There is a free and open source app called SelfControl for macOS. It allows one to block access to any site one adds to the list in the app for the amount of time the user chooses. Attempt to use multiple browsers, restarting one's machine, deleting the app, etc. won't get around the block either. It's been super helpful for me, so I thought I'd just throw it out there. https://selfcontrolapp.com. - Source: Hacker News / 6 months ago

It is SelfControl. It is open-source and free. You select the website you want to block and the time. The moment you click the button no matter what you do, you can forget about accessing those websites until the time is over; there is no cancel button. Restarted mac won't work, you can delete the app no luck. Source: 7 months ago

When I was learning how to sprint (300m intervals) I used Moov and it was amazing. Also tracks cadence and does the voice over coaching. Tells me to speed up, swing my arms more, etc. Can't recommend it enough, and it's probably even better since mine was an earlier version. https://welcome.moov.cc/. Source: over 1 year ago

Not a watch, but I still like the moov now. It's clearly not being developed anymore but is a bargain now, assuming the app continues to work when the company inevitably goes away.
