I think it’s a good thing they have an endowment to give the site more financial security, but… how big does it need to be before they stop the begging advertisements? They’ve already far outpaced the goal they set in 2016.
Higher beat quartz watches do exist, like Bulova’s Precisionist watches (which I believe do beat 16 times per second like you mention).
My understanding is that they are not more common because moving the hands more frequently like this uses battery a lot faster, so the watches either need to be bigger for more battery or require more frequent battery changes.
Do you think it’s not newsworthy if a manufacturer sells drives with a history of failures, releases a firmware update they claim will fix the issue, sends a replacement drive that also fails, and continues to sell the drives at a deep discount?
