I had the chance this weekend to visit the JLC Sound Maker Exhibit, which is currently in NYC. It was a terrific opportunity to see 140+ years of minute repeaters from the manufacture, with a diverse array of pocket / watch styles. There was even a watchmaker present to explain the mechanics of the MR mechanism with a real, working movement example. Apologies for the poor photos as these were all taken from my phone. For those in the NYC area, it is worth a visit.
