Arsa Chronograph “Landeron Hahn” – 1930s/40s A rare and characterful vintage chronograph from Arsa, dating to the 1930s/40s. This example stands out for its originality, retaining both its branded movement and caseback—something seldom seen in pieces of this era. Powered by the uncommon Landeron Hahn manual-wind chronograph movement, it offers both mechanical charm and historical interest. The dial is particularly striking, featuring a light blue tachymeter scale that adds depth and vintage flair. Dimensions: • 36 mm case (excluding crown)  Recently serviced and in very good working order, both timekeeping and chronograph functions perform as they should. A scarce, all-original early chronograph—honest, wearable, and highly collectible. All sizes are approximate. TRACKED & INSURED SHIPPING. Private transaction, sold from private collection.
