From Héron
The Mirabel Firehorse is a limited-edition Lunar New Year watch. It draws inspiration from the red envelopes given to children during the New Year, often filled with small amounts of money for good luck. A simple and grounded take on a watchmaking tradition usually seen only in the ultra-luxury segment.
