The stone cold classic.

These clocks are most famous for having been Barclay's Banks go-to clocks for their branches up and down the country for many years. In fact we still get units from the 80's coming back to us for servicing (not from Barclay's it has to be said, mainly from collectors).
Originally they were full metal case and framework inside, and weighed a tonne, then in the mid 90s it was changed over to plastic and the minute adjusters moved to the back of the clocks rather than pegs coming out the bottom.
Rest assured though; the accuracy, build quality and longevity remained in place.

The G225 has a 24-hour time display 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.

Two size D batteries, which should last you a couple of years or so depending on the brand, are supplied with the clock.
There's a high quality, quartz driven, motor at the heart of the clock that will provide you with an accuracy of about 0.6 sec/month at normal operating temperatures.

Clock operation is straightforward:
On / Off switch inside the battery compartment.
Time is adjusted via hour and minute levers situated behind a removable panel on the back of the clock.
