Breguet 5947

Front and back shots of Breguet's 5947, the Classique Rattrapante (Split-Second Chronograph).  A split-second chronograph has the ability to time 2 events with the same start time; i.e. a race where you start the chronograph with the start of the race stop the first second hand with the winner and stop the other with the runner-up.  As long as both cross the finish line within 60 seconds you know the difference, the "split".

2 shots of the movement, taken with different points of focus in the depth of the movement.  With the added split bridge the movement has about 4mm of visible depth.

The movement is based on the venerable Lemania 2310, same movement that is used in Patek Philippe chronographs and the base of the Omega 321 which drove the original "moon watch" speedmaster
