The first one is the Audemars Piguet watch, it rolled out the Royal Oak Offshore in 2012 and quickly became the hottest diver watches in 2012, and it is still the basic Audemars Piguet watches. In the 2015 SIHH, Audemars Piguet promoted the beautiful silver dial with crystal case back, steel edition: Audemars Piguet Royal Oak Offshore Diver Watches 15710ST.OO.A002CA.02. At very beginning, Audemars Piguet Rolled out 15703 diver watch and it quickly become popular in the world, and later Audemars Piguet promoted several advanced editions (black ceramic, white ceramic, steel and QE limited edition). Please attention: the old steel edition 15703 is off productions, and the black dial and crystal case is replaced. As it is fitted with see-through case back, the dial is adjusted ( which seems to be Audemars Piguet style) so, it is 15710.
When it comes to the IWC, the IWC Portuguese Perpetual Calendar Moon Phase watches could display the waxing and waning of the moon, and this is the first amazing watch that IWC has ever developed. In the staring night, two moons display in the dial, and the moon phase watches are quite precise, and they only has 1 days difference in about 577.5 years. With other three small counters, it appears to be more balanced, and graceful. The single moon phase watches could be adjusted and there are no too much changes on it. Maybe the layout of IWC Portuguese Perpetual Calendar Moon Phase watch is right in this staring night.
