This is a vintage wristwatch created through a collaboration between SEIKO and fashion designer Hanae Mori. The main feature of this watch is its reversible (W-face) design, allowing you to enjoy two different dials by rotating the case. Typically, one side has an onyx black dial, and the other side has a white dial, allowing you to choose based on your outfit for the day. The dial and case are adorned with the "HM" logo, Hanae Mori's symbol. It has a simple design, but its unique mechanism makes it a distinctive watch. It's recommended for everyday use as well as for collections. Currently, it is traded as a rare antique/vintage item. ■Brand SEIKO x Hanae Mori HM Collaboration ■Item Ladies' Wristwatch QZ Quartz ■Model Number 2N20-0070 ■Original Retail Price Approximately ¥150,000 ■Materials GP (Gold Plated) / Leather ■Size Case Width: Approximately 3.3cm Case Length: Approximately 3cm Wrist Circumference: 18cm (Maximum) The battery is currently dead, but it should work if you replace it.
