Wecker Travel Clock Alarm Mainspring 3.0 x .13 x 25" - Made in Germany

German made Mainspring for Wecker Alarm clock, measures 3.0mm x 0.13mm x ~25", tongue end, steel, new in envelope. Could also very well fit in other clocks and perhaps even some watches as well. See images for further details. I'm led to believe this is the ALARM side mainspring (7012 Alarm spring is what the notes I have say). This is a really nice quality mainspring for clocks made in the 1940's and 1950's with these springs being made in 1951. I specialize is hard to find watch & clock parts and all parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
