Blancpain Concept Hunting Suit Watch, model: 4563-3642-55B, diameter 39mm. This watch follows the appearance of a hunting pocket watch and adopts a double-layer protective cover design. However, unlike hunting pocket watches, Blancpain has made a round hole of just the right size on the front cover. This way, even without opening the rest, the time, month and day of the week can be clearly read! Limited to 200 pieces worldwide.
