The late Electro-Chrons seem to be characterised by:

• The wacky hands have been replaced with standard hands.
• Dial markers at hour, minute and half minute intervals
• "ELECTRO-CHRON" on the dial
• One-peice cases without removable backs. They still use the WD-5 battery but it is now fitted by removing the movement through the crystal; the battery is clipped onto the back of the movement.
• Landeron 4760 hacking movement.

In the group of four photos below, the watch is being described as "the new thin Wittnauer Electro-Chron". The reduction in thickness has been achieved by the switch to a one piece case, however I wonder what the consumers and jewellers thought about having to remove the crystal and movement just to change the battery...and all for a reduction of a mere 1.5mm in the overall thickness.

Below is a selection of photographs of these late Electro-Chrons.
