Surrounded by dazzling diamonds and gemstones is a digital wristwatch, on a frayed woven rope strap. With its simple LCD display in a yellow gold case, the watch looks a little out of place amid the delicate, glittering finery that surrounds it. But this is the Art of Bulgari exhibition, which celebrated 130 years of the brand at the Tokyo National Museum late this year. And this watch – the Bulgari Roma – is very important to the Italian jewellery house. It’s the brand’s first ever wristwatch, and the tale behind its genesis and their almost accidental entry into the world of watchmaking is a fascinating one.
