Seiko handled the manufacturing and movement, while Hanae Mori created the design, with the \u003cem\u003eHM\u003c\/em\u003e monogram appearing on both dials.\u003c\/p\u003e\n\u003cp\u003eIts distinctive feature lies in the case. Round, gold-plated, 30mm, it \u003cstrong\u003eflips within its middle case\u003c\/strong\u003e to reveal either of its two sides — each with its own dial and its own bezel. This is not a simple dial reversal but a complete rotating module, which explains why the two sides have nothing in common.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003efirst side\u003c\/strong\u003e features a white lacquered dial with black Roman numerals, framed by a polished bezel with four visible golden screws. The aesthetic is graphic and crisp. The \u003cstrong\u003esecond side\u003c\/strong\u003e takes the exact opposite approach: a black dial with radiating facets, without a single hour marker, surrounded by a wide bezel on which only the Roman numerals XII, III, VI and IX are engraved in the gold. Day and evening on the same watch.\u003c\/p\u003e\n\u003cp\u003eInside is a \u003cstrong\u003eSeiko quartz movement, calibre 2N20\u003c\/strong\u003e, with two hands. No date and no seconds hand: nothing to disturb the design of either dial. Maintenance is limited to a battery change by any watchmaker. The movement of this example has been checked and the battery replaced.\u003c\/p\u003e\n\u003ch3\u003eThree points to note\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase reversible with two complete sides\u003c\/strong\u003e — each side has its own dial and bezel, giving two watches in a single case.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollaboration between Seiko and Hanae Mori\u003c\/strong\u003e — the manufacturing and movement of a Japanese manufacture under the design of a couturière, signed with the HM monogram.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo opposing aesthetics\u003c\/strong\u003e — white lacquer with Roman numerals on one side, black faceted without hour markers on the other.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy choose a vintage Seiko watch?\u003c\/h3\u003e\n\u003cp\u003eBuying a \u003cstrong\u003evintage Seiko watch\u003c\/strong\u003e rather than a new model means gaining access to a leading Japanese manufacture at a controlled budget. \u003cstrong\u003eVintage quartz watches\u003c\/strong\u003e from this period are also the easiest to maintain on the pre-owned market: a battery change is enough to get them running again.\u003c\/p\u003e\n\u003cp\u003eThis piece holds a distinct place among \u003cstrong\u003evintage men's and women's watches\u003c\/strong\u003e: the reversible case is a feature that very few brands have offered in serial production, and it makes it as much an \u003cstrong\u003eoriginal watch\u003c\/strong\u003e as a dress watch. Its 30mm size makes it equally wearable by both.\u003c\/p\u003e\n\u003cp\u003eLike all our \u003cstrong\u003epre-owned Seiko watches\u003c\/strong\u003e, this one has been opened and checked by our watchmakers: verification of the calibre, examination of the dials, hands, and case.

Each side has its own dial and its own bezel: it is therefore not a simple reversal of the dial, but a complete module that pivots. The mechanism should be handled gently, as with any watch with a movable case, and it is preferable to do so with the watch removed from the wrist.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the watch have one or two movements?\u003c\/strong\u003e\u003cbr\u003eOnly one. The two sides do not tell the time at the same time: it is the dial turned upward that is active. The case houses a single quartz movement Seiko, which explains the slimness of the whole and the simplicity of its maintenance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is a Seiko Hanae Mori?\u003c\/strong\u003e \u003cbr\u003eThis is a Seiko watch created in collaboration with Hanae Mori, a Japanese couturière and the first Asian designer admitted to the Chambre Syndicale de la Haute Couture in Paris.

Water resistance is never guaranteed on a vintage watch, and the reversible mechanism puts more strain on the case gaskets than a fixed construction. Avoid all contact with water, including when washing your hands.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat wrist size is this watch suitable for?\u003c\/strong\u003e\u003cbr\u003eWith a 30mm case and 42mm Lug-to-lug, it fits wrists from approximately 15 to 18.5cm.
