Audemars Piguet marks 150 years with a limited-edition Royal Oak and a Code 11.59 collection
Royal Oak Perpetual Calendar
Limited to 150 pieces, the Royal Oak Perpetual Calendar Openworked '150th Anniversary' stands out for its technical brilliance and historical significance. This 41mm timepiece marks the swan song of the legendary Calibre 5135, which has powered AP's openworked perpetual calendars for nearly a decade.
The case and bracelet are crafted from lightweight titanium, enhanced by shimmering Bulk Metallic Glass (BMG) on the bezel, caseback frame, and bracelet studs. This palladium-based alloy – renowned for its resistance to wear and corrosion – lends the watch a mirror-polished glow.
At its heart lies the Calibre 5135, an evolution of the perpetual calendar lineage that began with the groundbreaking Calibre 2120/2800 in 1978. Its openworked design reveals the intricate skeletonisation and hand-finishing, visible through both the sapphire dial and caseback. The perpetual calendar automatically adjusts for the varying lengths of months and leap years, with a moon-phase display at 6 o'clock offering a photorealistic depiction of the lunar cycle based on NASA imagery. The twin moons reflect both the northern and southern hemispheres — a nod to the universal nature of time.
The dial draws inspiration from a historical pocket watch (ref. 25729) housed in the Musée Atelier Audemars Piguet"

Code 11.59 Grande Sonnerie Carillon Supersonnerie
Along with the special Royal Oak, AP's Code 11.59 collection introduces two special '150th Anniversary' Grande Sonnerie Carillon Supersonnerie models. The Grande Sonnerie is among the rarest and most complex complications in watchmaking, with the ability to automatically chime the hours and quarters. The Supersonnerie mechanism enhances the sound's clarity and resonance, further elevating the acoustic experience.
One of the new Code 11.59 150th anniversary models features a mesmerising natural opal dial, a study in light, hue, and texture. It pairs an 18-carat pink gold case with a rare harlequin opal dial – a kaleidoscope of green, blue, red, and yellow hues that shift with the light. Its shimmering green inner bezel frames the dial, while pink gold hands and hour markers provide elegant contrast. The other special-edition Code 11.59 features a sapphire dial, offering an enchanting view of the hand-wound Calibre 2956 orchestrating the chiming complication. The case combines sand gold with a black ceramic case middle and crown, framed by a sand gold and rhodium-toned dial.
The Grande Sonnerie mode strikes the hours and quarters, while the Carillon mechanism employs three gongs and hammers to create a richer soundscape. The Supersonnerie's patented construction optimises sound transmission through the case, ensuring exceptional acoustic clarity and volume. Each of the five new Code 11.59 references, including the two anniversary specials, reflects AP's mastery of mechanical complexity and aesthetic finesse. The balance of materials, intricate dial textures, and the resonant chime of the Supersonnerie elevate the collection into the realm of haute horology's finest creations.
In its 150th year, AP remains true to its founding spirit – continuing to blend technical audacity with timeless artistry. These three masterpieces are not just watches; they are at once a nod to the maison's incredible legacy and an assertion of its future direction, captured in an eclectic mix of metal and glass, and measured in flawless time.

