A limited collaboration model from Citizen Collection TSUYOSA that has become a hot topic overseas.NJ0157-81Lhas appeared.
A collaboration with French artist Romaric Andre's watch design project "seconde/seconde/" (limited to 3,600 pieces worldwide). It is a mechanical watch that is more fun, more artistic, and has a more neo-Japanese personality.
The unique dial devised by Mr. André, including the pixel-shaped minute hand inspired by a Japanese sword and the index cut into two, has an overwhelming presence on the blue sunray dial.

The clasp of the band is engraved with a sword cut mark, and the playful detail shines through. The back cover contains a message "seconde/seconde/" related to the design concept. The limited edition box was also supervised by Mr. Andre, and the completeness of the total coordination is impressive.

■ What is seconde/seconde/?

seconde/seconde/ is a French watch design project led by Romaric Andre. His approach of ``cutting,'' ``disassembling,'' and ``reconstructing'' existing clock hands and indexes has attracted attention from watch collectors and contemporary art fans around the world. The concept of this collaboration is "Being smaller has never stopped Minutes from slicing Hours into pieces" - the philosophy of the minute hand slicing the hour hand perfectly overlaps with the Japanese sword motif.

The message is engraved on the back cover, and the piece is completed not only from the front but also from the back. The NJ0157-81L is a model that effortlessly crosses the line from "wearing a watch" to "wearing art."

■ Dial board with Japanese sword design

The main feature of the dial is the minute hand, which reproduces the blade of a Japanese sword using pixel-like dots. The angular digital touch, which is different from regular Seward Hands, completely changes the world view of watches. The index has a unique design with the top section cut out to look like it has been slashed, and it is impressive that the entire dial is completed as a single work, with the top at 12 o'clock.

The blue sunray dial is the star of this design. The sunray finish changes shades depending on how the light hits it, creating a look that stands out both outdoors in broad daylight and indoors under fluorescent lights.

■ Playfulness in every detail

A sword cut mark is engraved on the three-fold push-type clasp of the band. Mr. Andre's particular approach is to take care of the parts that are usually hidden by the sleeves. The playfulness of adults shines, which can only be enjoyed by those who notice it.

Additionally, the Cal.8210 rotor can be seen through the see-through back, allowing you to enjoy it as art from the back. Even the limited edition box is supervised by Mr. Andre himself, and the fact that it is designed to be an experience from the moment you open the box really stimulates the collector's heart.

■ Cal.8210's reliability

The installed movement is Citizen's in-house Cal.8210. Available in both automatic and manual winding, the watch has a power reserve of approximately 42 hours. Although it is a mechanical range with an accuracy of -20 to +40 seconds per day, it also has a second hand stop function (hacking) that allows you to set the time accurately.

The configuration of 21 jewels and 21,600 vibrations is a solid finish for this price range. The pleasure of watching the rotor's movement through the see-through back is the real thrill of a mechanical watch. The feeling of winding up the spring and keeping time ticking every time you wear it every day creates a sense of attachment that quartz doesn't have.

■ 40mm case “just right”

The case diameter is 40mm and the thickness is 11.7mm. Although it is a modest size in the modern large diameter trend, it fits perfectly on the wrist of many Japanese people. Weighing 138g, it is a full metal shoe with an exquisite balance of comfort and presence. The band adjustment range is wide from 145 to 208 mm.

Sapphire glass boasts a hardness that is second only to diamond, greatly reducing scratches caused by daily wear. There is a sense of security that the beauty of the blue sunray dial will be maintained for a long time.

■ Rarity: “Limited to 3,600 pieces worldwide”

Unnumbered model, limited to 3,600 pieces worldwide. Although there is no individuality like numbering, the global quantity of 3,600 pieces is by no means a large amount that can be afforded. Considering the domestic quota, the best time to buy is when you can find it.

It has already become a hot topic in various places as a new product to be released in February 2026, and this model, which combines TSUYOSA's popularity and limited edition, is one that we recommend you buy before it becomes difficult to obtain.
