Japan's renowned watchmaker "SEIKO" has a history of collaborating with various ACG (Anime, Comics, Games) IPs to release stylish watches, consistently earning high praise from fans.
They've just announced a fresh collaboration with Nisio Isin's novel series, "Monogatari Series," dropping two limited-edition watches featuring fan-favorite characters - Mayoi Hachikuji and Shinobu Oshino. Only 2,000 units of each will be available, priced at 54,780 JPY. Pre-orders are open now on the PREMICO official website, with an anticipated release in mid-August 2025.

This marks the first time Nisio Isin's supernatural youth novel series, "Monogatari Series," has teamed up with SEIKO. The chosen collaboration characters are none other than the beloved Mayoi Hachikuji and Shinobu Oshino.
Both watches are strictly limited to 2,000 pieces each and come with an exclusive acrylic display stand featuring newly drawn illustrations. Talk about a must-have collectible that's both stylish and practical!

▼ Mayoi Hachikuji Model
The enigmatic "snail" apparition, Mayoi Hachikuji, who appears as a fifth-grader with a giant backpack in an empty park, inspires this watch's clean white dial. Her iconic pink backpack, hairband, ribbons, and even a snail motif are subtly integrated into the design. Look closely, and you'll spot park playground equipment cleverly worked into the outer bezel's markers.


▼ Shinobu Oshino Model
Shinobu Oshino, the blonde vampire girl in her "final form," gets a striking yellow gradient dial. Her beloved donuts and the demonic sword "Kokorowatari" subtly emerge on the watch face, while the 1 and 11 o'clock markers are cleverly shaped like vampire fangs. Plus, Shinobu's true name is engraved on the bezel!


The case back features a laser-engraved illustration by anime ED animator Hajime Ueda, along with the watch's unique limited edition number.

Both models come in specially designed collector's boxes, each incorporating unique character-themed elements.

Each watch also includes an acrylic character display stand (approx. 31x25cm) featuring exclusive, newly drawn collaboration artwork, perfect for showcasing your timepiece alongside its character.
