The tower has four clocks made in Recklinghausen, Germany by Bernard Vortmann and shipped via Rotterdam.
Each clock face has a diameter of 80 centimetres (31 in).
The tower's base is 13 by 4 metres (43 ft × 13 ft) and it stands 26 metres (85 ft) tall.
The clocks use "IIII" for the number 4 instead of the traditional Roman numeral "IV".

The laying of the tower's cornerstone was done by the 6-year-old son of Rook Maker, the city secretary of Bukittinggi at the time.
