While the DGT clocks are all currently a lightweight plastic I have not seen or heard of any issues coming from this type of build. The clocks do seem to last a long time.
The rocker arm is designed such that if one player keeps his side pressed down, by hand, the opponent will have a tough time depressing his side, like a seesaw. I have not heard of any problems with this and no clock breaking in this area either.
The Chronos clocks are built like tanks. And the buttons are independent of each other and also pretty much indestructible. The Chronos clocks feel sturdier with the button response feeling a bit more satisfying when depressed.
I also had a Chronos that had display problems at the turn of the century and sent it in where they fixed it. I donated that clock to our club a few years later and it still works. The problem was in the ribbon from the circuit board to the display. I have not seen any problems like this with the newer ones.
I've been getting back to over the board chess this year after a thirteen year layoff. There has been online chess (not here) in the interval, but it's good to get back to chess on a real board against an opponent I can see. I started going to a local club, and played in tournaments in June and July, sending in my entry for another in September.
Among other things, I treated myself to a bit of extra chess equipment, a DGT 3000 and a Chronos GX touch to go with my old Chronos Blitz button type. I now have enough boards, sets, and clocks to furnish a small club, but that's another story.
One thing I wonder about is the relative durability of the DGT and Chronos. This is something I've often read about, and sometimes heard from other players. The DGT, even the top of the line 3000, certainly does not appear as sturdy as the Chronos, and I could see how the rocker switch would be a problem if your opponent did not take his hand off his side in time. The Chronos appears to be built like a tank. But is there any actual data comparing how they hold up under use, or is it all anecdotes?
I have an older "long" Chronos by the way, that developed display issues back around the turn of the century. That's when I got the Blitz clock. I eventually sent the faulty one back for repair, but it's developed the same problem again. This time I did an improvised repair myself, but I don't know how long it will last. Has anyone had display issues with the DGT?
For now, I think the Chronos Blitz is my favorite, but I used the DGT in my last tournament, and didn't have any issues. I assume that at this point, at least one of my clocks will last as long as I do, and if all the digital ones break, I could see if my old Jerger is still around.
