Hermes has a knack for fusing function and fashion and the newest Passe-passe watch is no exception. The design features an interchangeable leather strap and a tiny screw that easily pops off to release the stainless-steel face from the band. Available in three sizes, each watch comes with a standard black calfskin strap and an additional strap, in a choice of colours, in calfskin or alligator (far left; from HK$14,900 to HK$17,700). For something truly luxurious, why not choose the diamond-set version, which is available in either the small or medium size (left; HK$50,500 to HK$59,800)? The collection is available from all Hermes locations, including the store at Pacific Place, Admiralty, tel: 2522 6229.
