Patek Philippe has attired the World Time Minute Repeater Reference 5531 in white gold. The dial center is adorned with a new cloisonné Grand Feu enamel motif depicting one of the famous steamships of the Belle Époque fleet still sailing on Lake Geneva today. The result is an entirely hand-made miniature Rare Handcrafts masterpiece. Launched in 2017, this model has established itself as the first minute-repeater that always chimes local time. The caseband and the minute-repeater slide piece feature a hand-guilloched hobnail pattern emblematic of Patek Philippe. The skeletonized lugs ensure an unobstructed view of this guilloché work.
