Two-push Chronographs without Column Wheel

The two-push chronograph without column wheel shown in Fig. 107 is made by Le Landeron, of Le Landeron, Switzerland. The trade mark or sign of this factory is the letter L in a shield as shown in Fig. 108 and as with the Valjoux, the movement, no matter what name has been given to it, can be recognised by this sign.
