Featuring a sandblasted titanium case and polished Bulk Metallic Glass, the Audemars Piguet Royal Oak “Jumbo” Extra-Thin Only Watch is sure to exceed its estimated selling price of 320,000CHF and is up there as one of my favourite offerings. The 39mm x 8.1mm case is identical to all other 15202 models, at least in shape, however, in this model, the central case and the bracelet are here made of sandblasted titanium, with the typical dark grey colour resulting from this finishing, contrasting with the polished chamfers.
