Lange & Söhne Zeitwerk Minute Repeater reference 147.025 was introduced in 2015 as the first mechanical wristwatch to combine a jumping numerals display with a decimal minute repeater. Housed in a 44.2mm platinum case, this reference features the manual-wind caliber L043.5, which utilizes a constant-force escapement to manage the energy required for the instantaneous disc jumps. Unlike traditional repeaters that chime quarters, this model sounds ten-minute intervals, matching the digital time display. The rhodium-colored dial is made of solid silver with a bridge crafted from black-rhodiumed German silver. While the model remains in the current catalog, production is limited by technical complexity to approximately 30 units per year. On the secondary market, this reference typically commands prices between $350,000 and $450,000. A notable technical constraint is the safety system that prevents the time from being adjusted while the striking mechanism is active.", "score": 206}, {"slug": "a-lange-sohne-lange-1-tourbillon", "brand": "A.
