Gruen made some fantastic watches in the 1930s, 1940s and 1950s. Their Curvex range was a work of art! But like a lot of companies in the late 1960’s / early 1970’s, they seem to have lost their way and jumped on the fashion bandwagon. To read about this interesting company, try this excellent site.
The first group images below show mainly PUW based Gruens; see the caption under each image for more information.

- PUW 907 movement from one of the Gruens; it is a moving coil, contact controlled movement. The first document PUW electric movement is the PUW 1000, so the PUW 907 is a bit of a mystery although it looks virtually identical to the PUW 1000.
-
- PUW 2508 movement from one of the Gruens. PUW 2508 is a transistor (IC) controlled, balance wheel movement.

Now a real rarity! The Gruen Electronic Jump Hour watch! One of the very few watches to have used the ESA 9159 movement…and very hard to find today. This one is in exceptional condition.

- From the balance side, identical to a standard ESA 9158 apart from the stamped “ESA 9159” in the plate.
-
- Dial side is very different; you can make out the calander wheel on the left hand side then an additional brass plate to support the minute and hour wheels.

- NOS ESA 9159 movements can still be found.
