When my wife's old carriage clock fell off the mantelpiece and got broken, I scoured the Web looking for a suitable replacement. It turned out to be surprisingly tricky. All I really wanted was a fairly inexpensive clock with a gold look and the essential rotating gold balls under the timepiece itself. Believe it or not, I couldn't find one! Then I came across this product, which fits the bill quite well. It is bigger than our old clock, with a tall (9 inch) rounded cylindrical transparent dome and a relatively high profile. The clock itself is extremely lightweight, obviously all-plastic and presumably driven by a microprocessor; it takes a single battery (AA from memory) and has a single knob on the back to adjust the time. That's it!
The clock looks very good on the mantelpiece. It has kept time reasonably well - gaining about one minute in the month we have had it - and the only peculiarity that you might notice to begin with is that the carriage movement makes a quite audible noise. You might wonder if someone is using machinery down the street, until you come to recognise it; and soon after you will almost certainly stop noticing it altogether.
It would be very nice if the manufacturer had made the clock radio-controlled, so it would always be exactly right. You don't want a clock prominently displayed on your mantelpiece to show the wrong time, nor do you want to spend too much time adjusting it. But at the price, that would perhaps be asking too much at present.
