Lorenz "Olio Fiat" Electronic Diapason Wall Clock — Genuine Jeco Movement

A square-cased wall clock by Lorenz, the well-known Italian clock manufacturer, produced for Fiat's "Olio Fiat" motor oil brand and featuring their logo on a yellow tile-style graphic on the lower dial. The black face displays bold white Arabic numerals, a full minute track, white hour and minute hands, and a red seconds hand, with "Lorenz — Electronic Diapason Clock" marked beneath the 12 o'clock position.

The reverse of the case confirms genuine period electronic tuning-fork (Diapason) movement technology, stamped "Jeco Co., Ltd, Japan" with visible patent numbers — Jeco was a well-established Japanese manufacturer that supplied Diapason movements to European clock brands including Lorenz during the transitional years before quartz movements became standard. An original Italian-language service instruction sticker is also present inside the case, confirming the clock's original Italian market. Together, these details place the clock's production in the late 1960s to mid-1970s.
