Quartz movement clock with perpetual calendar

Updated Feb 3, 2025:

I have uploaded the correct day of week week hand file. I also uploaded two other files to reduce stickiness and friction, monthGear2.stl and dateIdlerRetainer2.stl.

Original Post:

I modified some parts to hold 5x10x4 bearings for smoother operation. The three parts that has been modified to fit the bearings are the 24 hour cam, week drive gear, and the hour idler gear. The names of the corresponding stl files are 24hCam.stl, weekDriveGear.stl, and hourIdlerGear.stl. The various modified parts have been uploaded to tinker cad here:

The MR105-2RS ball bearings can be obtained on amazon.com.

The 5V 2A power adapter USB Wall charger can also be got on amazon.

You will of course need a cord to connect the battery lead of the movement to the power supply:

The quartz movement that does not require cutting can also be found on amazon:

For the assembly instruction see the original post of shiura. The parts are printed in PLA, with the front cage and back plate using draft mode for faster printing.

Now I am interested in making a secular perpetual calendar based upon the design of the IWC watch company. This mechanism is supposed to keep an accurate date until 3999 AD!
