Despite being founded in 1891, the Swiss business Angelus did not truly come into its own until the First World War, producing outstanding in-house and fairly inventive sophisticated movements. In 1939, Panerai used the Angelus 8 day movement for some of its military watches, demonstrating the robustness and versatility of their mechanical movements.

But it wasn’t until the release of the 'Chronodate,' one of the first series chronograph watches with the appearance of a calendar on the dial, that catapulted Angelus into the spotlight in 1943. It was a triple calendar that used the cal. SF217, a superior in-house mechanism, and was eventually dubbed 'Chronodato'. A red hand pointing to a chapter ring on the dial, as well as the 'jump day and month windows' at 6 and 12 o'clock, indicate the date. Preserved in excellent overall condition the watch has developed through the years a warm and gentle patina onto its two tone dial. Its warm tobacco-brown hue contrasted with the outer black ring used for displaying the date of the month renders the timepiece both equally sporty and elegant at the same time.
