The Landeron 4750 was the first Swiss electric movement, appearing in 1961.

The movement was developed by the Landeron Branch of Ebauches SA (ESA), Neuchatel, Switzerland...and then named after this branch office.

You'll never see "Landeron" on the dial of a watch containing this movement, and even looking at the movement, you could be forgiven for not making the connection. All of the watch manufacturers listed below used this movement and most have their own name on the movement plates. You'll need to look through a loupe for the Landeron mark and "4750" stamped into the base plate:

The following watches all contain the Landeron 4750 movement:

• Camy
• Clinton
• Everite
• Hamilton Huguenin Electrics
• Rotary
• Teriam
• Tradition
• UNIC
• Vido
• Waltham
• Wittnauer

There is also a Landeron 4760, which is virtually identical to the 4750, only differing by having a hacking feature. Both the 4750 and 4760 are examples of Fixed Coil System, Contact Controlled .
