Avalon Oversized LED Digital Wall/Desk Clock - 2 pack

Is there a published specification on how much this clock will drift over time?

I actually bought one of these off Amazon a few months ago, to replace a 30-year-old Radio Shack big clock, and it’s a worthy successor.

Not the best plastics, and the desk stand is just stupid. But it’s dead-on accurate, and readable at a glance from pretty much anywhere in any lighting condition.

$54.99 for one of these over on Amazon - if I read this correctly lol
