It sounds as good as it looks. A sophisticated alarm watch designed in minimalist taste with a vintage manual winding cal. AS 1931 movement by movement maker Adolph Schild (Schild S.A). This timepiece operates using a dual crown system, with one crown used for time/date setting, the other crown for alarm winding and setting. The Alarm works through a miniature hammer repeatedly “striking” the inside of the pressure case back and is positioned and set by a red center snake hand.
The Retro Alarm’s dial is a porcelain white enamel dial with black painted Breguet style numerals. Dial signed Waldan International or Oscar Waldan. Aperture for Date at 3 o’clock, and red center snake hand for alarm time. Mercedes gold hands with tritium coating or breguet style black hands. Rose gold hand for seconds is centrally mounted and each marker has a tritium point behind it that luminates in darkness and is used in cohesion with the gold Mercedes hands to read the time at night.

Each Retro Alarm’s alarm function is set by a knurled crown at the 4’o clock position. The alarm is designed to sound for 13 seconds on a full wind.

Each Retro Alarm wristwatch has been hand assembled by one of our certified watchmakers to assure that each component is securely in its position and functioning to the standards of a high grade Swiss alarm watch. Of the approximate 330,000 movements produced, in the 1970’s Oscar Waldan purchased a large stock of the 1970-1974 AS 1931 manual winding movement in NOS condition (new old stock) meaning that they had never “left the shelf” or been used/sold. Waldan has a remaining stock of about 150 of these movements left and once gone, this watch will no longer be produced.
