It is a chronometer, and it feeds the required computers GMT and elapsed time and date. Every A320 must have one but in a different location. I never worked the A320 so perhaps a little help (VC10 to confirm). But for example on the MD11 the chronometer is in the maintenance panel by the r/h observers seat (old f/e's station). Not easily accessable unless the pilot left his/her seat. The chrono feeds the display electronics unit which sends the time in digital format to the captains and f/o's navigation display (ND). This is where the crew reads the time as well as an elapsed time function and trip timer. It also sends GMT/date information to the flight management computers and other computers which utilize time. The first thing we're told in MD11 school is "ya see this clock, well, its a no go item". And so it is.

Well, if you care to look carefully, you can see that there seem to be two basic locations for the chronometer (which it is). One is right below the gear handle, the other one right above the gear handle. Also you can see that on the left of the EICAS there are different types of configurations for stand-by instuments.
I suppose that the location of part of the instuments is part of the airline specific items every aircraft manufacturer offers. Also certain items and their location are mandated differently by JAA of the FAA, or any other governmental aviation oversight agency.
I don't know the exact reason, but maybe someone from Airbus will read through this and enlighten us.

stop guessing, you found the answer:
the A320 family clock has, on latest aircraft- been
a) modified for new type of "GPS clock"
b) placed differently on the panel to make room for -future- installation of the
ATSU (air traffic service unit) display an interface panels (2)
They will become available with future FANS standards.
have fun flying airbus aircraft

At NWA this is one way of distinguishing the 319 from the 320. The 319 clock is above the gear handle and the gear lights are smaller. The clock on the 320 is placed below the gear handle and has larger gear lights. I too have to agree that the 319 setup has something to do with the future panel setup for fans equipment.
