Van Cleef & Arpels is celebrating 50 years of its Alhambra collection whose four-leaf clover motif has become one of its icons. The Sweet Alhambra watches presented this year bring the promise of good luck to the measurement of time. All four feature a bracelet with Alhambra-shaped links in gold and, for some, a mother-of-pearl centre. Diamonds lend a jewellery touch, as do dials in mother-of-pearl, malachite, lapis-lazuli or turquoise. The latter three are limited editions of 50 pieces while the mother-of-pearl dial, matched with creased pink gold and diamonds, becomes part of the permanent collection.
