Clock nuts. Acorn clocks and their variations.

One doesn’t see this gathering very often. The only example missing is the shelf form that does not have side arms.
All seven of these examples are currently in collections.
The top three are wall versions. The one in the center features a geometrically themed tablet.
The shelf clock located in the front and center is very unusual in that it has sidearms.
The shelf model behind it features a very unusual case style. Note the difference in the dial and head shape. This also translates to a different molding below the dial and a more complex two part sidearm.
