Or if you want a bit more of a challenge, you might consider the DS3231
https://datasheets.maximintegrated.com/en/ds/DS3231.pdf
This is a full-featured real time clock with a TCXO. It has a programmable
32KHz or 1 pps output. You can trim the frequency digitally via an I2C port
in increments of about 0.1 ppm.It comes in a small package but you can get
the Chronodot, a breakout version with 0.1" headers from Adafruit and
elsewhere:
https://www.adafruit.com/product/255
You can use the Chronodot by itself or hook it to an Arduino to access the
full range of features.
