The new Replica Royal Oak Self-Winding Perpetual Calendar Ultra-Thin — casually and affectionately known as the RD #2 — falls in the former category of strategic incremental improvements that edge closer to perfection.While it can’t claim this anymore, there is no disregarding that a 6.2mm thickness is still absolutely wild for a mechanical wristwatch, let alone a self-winding perpetual calendar of this caliber .

That 6.2mm-thick measurement is the fully encased and ready-to-wear watch. Crafted in titanium, the 41mm-wide RD#2 exemplifies the high standard of finishing that Paying Audemars Piguet Replica Watches China With Bitcoin has for its watches, and the dazzling results it produces compared to some other recent titanium releases. Housed inside is the Calibre 5133 — the same movement as the previous RD#2 variants — which clocks in at only 2.89mm-thick.

This ultra-thin perpetual calendar movement displays the day, date, month, and moonphases, tracks the leap year, provides a day/night indicator, and, of course, hours and minutes. You can observe the movement comprised of 256 parts beating away at 2.75Hz (19,800 VPH) through the sapphire caseback.

The most obvious update is the dial. Beneath the flat sapphire crystal is a smoky blue-to-black gradient with a sunburst finish. It lacks the tapisserie dial the Cheap Audemars Piguet Royal Oak Replica is known for, which can be found on the first-generation RD#2, but makes up for the somewhat flat appearance of the vertically brushed second-generation dial.

The addition of snailed (concentric circle) black subdials provides immediate contrast, improving legibility while also giving the ultra-thin watch a sporty appearance. A full titanium case and bracelet construction with brushed surfaces and polished bevels, instead of the mixed metal and polished scratch-magnet bezel of the previous generations, rounds out the shift to a more athletic-designed sports watch. Despite this shift, the RD2 retains its 20m water-resistance rating.

With a perfectly balanced dial, ideal case material, functional finishing, and an effortlessly elegant movement, the newest Buying Audemars Piguet Royal Oak Self-Winding Perpetual Calendar Ultra-Thin Watches With Crypto checks all the boxes of the horological endgame, even the limited-edition box.
