I recently did a lot of work to the dash of my 1981 280zx - changed out the speedometer, heater control valve and while I was doing it I installed an original analog clock that I bought some time ago. The clock originally in the car did not respond to setting the hours and occasionally would change time or start to flash. I don't know if it would be at all useful. One of my hobbies is to restore antique clocks but there was no need for me to take this one apart. If you are interested email me at Chainechat@Yahoo.com
