Copper Gear Big Number Clock

A gear train showing through an openwork ring

A cast ring with large numerals pierced through it, and inside that a second ring showing a stack of gear wheels of different sizes, all moulded in relief. The whole piece carries an aged metallic finish, darker in the recesses and polished on the raised edges. The hands are long and openwork.

Everything between the numerals is cut away, so the wall shows through the outer ring while the gear cluster stays solid in the middle. That contrast is what gives the clock its depth.

One version. The pictures show it in a copper finish and in a verdigris green.