Las Vegas Sphere team to design Starlab space station with wellbeing in mind
A new commercial space station is being designed to feel 'less like a machine', as competition heats up to replace the ageing International Space Station. Starlab, being built by Voyager Space and Airbus, is working with design company Journey and hospitality company Hilton to shape the interior of the station, scheduled for launch in 2029. The International Space Station (ISS) has been operational since 2000, with Nasa, Russian and other international astronauts who have continuously occupied the outpost. But the station is set to retire in 2030, and Nasa is backing projects such as Starlab, Blue Origin's Orbital Reef and Axiom Space's Axiom Station to maintain a US presence in low-Earth orbit, otherwise, China's Tiangong would be the only operational station. Vast Space, not part of Nasa's programme, is also developing its Haven stations. Brad Henderson, chief commercial officer at Starlab told The National that a space station should have a 'sense of place'. 'Journey is helping us ask the right questions: where will people gather at the end of a long day? How do you create a psychological balance between work and rest in microgravity? They're real, daily considerations for astronauts spending months in orbit, not abstract design challenges,' he said. 'One area where this really comes through is in the design of communal zones. Instead of sterile corridors, these areas are being shaped as spaces that invite collaboration, reflection and routine.' Journey is a global design agency whose portfolio includes the Sphere in Las Vegas, the Empire State Building observatory in New York and the Sun Princess Dome for Princess Cruises. It is bringing hospitality and environmental design experience into the station and will combine it with the decades of aerospace and astronaut insights that Voyager Space and Airbus has. 'That partnership allows us to test concepts through human evaluations and analogue environments,' said Mr Henderson. 'Journey observes and adapts, and we help shape scenarios that mimic the operational tempo and physical demands of space flight.' Hilton is contributing its experience in comfort, wellness and service. Together, they are exploring how elements like lighting, acoustics and personalised storage can support rest and recovery, something critical for both physical and mental health in long-duration missions. Technology is also being built into Starlab from the start, with autonomous operations that would help improve crew experience. Starlab has selected Palantir Technologies to handle the station's data and software systems. The company will create virtual models of the station, known as 'digital twins', to track its performance, forecast maintenance work and manage resources. The tools are intended to support mission planning and routine operations to reduce workload on the crew. On designing for microgravity, Mr Henderson said: 'Instead of simply minimising the disorientation of microgravity, we're asking how the environment can embrace it. How can we guide movement, orient the body, or signal zones without relying on gravity?' How Starlab compares to other private stations Unlike the ISS, which was assembled in orbit, Starlab is designed to launch fully assembled on a single SpaceX Starship flight. It will consist of a habitat and laboratory module, as well as a service module for propulsion and power. The station will have about half the habitable volume of the ISS but is expected to match its scientific capacity. The other private stations also have a different design approach, Orbital Reef's mixed-use model to Vast's smaller, rapidly launched platforms. Vast Space's Haven-1 started out as a single-module station designed for short-duration missions, with plans to expand into Haven-2 by docking additional modules and including artificial gravity. Axiom Space is building a modular station that will first attach to the ISS before becoming independent, with an expected launch date of 2028. Starlab, in comparison, is much larger and fully integrated from the start, requiring SpaceX's Starship for launch because no other rocket is powerful enough to carry its single, large module into orbit. Starlab has passed several Nasa safety and design reviews and is building a full-scale mock-up for astronaut testing. 'Our goal is to build a station where astronauts can carry out critical research while living in an environment that supports their well-being,' Mr Henderson said. 'It's about making sure they can perform at their best, day after day, in one of the most challenging environments imaginable.'

Trump announces peace agreement between Azerbaijan and Armenia
Azerbaijan and Armenia signed a US-brokered peace agreement on Friday during a meeting with U.S. President Donald Trump that would boost bilateral economic ties after decades of conflict and move them toward a full normalization of relations. The deal between the South Caucasus rivals - assuming it holds - would be a significant accomplishment for the Trump administration that is sure to rattle Moscow, which sees the region as within its sphere of influence. "It's a long time - 35 years - they fought and now they're friends, and they're going to be friends for a long time," Trump said at a signing ceremony at the White House, where he was flanked by Azerbaijani President Ilham Aliyev and Armenian Prime Minister Nikol Pashinyan. Armenia and Azerbaijan have been at odds since the late 1980s when Nagorno-Karabakh, a mountainous Azerbaijani region mostly populated by ethnic Armenians, broke away from Azerbaijan with support from Armenia. Azerbaijan took back full control of the region in 2023, prompting almost all of the territory's 100,000 ethnic Armenians to flee to Armenia. Azerbaijan President Ilham Aliyev holds a signed trilateral agreement. Trump said the two countries had committed to stop fighting, open up diplomatic relations and respect each other's territorial integrity. The agreement includes exclusive US development rights to a strategic transit corridor through the South Caucasus that the White House said would facilitate greater exports of energy and other resources. Trump said the United States signed separate deals with each country to expand cooperation on energy, trade and technology, including artificial intelligence. Details were not released. He said restrictions had also been lifted on defence cooperation between Azerbaijan and the United States, a development that could also worry Moscow. Armenian Prime Minister Nikol Pashinyan holds a signed trilateral agreement. Photos: AP Both leaders praised Trump for helping to end the conflict and said they would nominate him for the Nobel Peace Prize. Trump has tried to present himself as a global peacemaker in the first months of his second term. The White House credits him with brokering a ceasefire between Cambodia and Thailand and sealing peace deals between Rwanda and the Democratic Republic of the Congo, and Pakistan and India. However, he has not managed to end Russia's 3-1/2-year-old war in Ukraine or Israel's conflict with Hamas in Gaza. Trump on Friday said he would meet Russian President Vladimir Putin in Alaska on August 15 to work on ending the war in Ukraine. Reuters
