All of the 70-83 analog clocks I refurbish are original Datsun clocks that have had the mechanical mechanism removed and replaced with an accurate / reliable quartz movement. All other parts of the clock are original and are refurbished to like new condition.
All fit and connections are factory original and there are NO AA batteries.
For the concourse aficionado I can refurbish your clock to the OEM condition. The clock will be rebuilt to original specifications, but the accuracy and reliability are no better than the original clock. Please see pricing for this service.
