Probably not exactly on topic, but the nearest thing without starting a new thread.
As I have written elsewhere, my stepfather inspired in me a love of clocks, watches, barographs and timepieces of all sorts and I have a fairly wide and eclectic collection, some bought but most handed down through the family. I keep them for love but I thought that the combination of quality, rarity value and favourable CGT treatment meant that they had an investment case too. I've had a bit of a rude awakening. Whilst high end watches still seem to be in demand, I have only just discovered that the market for antique clocks has fallen off a cliff. At the top of my collection pyramid is a bracket clock made by a good maker in 1675. Browsing auction catalogues, I am now seeing equivalents at around one third of values a few years ago. Reading articles, it seems that this is an extension of younger generations' disregard for 'brown furniture', compounded by the fact that many of them don't use analogue timepieces at all. (My 36yo has never worn the Rolex given to him on his 18th birthday. "I use my phone"). Sad. I shall continue to enjoy mine but when the time comes I suppose I'll just have to leave them to a museum.
