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.
And the earlier Credor sonnerie with its lingering chimes thanks to a miniature orin bell like those found in Japanese temples. This sound has a very much more Japanese aesthetic.
And another Seiko chiming timekeeper - it's a long video at nearly two minutes.
