: I should mention, that this movement is one
: that I have not previously seen before. It's
: operation is unusual as well... The pusher
: at 2 o'clock starts the chronograph, while
: the pusher at 4 o'clock both stops and
: reset's the chronograph. One can restart the
: chronograph by pushing the 2 o'clock pusher
: again, but this arrangement is not as
: convenient or as natural of a movement as
: the traditional 2 o'clock start/stop, 4
: o'clock reset arrangement.

: Does anyone have any ideas as to the source of
: this movement?

Hi, Chuck

it's obviously a Landeron 248 movement, recording chronograph with two pushers, without pillar wheel. Landeron was a branch of 'Fontainemelon Watch Factory Le Landeron' Switzerland, as part of Ebauches S.A, Neuchatel, Switzerland, nowadays known as ETA. You will find as marking an 'L' in a stylisized cloud and the number 248 under the the balance wheel.

Please find enclosed a link to a german website for specifications and photos of the movement.

cheers, Martin
