Automobile Clock for Car Dashboard Small Analog Quartz Vintage Retro Accessories Mini Stick

Came with NO! instructions - how to set time without breaking the stem or knob for setting time. Please someone, provide instructions and if possible with pictures of how to get to time setting knob to set time, and how to get to battery. I will greatly appreciate such help with all my heart, thank you.

Cute clock, but no instructions. Is the battery replaceable?

Very small. No instructions. Probably not worth the money.
