Don't know about the current one, but the free watches have been a constant source of amusement/frustration/ridicule ever since I've been on here. I can't remember when I joined, but I've been running for 10 years, and reckon I must have found this pretty soon after that!
I stuffed mine in the back of a draw & covered it with clothes to drown out thew incessant beeping, and total refusal to respond in any vaguely predictable manner to key presses before finally giving up & chucking it in the bin.
In short, buy a decent one. One which can record multiple laps is useful, as is one which has multiple countdown timers. The other thing to look out for is how the watch & strap meet. Most nowadays seem to be moulded all in one, which means you can't just replace the strap if it breaks. I had to ditch a perfectly good "watch" bcause of this.
