Powerful symbolism.
Poetic expression.
Despite the twists and turns of human history, those of us living in the 21st century still share the basic framework of the seven-day week that has been almost universally accepted since time immemorial. Over the centuries and through various philosophies, these seven days of the week have come to be associated with a particular planet or with the sun or moon.
The numbers seven and eight also carry a wealth of symbolic overtones across the world's great cultures and religions. Seven stands for completion, supreme power, perfection and sacred rest. For its part, the number eight is widely associated with prosperity, good luck, infinity and continuity.
Through careful observation of the natural cycles of the planets, Indian astronomer-mathematicians, followed by astrologers, have determined eight natural 90-minute divisions of the 12 daytime hours between sunrise and sunset, conventionally considered as stretching from 6 am to 6 pm.
The very first dawn period from 6 am to 7.30 am is not counted in calculating the Rahu Kaal "windows in time" for each day of the week, meaning seven out of eight are used as strategic periods to fulfil the intuitive human need to put our thoughts in order.
Owners of mechanical timepieces are keenly aware of the all-important power-reserve indication, which reveals the state of energy of a watch or clock, or how long a watch or clock will continue running without being wound. With the Borgeaud SEPTAGRAPH™, the evocative curved stylised arrow, emerging from the SP (Strategic Period) capsule, serves as a "time-reserve indicator" that shows the flow of intensely personal time during a full one and half hours when the world keeps turning without the wearer taking any ostensible action.
Running between 3 and 4 o'clock, the "reverse hour-glass", fills up with a colour that gradually drains away during the 90 minutes of the current "strategic period". It is carefully synchronised with the dedicated off-set counter and its jumping hand indicating the day of the week and the start of each corresponding period. Exceedingly clever and prestigiously seductive, it proves a supremely useful tool in setting appointments with oneself, obviously with others, and thus in planning a well-balanced weekly schedule.
