Model Information: The highly original "Ronde Smile Day" designed by Alain Silverstein. This is a rare, discontinued model and a collector’s piece limited to 500 pieces.

The playful design, which gradually transforms into a smile as the weekend approaches, brings a sense of joy every time you look at it.The design, which combines vibrant colors with geometric shapes like triangles and squares, strongly reflects the Bauhaus philosophy. It is a true "work of art" that showcases the unique sensibility of Silverstein, a former interior designer. The case back is see-through, allowing you to admire the movement of the mechanical mechanism. This is a model with a distinctive personality that lets you enjoy both design and the charm of a mechanical watch at the same time. Product Code: 09NJAAAU0001 Retailer: Ginza rasin (Ginza Rasin)
