Tested, known good clock for the speedometer cluster in 1977-1981 Mercedes w123 sedans, coupes and wagons.  Will not fit 1982 and newer w123 vehicles that came with a tachometer. Knob works as expected to adjust the clock arms.

I can combine shipping if you need other items at the same time.  I have some other carpet as well, and not everything I have is listed yet, so feel free to ask. 

The US shipping prices are good for continental USA only, and remote areas such as Puerto Rico, Alaska, Hawaii will cost extra, and if this applies to you, message me for a more accurate quote.
