Seiko by Hanae Mori: a reversible two-dial gold-plated watch
This Seiko by Hanae Mori watch is a collector's piece as rare as it is elegant, the result of a collaboration between Seiko and the great Japanese haute couture designer Hanae Mori. Its round gold-plated case is reversible: it pivots on its axis, in the manner of a Reverso, to reveal two radically different dials. A singular horological object, both jewel and watch, which can be worn just as well on a man's wrist as on a woman's.
The first side features a white lacquered dial adorned with black Roman numerals and the "HM" signature, in a classic, timeless elegance, framed by a bezel with exposed screws in a porthole style. The second side reveals a minimalist black dial with a faceted sunburst pattern, enhanced only by the gilded "HM" signature, in a resolutely graphic and dressy spirit — day and night, in a sense, brought together in a single watch. Each side has its own hands.
This Seiko is driven by a double quartz mechanism (caliber 2N20): each side has its own movement and its own crown, allowing the time on each dial to be set independently. Reliable and precise, it carries forward the legacy of Seiko, pioneer of quartz with the Astron in 1969. The reversible mechanism has been tested and works perfectly.
With its 30mm case in gold plating and its ingenious reversible system, this Seiko by Hanae Mori offers a dressy and refined format, on a man's wrist as on a woman's — a true Unisex watch. The two original dials are immaculate; the case shows light micro-scratches from use and the Crystal a few scratches on the black side. It is fitted on a black alligator leather handmade strap, non-original, with a gilded Buckle.

Frequently Asked Questions
Who is Hanae Mori and why is this watch special?
Hanae Mori (1926-2022) was one of Japan's greatest haute couture designers, the first Asian woman admitted to the Paris Haute Couture Syndicate. Her horological creations, produced by Seiko under the signature “Seiko by Hanae Mori,” are collector's pieces sought after for their singular design and rarity.
How does the reversible system work?
The case pivots on its axis, between the lugs, to reveal the second side — a principle inspired by the Reverso watch. Each side has its own dial, hands, and crown, allowing the time on each side to be set independently. The mechanism has been tested and works perfectly.
Is the case solid gold?
No. It is a gold-plated case on a metal base. This generous golden finish offers the radiance of gold and fully contributes to the precious, dressy character of this collector's piece.
Is this watch suitable for a man or a woman?
It is a Unisex watch. With its 30mm diameter and dressy design, it is equally suited to feminine wrists and masculine wrists that appreciate compact, refined formats.
