Metamec electric wall clock made in england

Beautiful metamec brand wall clock made in england from the 1960s-70s. Colors black and gold very chic and trendy. Operation by conventional 220v electrical connection. It is functional: test for more than 24 hours; the movement of the second hand is fluid (without jerks and without ticking therefore). Curved glass in excellent condition. Curiously the original sticker is always placed on the glass: either this clock was not used, or the former owner used it without removing the sticker... There is a tarnishing of the golden outer border but it is rather the golden one that has undergone a change in hue by age: no splinters of the golden layer. Traces of normal use at the back.
