Hello clock experts,

I’d be grateful for some insight on my latest acquisition. As I understood from the other threads, it’s a Junghans musical carriage clock Joker that plays a tune as an alarm at a set time (the tune keeps playing until the spring unwinds). Everything on it works well so far. Others here mentioned that it was manufactured by Junghans between 1890s-1930s. Is there any way to closer date this clock? I couldn’t find any other markings on the clockwork nor the dial besides the Junghans logo.
It’s my first clock fully made of metal and it’s mostly in a good shape, except for some patina stains here and there. What is a good care routine to prevent any corrosion or deterioration? Should I polish it somehow?

I hope the attached photos are any help.

Thank you for the input and advice!

The year 1890 is the earliest your clock would date based on the trademark on the dial, which was registered in 1890.

I see the Junghans trademark on the upper middle part of the backplate.

Junghans commenced date coding their movements in 1901. I do not see a date code on the movement, which implies a date of 1890 to 1900.

Jokers were popular through the 1930s, but 1890 to 1900 is the best I can estimate.

Perhaps there are some mechanical aspects of your clock that someone could identify to narrow the date.

Regards.

Thank you for the reply and dating. A decade's precision is totally enough. I was also under the impression that this piece would belong to the older end of the manufacturing time span. Do you know by the way how often these clocks are supposed to be wound? The spring unwinds after three days, does it mean it should be wound daily? Sorry if these are obvious questions.

Have a good day,
Jan

Thank you both for your answers. One final question - the alarm jingle doesn't stop until its spring completely unwinds and then it continues playing for some time even after I wind the alarm spring up. How do I stop the jingle? I'd actually like to use the clock as an alarm clock and I haven't figured out how and when to wind the alarm.

You can stop the alarm when it's playing by turning the alarm setter knob past the hour it is ringing. You need to wind your clock each day and wind and set the alarm whenever you want to use it.
