Lange & Söhne Zeitwerk Date reference 148.038 in 18k white gold was introduced at SIHH 2019 and remains in current production. Collectors prioritize this reference for the Calibre L043.8, which integrated a peripheral date ring—a first for the digital-display family—and doubled the power reserve to 72 hours via a twin mainspring barrel. The 44.2mm case houses a solid silver grey dial featuring the signature \"time bridge\" made of rhodiumed German silver. This model marked the tenth anniversary of the Zeitwerk line and introduced a quick-set pusher at four o'clock to advance the hour display independently. On the secondary market, this reference typically trades in the $85,000 to $105,000 range. A notable technical detail is the inclusion of a constant-force escapement, which manages the significant energy required to advance the three jumping discs and the date ring simultaneously."}, "listing_stats": {"count": 9, "median": 59000.0, "low": 16850.0, "high": 99000.0, "brands": 1, "merchants": 2}, "listings": [{"id": "h_7670123921495", "title": "A.
