The first ever Double Rattrapante Chronograph. This watch features: Black colored solid silver dial & silver sub-dials, with Applied Roman Numeral & Index Hour Markers. Double split means that both the seconds & minute hand can split & maintain a separate 30 minute counter from the original. Traditional split watches only have a split second - which allows for timing an additional increment of up to 60 seconds. This watch allows for an additional timing of up to 30 minutes. Chronograph movement with flyback function - allowing the stop-watch to be instantaneously restarted for continuous timing, without having to stop, reset and then restart the chronograph. Furthermore the minute hand of the chronograph jumps in 1 minute increments rather than continuously moving - this allows for accurate reading of the timing function. The movement has 40 jewels & beats at 21,600 vph. The movement has an approximate power reserve of 36 hours.
