The chess clock (also called a chess timer or timer) is an essential instrument for any official game. It guarantees fair play by limiting each player’s thinking time. Whether you’re playing a 3-minute blitz or a 2-hour classical game, understanding time controls and choosing the right clock will make all the difference to your play.
Why use a chess clock?
Without a time limit, a player in a losing position could think indefinitely. The clock solves this problem by giving each player an identical time allowance. When a player makes their move, they press their clock button, which stops their own clock and starts their opponent’s. A player who runs out of time loses the game on time.
Official time controls
| Time control | Time per player | Character | Use |
|---|---|---|---|
| Bullet | 1 to 2 minutes | Ultra-fast, pure reflexes | Mainly online |
| Blitz | 3 to 5 minutes | Fast, intuitive | Clubs, online, tournaments |
| Rapid | 15 to 60 minutes | Moderate thinking | FIDE rapid tournaments |
| Classical | 60 to 120+ minutes | In-depth thinking | Official championships |
The increment: a safeguard against time trouble
The increment (or addition) is a time bonus added after each move played. For example, in a “3+2” time control, each player starts with 3 minutes and receives an extra 2 seconds after every move. This system, introduced by Bobby Fischer (hence the name “Fischer increment”), stops games being decided purely by speed of execution towards the end.
Digital vs analogue clocks
Digital clock
- Precise second-by-second display
- Automatic increment handling
- Multiple programmable time controls
- Essential for modern tournaments
- Budget: €25 to €80
Analogue clock
- Classic, elegant look
- No batteries needed (mechanical)

- Suited to friendly, decorative play only
- Budget: €40 to €150
FIDE approval: which models should you choose?
For official tournaments, the clock must be FIDE-approved. The benchmark models are the DGT 2010 (the most widely used in international tournaments), the DGT 3000 (larger screen) and the Leap KK9908 (affordable option). These clocks all handle Fischer and Bronstein time controls, as well as multi-period controls.
