I have a Gruen Techni-Quadron in a very unique 14K Green and White gold striped Gruen-Weber case. The dial is original. The Gruen-Weber case is original. The movement is the Aegler "Gruen" 877s which is original. The crown is a yellow gold replacement. If you are not familiar with this watch - it is the twin to the Rolex Prince - Same movement and so on. I am trying to find out if there are any other Gruen-Weber 14K Green and White Gold cased watches like this left. I have found some Rolex Prince models in Yellow and White striped gold. I have found one other Gruen with a Yellow and White Stirped gold case - but no other Green and White Striped gold case. I have been collection for 20 years and this is the only one I have seen. Let me know what you think.
