Citizen Vietnam has recently refreshed its 2026 catalog, introducing two brand-new collections. These include a duo of black-cased Eco-Drive chronographs (AT2137-50) and a set of four mechanical models (NJ0240/NJ0242). The new timepieces feature H500 solar and 8210 automatic calibres, with case sizes ranging from 40 mm to 43 mm and water resistance rated up to 10 bar.
New Sports Chronographs
The February 2026 release kicks off with the AT2137-50E and AT2137-50F, both sporty chronographs constructed from black-cased stainless steel. These watches are driven by the Citizen H500 Eco-Drive calibre, allowing for a standard 1-second chronograph function with a capacity of 60 minutes. They also include a 24-hour sub-dial and a date display positioned at 4 o’clock.
With a case width of 43 mm and a slim profile of just 11.2 mm, this watch could serve as a daily companion for those in search of a lower-profile chronograph. The main difference between the two models lies in their design: the AT2137-50E showcases gold-plated hands and indices for a striking contrast, while the AT2137-50F features red accents on the dial for a classic racing vibe. Both models come equipped with a tachymeter scale on the inner bezel and offer water resistance up to 100 meters.
Elegant Mechanical Models
The latter part of the launch features four mechanical models that take on a more classic dress watch appearance, confirmed by the inclusion of Roman numerals at the 12 and 6 o’clock marks. These timepieces are powered by the 8210 automatic calibre, a movement with 21 jewels that can be seen through an exhibition case back. It runs at 21,600 vibrations per hour and has a power reserve of around 40 to 43 hours.
These watches boast refined dial finishes and case materials. The NJ0240-55A (white dial), NJ0240-55E (black dial), and NJ0240-55X (salmon dial) all feature brushed and polished stainless steel, complemented by matching multi-link bracelets. The NJ0242-50E stands out as the flagship of the series, showcasing a full gold-toned PVD coating on the case and bracelet, along with a matte black dial. Each of the four models maintains a diameter of 40 mm and a thickness of 11.6 mm.
