New watches are rarely considered a big deal; anniversary editions are what collectors look out for. Bulgari, also known for its jewellery, is celebrating the 20th anniversary of its Diagono watch with a few additions to the collection. Pink gold has been used for the first time and standouts include the Diagono Complication (above; HK$237,000), with a pink-gold case and brown alligator strap. Featuring a moon face, this extra-large (42mm dial) piece will look great on men and women. If you think the timepiece is too valuable for everyday use, consider the Diagano Classic (HK$21,300), which has a 29mm dial, a stainless-steel and rubber case and a black rubber bracelet. The collection will be available at the end of this month at all Bulgari locations, including Chater House, Central, tel: 2523 8057.
