Made by a small Hong Kong company since 1968, this calendar & clock will keep you going in the smartest way possible. The moulded plastic box houses day, date, month & 24 hour interface. The numerals measure 35mm, the letters 25mm.
Overall the calendar measures 305x216x78mm. Amazingly it runs off a small battery, with a life of 3 years. Quartz based accuracy.
If you prefer this also has a stand, so it can sit on your desk.
