I’m assuming you mean from Caterpillar factory. I gave my son-in-law one for xmas with a Farmall tractor on one. They cost less than $30.00 new and were sold at farm and hardware stores. They were abundant in the 70ties. John Deere’s were a little more expensive and more collectable. If they are in good shape and still work they might be worth around what they cost new. They could still be made yet. They were kinda a cheap watch.
