This is a very special timepiece that has two cases; an inner one for the movement, and an outer one. The gongs are located in the space between these two cases, to achieve a clear and rich sound.
Just how special is it? Nearly $500,000 worth of special, and so incredibly intricate that Seiko releases only around three of them each year. The watch was introduced by Seiko President and CEO, Mr. Shinji Hattori at Baselworld 2011 just shortly after the Japanese earthquake.
In every aspect of its creation, total purity of sound has been the goal. The result is a lingering, clear and haunting sound which has a uniquely Japanese character.
This beautiful sound has been achieved by the magic of the totally silent Spring Drive mechanism allied to the use of a special steel forged by a celebrated Japanese steelmaker, Munemichi Myochin. For fifty two unbroken generations, members of his family have been master blacksmiths and they have been making steel for over 850 years.
While most minute repeaters follow the traditional hour, quarter and minute system, the Credor Spring Drive Minute Repeater has a decimal system. The hammers strike the hour, ten-minute and one-minute sounds. This system was chosen as being more in keeping with the high technology character of the movement.
It is perfectly logical and simple. At one fifty nine, the hour sound is struck once, the ten-minute sound is struck five times and the one-minute sound is struck nine times.
Treat yourself to the clarity and resonance of the Seiko chimes, then compare it to the legendary Patek Philippe Ref 5016 Minute Repeater. Which do you prefer?
