Paul Portinouxfrom the 1970s, housing one of the most reliable mechanical alarm movements ever produced likely the A. Schild AS 1475. As an enthusiast who loves to sell customers on details they didn't know they wanted, you should highlight the dual-crown architecture: the top crown winds and sets the mechanical alarm (indicated by that striking red-tipped squiggled hand), while the bottom crown manages the time and date. It features a classic silver sunburst dial with applied indices and a date window at 3 o'clock, all protected by a robust stainless steel case.
The Incabloc and Antimagnetic designations on the dial and case back confirm this was built as a durable, professional-grade instrument. Flipping the watch over reveals a solid stainless steel back designed to resonate the mechanical chirp or vibration of the alarm hammer. This is an essential acquisition for an elite collector who appreciates mid-century mechanical complications, the "Cricket" legacy of Swiss alarms, and the tactile soul of a manual-wind heartbeat.
