Omega's Speedmaster has a world-famous title: the "Moonwatch." It was the chronograph on the astronauts' wrists when humankind landed on the Moon. But this watch's most moving moment came not in the glory of the landing, but in an accident that nearly turned to tragedy.

In 1970, the Apollo 13 spacecraft suffered an explosion on its way to the Moon; the power system was badly damaged, and the electronic timing instruments aboard could not be used. To return safely to Earth, the astronauts had to manually fire the engine for a correction at an extremely precise moment, a hair out, and they would slip past the Earth and never come home. At that life-and-death juncture, they relied on the purely mechanical, power-free Speedmaster on the wrist to precisely count the crucial fourteen seconds. In the end, the three astronauts came home safely.

In that desperate situation where countless precise electronic instruments had failed, one reliable mechanical watch guarded three human lives. This carried the weight of the word "reliable" to its extreme: real value lies not in adding lustre in fair conditions, but in whether it holds firm and can be trusted at the most crucial, most difficult moment.

For any professional service, "trustworthy" is the highest praise. Good skill and a fine manner matter, of course, but what finally lets people entrust themselves again and again is the reliability of "whatever happens, it will not let me down." Trust is slowly earned by holding firm at the crucial moment, time after time.

What Hair Diva believes in is that same professionalism grounded in "reliability": what we want to be is the choice you can entrust yourself to every time, that will never let you down. Like the Speedmaster on Apollo 13's wrist, at the moment you care about most, we steadily guard the result you want.
