and click. A tournament game involves a few hundred button presses, many made without looking. A clean, short travel with audible confirmation reduces both missed presses and the "did you hit it?" exchange. The DGT is the standard here; the budget clocks are usable.

Legibility from an angle. You read a clock from a seated position, off to one side, often under fluorescent light. Big, high-contrast digits are worth more than any extra mode. All three are acceptable; the budget clocks' larger digits partly compensate for their other shortcomings.

Flag behavior. When a side hits zero, a good clock shows a flag symbol and holds it, so a loss on time can be verified after the fact when the director is called over. All three flag; the DGT holds it until the clock is reset, which is what a director wants to see.

Batteries and failure modes

A dead clock at the board is an immediate problem, because the rulebook expects a working clock and the director may not have a spare. DGT rates the North American for years of use on a pair of AA cells, and a club clock rarely needs a change between one annual battery sweep and the next. The budget clocks draw more from their always-on displays and, in the Chess Armory's case, use smaller cells, so plan on replacing them more often and carry spares in the same bag as the clock. Whatever you own, the pre-tournament checklist is short: fresh batteries, the announced control programmed and tested, the manual packed.

Who should buy which

• You play rated US Chess events, even a few a year: the DGT North American. It is the clock the room knows, its delay display is what the rulebook prefers, and it will outlast several budget clocks.
• You run a club, teach, or need six clocks for a scholastic team: LEAP or Chess Armory in quantity, with one DGT for the top board. Price on the day decides which budget clock.
• You play FIDE-rated events, want seconds always visible, or want five custom programs stored: step up to the DGT 3000, which this site compares with the North American separately. It costs more, and most club players will never touch its extra modes.
• You want a clock still in service in fifteen years: a Chronos, if you can find one at a price you can stomach. It is not covered here because availability and pricing are inconsistent, not because it is bad.
