The Landeron caliber 4750 was the first Swiss made electric watch movement. This caliber was launched circa 1960 ~ 1961 and is found in a wide variety of vintage electric watches from the 1960s. There is a similar Landeron caliber 4751 with 13 jewels.

The original battery was numbered WD-4 or WD-5 and contained mercury. For that reason, the battery is no longer available. Some folks use smaller diameter modern batteries with an adapter ring. If you have experience with this, please share in the comments below.
