My wristwatch recently stopped working, so I decided to buy a poker blinds timer watch as a replacement.
Of course there is no such thing. But I used to compete in marathons and owned such a watch. In marathon training you use an interval timer to pace yourself. A certain number of minutes running, then a certain number of minutes walking. Even if you can't run for five full minutes at a time, with an interval timer you can "train" yourself to run faster, longer.
And what is a poker blinds timer but a series of repeating timed intervals?
For 15 minute blinds you set the the first interval for 14 minutes, and the second interval for one minute. At the first beep you give the one minute warning, then change the blinds on the second beep. For 20 minute blinds you set the first interval for 19 minutes, and the second interval for one minute.
They have a dress watch version as well, but I opted for the black resin strap sports model. It's a decent cheap watch for a poker tournament director. The poker winners can wear the bling.
