Drow Science Wastelands Mesh Floor Clock

Something every good post-apocalyptic home should have:
This floor clock was obviously buried under sand and scrap-metal for a considerable time!

It still works nicely and shows the time with high precision.
And as long you keep the nuclear-driven clockwork sealed, it isn't really emiting *that* much radiation ;-)

Factsheet:

Low Lag Clockwork Script with animated clockhands
Only 4 Li
3 meters tall (lower Li, when scaling down)
Lovely detoriated steel case and hollow steel beams ;-)
