Citizen has refreshed its Vietnam watch catalog for 2026 with six new additions that cover two popular tastes: modern, sporty solar chronographs and classic automatic mechanical pieces. The update includes two Eco-Drive chronographs in a stealthy black-cased design (AT2137-50 series) plus four automatic watches powered by Citizen’s 8210 calibre (NJ0240/NJ0242 series). Across the lineup, all six models offer water resistance up to 10 bar (100 meters), making them practical options for everyday wear.
Two new Eco-Drive chronographs: AT2137-50E and AT2137-50F
Leading the release are the Citizen AT2137-50E and AT2137-50F, a pair of sports chronographs built with black-cased stainless steel for a bold, modern look. Both watches run on the Citizen H500 Eco-Drive movement, which uses light to keep the watch powered—ideal for buyers who want the convenience of a solar-powered watch without regular battery changes.
Functionally, these chronographs are set up for daily utility. You get a 1-second chronograph with a 60-minute totalizer, a 24-hour sub-dial, and a date window positioned at 4 o’clock. Citizen also includes a tachymeter scale on the inner bezel, leaning into the classic motorsport-inspired chronograph style.
Despite the larger 43 mm case diameter, the watches keep a relatively slim profile at about 11.2 mm thick, which could appeal to anyone who likes the presence of a bigger case but doesn’t want an overly bulky chronograph on the wrist.
The big difference between the two references comes down to styling:
– The AT2137-50E uses gold-plated hands and indices for a sharper, high-contrast finish against the darker design.
– The AT2137-50F goes in a sportier direction with red accents, giving it a more traditional “racing” color theme.
Four new automatic models with 8210 calibre: NJ0240 and NJ0242 series
The second part of Citizen’s 2026 Vietnam catalog update shifts from sporty to classic, introducing four mechanical automatic watches that emphasize a more traditional dress-watch silhouette. A key design cue is the use of Roman numerals at the 12 and 6 o’clock positions, adding a formal touch while keeping the overall look clean and versatile.
Inside these watches is Citizen’s 8210 automatic calibre, a 21-jewel movement visible through an exhibition case back. It runs at 21,600 vibrations per hour and provides an approximate power reserve of 40 to 43 hours—solid everyday specs for an automatic watch in this category.
All four automatic models share the same case sizing, positioned for broad wrist appeal:
– 40 mm case diameter
– 11.6 mm thickness
– Water resistance up to 10 bar (100 meters)
Three of the models come in stainless steel with coordinated multi-link bracelets and a mix of dial colors:
– NJ0240-55A with a white dial
– NJ0240-55E with a black dial
– NJ0240-55X with a salmon dial
Sitting at the top of this mini-collection is the NJ0242-50E, which stands out with a full gold-toned PVD finish across the case and bracelet, paired with a matte black dial for a more striking, dress-forward look.
A well-rounded Citizen 2026 Vietnam lineup for solar and automatic watch fans
With these six new releases, Citizen is clearly aiming to cover two major buyer preferences in one catalog update: low-maintenance Eco-Drive chronographs for sporty everyday use, and classic automatic watches with exhibition case backs for people who enjoy traditional mechanics. Add in the consistent 100-meter water resistance across the board, and this lineup shapes up as a practical, style-focused refresh for 2026.
