Which chess clock is good for tournaments?

I've decided to buy a chess clock for tournament purpose. Budget is around ₹2000 to ₹5000.

Which clock do you suggest? 

Would DGT be good?

The DGT NA is easy to set.  Could you translate your budget to Euros or US Dollars?

I bought the blue DGT "North American" 10 years ago for $ 40. The display has gotten scratched from use, but it continues to work well. The rocker switch remains almost silent. 

DGT is usually a safe bet.  Are you playing FIDE or national tournaments?  If it is national tournaments, you should see what the organization will accept fora clock. 

At that price range, the DGT 3000 would be the best option, in my opinion.

U know that U can just download something on your phone and its called "chess clock"?

It works the same way as the chess clock, but it is free.

So you can practice with it...

one tip for you:u need to tap the clock with the hand you're playing with.

^^ He said he wants it for tournaments. Think about it.

$26.31 to $65.78

It's FIDE tournament

Yeah for practice i can use app. But for tournament, we can't use mobile.

Yeah, idk what to choose. DGT 2010 or DGT 3000.

Other than the risk of a cell phone ringing (often resulting in loss of time or loss of game), the risk of a text being displayed (risking loss of game), many organizers requiring phones to be turned off (possibly also requiring them to be in bags and not on a person) and some organizers banning them from the playing area (having one might result in loss of game), what problems do you see?

They're basically the same thing.  The 3000 has a larger display, more built in modes, and can connect to a smart board.   But it is up to you if those things are worth the higher price tag. 

I was wrong. Apart from losing the game when you pull your phone out, it's an excellent choice!

DGT is still the king for officially rated tournaments. Other digital physical chess clocks like Chronos and ZMF may work, but you'll have to check with the tournament organizers in advance for their accepted choices.

I've had the same ZMF clock for 6 years and I've never had a problem with it. I feel they're higher quality and more durable than DGT. 

DGT 2010 or DGT 3000.

Such apps exist but don't expect arbiters to allow them.  The only time I allowed them was for a non-rated casual scholastic G/20 (no games started with a clock) where I'd accidentally left my clock at home and needed to put one on the only game to go more than twenty minutes (I used my own phone to ensure that the phone did not have any chess playing app).
