The Favre Leuba 105 watch movement features a pin-lever escapement and a unique design where the train and hand gears are driven separately by the barrel. It is a manual wind movement that includes a sweep second hand. The movement is equipped with a day function that can be set by +/-24 hours and a date function that can be quickly adjusted through reverse setting. The Favre Leuba 105 movement was predominantly used during the period roughly around 1975.
