The outstanding Seiko Credor Spring Drive Minute Repeater
One of the most accomplished minute repeaters to be launched in recent years is the Seiko Credor Spring Drive Minute repeater. It has some very interesting construction features including a double case for resonance: the hammer strikes a pin that strikes the gong which is outside the inner case holding the movement. And the alloy for the gong is made by a craftman whose family has been making wind chimes for 800 years. More on this later. The sound is clear, loud and resonant – outstanding.
