Our second most popular calendar clock.

Utilising the exact same calendar section as the wildly popular G239a clock, but reducing the clock-face right down to alarm-clock size means this can easily be used as a desktop unit.
It's flat bottomed so perfect for a bedside table, mantle piece or a desk at work. Alternatively you can hang on the wall like its larger sibling.

The G236a has a small 70mm diamter clock-face linked to a fully automatic calendar.

It features Twemco's patented Perpetual Calendar technology that automates the long and short months and also leap years. A true 'set and forget' calendar clock.

A single size C batteries, which should last you a couple of years or so depending on the brand, is supplied with the clock.
There's a high quality German movement at the heart of the clock that will provide you with an accuracy of about 1.5 sec/month at normal operating temperatures.

Clock operation is straightforward:
Time is adjusted via a wheel on the back of the movement situated behind a removable panel on the back of the clock.
The date is adjusted via sliders, also on the back. All the instructions are printed on the clock so you can never lose them..
