London's Backes & Strauss as well as being the oldest diamond company in the world, have branched out into some eye-catching diamond watches. Maybe a bit too much for the school run, these watches are stunners. Backes and Strauss was founded way back in 1789 when Regency London was taking form. The house's watch collections are all named for famous London squares and the Berkeley Collection is inspired by Berkeley Square of course, famous for its looming plane trees, among the oldest in London, that were planted in 1789, the same year Backes & Strauss was founded. Having all that diamond expertise and diamond cutters to hand means that these watches shimmer with the pick of the crop of Backes & Strauss' diamonds. I love the fact that the diamond in the crown is set pointy-side down so that you don't get scratched. Details like these take the idea of diamond watches to a new sphere. And for those with more restrained tastes, there are some diamond-free dials in the collection.
