Ultra-thin Luxury Sports Perpetual Calendar

Since reinventing the classic Overseas collection in 2016, Vacheron Constantin has been pushing the boundaries of luxury sports watch sophistication. Today, the Overseas collection not only features a perpetual calendar, but also a skeletonized perpetual calendar, a skeletonized tourbillon, and even a super-complex minute repeater, tourbillon, and perpetual calendar. Vacheron Constantin is undoubtedly a pioneer in the ultra-complex luxury sports watch market! This year marks the brand's 270th anniversary, and recently, the brand released two new Overseas Ultra-Thin Perpetual Calendar models: one with an 18k rose gold case and a gold dial, and one with an 18k white gold case and a burgundy red lacquer dial.

This year marks the 150th anniversary of Audemars Piguet. In this crucial year, Audemars Piguet launched the Royal Oak and Code 11.59 perpetual calendars, both of which were stunning watches with single-crown adjustment. Just when we all thought Audemars Piguet had finished releasing new watches this year, they recently released a 38mm version with the same features. While the 38mm version lacks the weekly calendar function, it's noticeably more refined and compact than the 41mm version. This makes the Royal Oak, in particular, comparable in size and comfort to the "Jumbo," a truly impressive model.

Like the 41mm version, the 38mm version is equipped with the 7136 caliber, a new generation of Audemars Piguet's ultra-thin 7-series automatic movements, enhanced with a single-crown adjustment module for the perpetual calendar. Originally developed specifically for the "Jumbo" model, the 7-series automatic base movement is a mere 3.2mm thick and boasts a 52-hour power reserve. With the addition of the perpetual calendar, this power reserve has been increased to 55 hours. This movement not only utilizes the same internally-adjusted balance wheel as the RD3, but also features a separate balance spring fixing bridge. This unique design not only provides excellent shock resistance but also allows for the first glimpse of a balance bridge with no surrounding elements. It's truly stunning! Ultimately, this legendary movement allows the 38mm Royal Oak Perpetual Calendar to be kept to a mere 9.4mm in thickness!

When it comes to ultra-thin watches, Piaget is a brand that should be mentioned. The recently released Polo Blue Obsidian Ultra-Thin Perpetual Calendar not only represents Piaget's expertise in ultra-thin watches, but also showcases its deep roots in jewellery. Crafted from 18K white gold, the case measures 42mm in diameter and is only 8.65mm thick, water-resistant to 30 meters. Its blue obsidian dial is formed from mineral-rich sulfide liquid that solidified on rock, resulting in a naturally iridescent luster. Because it is a natural stone, each watch is unique. The perpetual calendar is clearly laid out, and the moon phase at 6 o'clock vividly depicts the dappled landscape of the lunar surface.
