This NEW OLD STOCK 1970’s massive 47mm. SICURA CHRONO COMPUTER is actually made by BREITLING and houses the EB8800 manual winding movement.
There are four crowns… 1 for setting time, 1 for resetting the minute counter, 1 for rotating quarter-hour ring/bezel and 1 for rotating 5-minute ring/bezel. The center orange chronograph hand counts MINUTES instead of seconds, making it a very practical and easy to read watch for timing events (parking meters etc.) There is also a turning, complicated slide rule bezel inm amazing condition. We just had the manual winding movement cleaned and is accurate. When setting time, the second hand will trace along at the same time. Simply reset to 12:00 with the upper pusher. Any tiny marks on the bezel are just from age, storage and handling over the years. We found this example from a jeweler’s old unsold stock-very uncommon to find in such FINE AND UNUSED condition! Priced very well.
