[Limited to 1,200 pieces worldwide] Citizen Series Eight NB6086-54E｜Forged carbon x Cal.9051 Small diameter and thin, fearless black dial with a limited edition “special feeling”

Citizen Series Eight is a world limited model released in March 2026.NB6086-54Ehas been added. This is a rare piece, limited to 1,200 pieces worldwide, and is a special edition with a forged carbon dial.
The equipped Cal.9051 is a series eight thin mechanical movement that boasts high accuracy with a difference of -10 to +20 seconds per day. While taking advantage of Series Eight's design concept of ``separate structure'', we pursue a small diameter and thin form that reduces the case diameter and thickness to fit comfortably on your wrist. The sharp edges of the five-part case, each thoroughly polished, contrast with the random patterns of the forged carbon, creating a fearless finish.

Of the limited edition of 1,200 pieces, each dial has a different pattern - the joy of wearing such a unique watch on your wrist cannot be replaced by any other model.

When you put it on your arm, the forged carbon's fearlessness stands out.

A piece that has a unique expression even when lined up or viewed.

Forged carbon x gray gold plating—a contrast of fearless beauty.

The polished finish of the 5-part case—class is in the details.

■ The value of “one-of-a-kind” forged carbon

The forged carbon used for the dial of the NB6086-54E is a material made by cutting carbon fibers into short lengths and randomly mixing them together. It is a lightweight and strong material that is also used in aircraft and high-performance sports cars, and the patterns created from the randomness during molding are all different. In other words, all of the 1,200 pieces limited to around the world are unique in terms of the expression on the dial. The greatest value of this material is its ``unique individuality'' that cannot be obtained with mass-produced products.

The gray and yellow gold plating creates an exquisite contrast on the black forged carbon. This finish, which coexists with a sense of solidity and elegance, has a deep feel that can be used as both a dress watch and a sporty watch.

■ “Series 8 accuracy level” indicated by Cal.9051

The equipped Cal.9051 is a thin, high-precision mechanical movement used in the Series Eight 880 line. The accuracy of -10 to +20 seconds per day is an outstanding level for a mechanical watch. The precise structure of 24 stones continues to create a stable rhythm through daily wear. The power reserve at maximum winding is approximately 42 hours, and it is compatible with both automatic and manual winding.

The heartbeat of the movement visible through the see-through back is one of the greatest joys of owning a mechanical watch. Another highlight of this model is the see-through back that allows you to directly see the delicate movement of Cal.9051.

■ “Small diameter and thin arm fit” created by separate structure

The core of Series Eight's design lies in its "separate structure." The structure that separates the case and movement allows each part to be optimized independently. The NB6086-54E takes advantage of this separate structure and has a small-diameter, thin design that reduces the case diameter. The size of 47mm long x 42.5mm wide x 11mm thick makes it one of the most comfortable in the series eight.

Each of the five parts that make up the case has been thoroughly polished, and the sharp edges create beautiful shadows when reflecting light. The carefulness of this finish asserts its status as a luxury watch on your wrist.

■ “Compatible with modern life” with class 2 magnetic resistance

The Type 2 magnetic resistance that Series Eight comes standard with is designed to maintain time accuracy even in the face of magnetic fields generated by devices we come in contact with on a daily basis, such as smartphones and tablets. The design's ability to maintain performance in most cases even when placed as close as 1 cm to devices that generate magnetic fields is a practical feature that fits modern lifestyles. The sapphire glass clarity coating and luminous hands and indexes ensure visibility and practicality.

■ Buyer's comment

When I first picked up the NB6086-54E, I couldn't help but take a closer look at the forged carbon pattern as it had more depth than I expected. The fact that no two pieces have the same pattern definitely increases the joy of owning it, both as a collector and as a regular user. Cal.9051's thinness and high precision capabilities are perfect for Series Eight. There are only 1,200 pieces in the world, which is by no means abundant, so if you're interested, you should get your hands on one as soon as possible.
