Watchmaker Rebecca Struthers shares her passion for the art and science of horology. She warns that this traditional skill and its allied trades to make and restore watches, are endangered in Britain unless we make it easier for the next generation to be trained in them.

"When well-made objects are cared for, it's a cycle of relationships that can span centuries. The oldest family watch I've worked on was five generations and 250 years old. When working on an object that symbolises the passing of time itself, I'm acutely aware of the fact that I've become a moment in the history of this watch, a moment in time for an object that was made centuries before my birth and will live on centuries after I'm gone."
