"World's Tallest" 3D Printed Building Unveiled in Switzerland
Swiss universityETH Zurichhas brought the world's tallest 3D-printed tower to the small town of Mulegns, demonstrating innovative techniques that build load-bearing structures without formwork. Named Tor Alva, the new architectural landmark was created in a partnership between the university and the Origen cultural foundation with the aim of enlivening the historic, yet depopulated town, now home to only 11 residents.
ArchitectMichael Hansmeyerand ETH Professor of Digital Building Technologies Benjamin Dillenburger led the design of the building, employing an innovative additive manufacturing process that relies on robot assistance. First, algorithms generate the ornamental and the structural aspects, and then the robots get to work by applying the concrete layer by layer without the need for supportive casting moulds. The innovative load-bearing quality of the design was facilitated by a newly developed reinforcement concept involving the robotic assistants.
The final result is a story tower that comprises 32 sculptured white concrete columns, forming a structure that appears at once naturalistic and futuristic. At the top, the columns unfold in a tree-like formation to create the domed space where visitors can witness scenic views.
For the next five years, Tor Alva will call Mulegns home, after which it can be dismantled and re-erected elsewhere. Starting this weekend, the tower will be open daily for guided tours, and later in the summer, the space will also host staged performances.

German subsidiaries of Swiss solar firm Meyer Burger seek insolvency
After years of financial difficulties and, most recently, short-time working, the German subsidiaries of Swiss solar manufacturer Meyer Burger, with a total of around 600 employees, have filed for insolvency. Meyer Burger Industries in Bitterfeld-Wolfen in Saxony-Anhalt employs 331 people in solar cell production. Meyer Burger Germany in Hohenstein-Ernstthal in Saxony currently employs 289 people in mechanical engineering and technology development. Restructuring efforts to keep the sites open have so far been unsuccessful, according to the company based in Thun, Switzerland. "They will now be continued as part of the proceedings together with a provisional insolvency administrator to be appointed by the court," it said in a statement issued on Saturday. The company should have presented its financial results for 2024 by Saturday. Against the backdrop of ongoing financing talks for restructuring, the company has requested an extension. The company's subsidiaries in Switzerland and the United States are to be retained. Just a few days ago, solar module production in the US state of Arizona, which was still in the start-up phase, was discontinued. Production there aimed to use solar cells manufactured in Germany.

Swiss Watch Exports Surged in April, as the Threat of Higher U.S. Tariffs Loom
Ahead of President Trump's looming tariffs on Switzerland, watchmakers and retailers alike are clamoring to get their hands on timepieces. 1.3 million Swiss watches left the European country in April, totaling $3 billion (2.5 billion Swiss francs). That's an 18 percent increase from the same time last year, according to the Federation of Swiss Watch Industry's latest data, Bloomberg reported. More from Robb Report Meet the Texas Distilleries Working to Show the Effects of Climate on Whiskey Flavor Sara Gilbert Puts Her Modern L.A. Farmhouse Back on the Market for $10 Million H. Moser & Cie. Teams Up With Alpine Motorsports on New Race-Inspired Streamliner Watches The U.S. was the main driver of the surge, making up 33 percent of the market. Exports stateside skyrocketed 149 percent year-over-year to hit a total of $851.9 million—a figure that's equivalent to around a fifth of 2024's total exports to the United States. In particular, timepieces made from precious metals, steel, and bimetallic materials, saw the biggest increases. The drastic jump seen in April is the 'result of early shipments prompted by the announcement of U.S. tariffs,' Jean-Philippe Bertschy, an analyst at investment firm Vontobel, told Bloomberg. The hike is likely a direct response to the tariffs and not indicative of an increase demand, he said. As we mentioned, Trump announced a 10 percent tariff on Swiss imports back in April. Since then, he has discussed adding an additional 31 percent levy if a trade deal isn't struck by July 9; that deadline, however, could be pushed back to a later time, according to Bloomberg. As for the rest of the world, it didn't see a similar surge. Removing the U.S. from the equation, Swiss exports fell 6.4 percent across the globe in April. The Asian market struggled: China had one of the larger drops, with a 30 percent decrease, while Singapore and Hong Kong saw exports drop 9 percent and 23 percent, respectively. The U.K., Japan, and France, meanwhile, saw only single-digit growth, according to WWD. The U.S. tariffs could affect more than just Swiss watches. The levies would impact luxury automakers, too, though they will not apply to cars over 25 years old. The American wine industry, meanwhile, could suffer in the face of any sort of trade war—which could lead to a massive boom on the secondary market. With the Swiss watch industry, though, we'll just have to wait and see how things shake out.

Pre-Owned Watch Sales Spiked by 160% in April Ahead of Trump's Potential Tariffs
Pre-owned Rolexes, Patek Philippes, and more watches were flying off the market last month. In the wake of President Trump's potential tariffs, which were announced in early April, watch collectors responded by snapping up pre-owned timepieces on the secondary market, Bloomberg reported. More from Robb Report Meet the Texas Distilleries Working to Show the Effects of Climate on Whiskey Flavor Sara Gilbert Puts Her Modern L.A. Farmhouse Back on the Market for $10 Million H. Moser & Cie. Teams Up With Alpine Motorsports on New Race-Inspired Streamliner Watches Subdial—a watch dealer and trading platform—usually sees a rush of purchases once payday comes around at the month's end. This time, though, was a little bit different: The site saw its sales jump a whopping 160 percent higher than normal levels, towering over the typical payday increase of 112 percent of other months this year. The U.S. and the U.K. in particular saw an abundance of growth, Christy Davis, Subdial's founder, told Bloomberg. A similar response to the administration's potential tariffs can be seen in Swiss watch exports, too. Last month, watchmakers and retailers across the world were clamoring to get their hands on timepieces from Switzerland before the levies began. As a result, 1.3 million watches—totaling $3 billion—left the European country in April, an 18 percent increase from the same time last year. The U.S., once again, had a strong reaction to Trump's announcement, with stateside exports skyrocketing a whopping 149 percent during the month. The hike is likely a direct response to the tariffs and not indicative of an increase demand, Jean-Philippe Bertschy, an analyst at investment firm Vontobel, told Bloomberg at the time. As for the rest of world, watch exports actually dropped by 6.4 percent in April. This latest pre-owned Rollie hot streak comes after reports that the demand for gold Rolexes on the secondary market is on the rise, with a trio of timepieces from the brand jumping the most spots on Bloomberg's Subdial Watch Index since its inception. The prices of pre-owned Rolexes, as well as Patek Philippes, fell to a three-year low in 2024 after ballooning during the pandemic lockdowns. Through May, Bloomberg's Subdial Watch Index has risen about 5.3 percent, similar to what the market looked like last October, according to the publication. How the secondary market will respond to more levies is an open question. In the meantime, watch obsessives are sure to stay tuned.
