A life outside the Royal Oak: Audemars Piguet Jules Audemars Metropolis.
Of course, the Royal Oak is a strong model in the Audemars Piguet collection, but, in my opinion, not at the point to make us forget some marvels, in the vintage world, or in the modern universe.
There are some AP which I hold in very high consideration, such as the Millenary Starwheel in steel, some Minute Repeaters, Perpetual Calendars, or... This Jules Audemars Metropolis.
Why? Simple! I love the combination of a perpetual calendar and a world time, and I find that the Metropolis is an exquisite watch, with its superb dial and nice case.
Here it is, in platinum. Credit picture: Antiquorum.
What about your AP outside the Royal Oak?
