These are the Dial Clock circuit diagrams.

This is the power and push-button assembly.
It lies behind the clock and is under the display. The battery is lithium poly, flat. It has an attached charger with USB-C connector.
It connects to the Processor board by a 6-pin flat cable.
The clock and microswitch connect to the Processor board by a separate cable

Left Main Board

The Processor Board lies under the Display and is in front of the the Transmitter.
The Processor uses nearly all of its signal pins, since this project expanded its capabilities over the course of development.
The DS3231 is a module which originally included a tiny soldered-in battery, but now has an external CR2032 instead, which required soldering wires to the module.
This module did not have the 1 Hz pin connected to its header, but I managed to solder a fine wire directly to the chip's #3 lead.
The I2C pullup resistors are in the module.

Processor

The Transmitter lies at the back because it includes the programming connector and antenna. It's design is the same as several of my previous projects. It connects to the Processor Board by 4 jumper wires.

Transmitter Circuitr

This character OLED display has a 20-pin header, but only needs 5 because it has I2C protocol selected. Since it is usually off, isolating diodes and a transistor were necessary for the SDA and SCL leads to prevent current leakage from the I2C pullup resistors. It connects to the Processor Board by a 5-pin jumper cable
