Mainspring for German & English Clocks – Hole End (17.00 mm x 0.45 mm x 1800 mm)

German English Clock Mainspring 17 X 0.45 X 1800Mm – Hole end

This German English clock mainspring 17 x 0.45 x 1800mm is a replacement power spring for compatible German and English mechanical clocks. It uses a hole end and measures 17mm wide, 0.45mm thick and 1800mm long.

The mainspring stores the energy that drives a mechanical clock after winding. Correct width, thickness, length and end style are essential because these dimensions affect whether the spring fits the barrel or movement and how much power it delivers.

This replacement is intended for repair and restoration where the original spring is broken, weakened or otherwise unsuitable for reuse. It is particularly useful for clockmakers and experienced restorers who can compare the original spring dimensions before installation.
