Terra Force AW1890-51X Citizen's solar field watch gets a bracelet

What is new about the Terra Force AW1890-51X?

Terra Force has been Citizen's name for chunky solar chronographs and outdoor pieces. The AW1890 is something simpler: a three-hand field watch with a date. Citizen's US site lists the AW1890-51X as launched on 28 January 2026, alongside two siblings. The AW1890-19B has a white linen-texture dial on brown leather, and the AW1890-01A has a grey grid-texture dial on a grey fabric NATO. This one pairs a green dial with a matching steel bracelet.

The dial is the most interesting part. It has a fine grid texture, large white Arabic numerals, a small inner 24-hour scale and a curved minute ring with luminous markers. The hour and minute hands are partly skeletonised, with lume filling only their outer sections. The date sits at 6 o'clock, so it doesn't interrupt the numerals at 3. The crown is large and deeply knurled, the kind you can turn with cold fingers.

How big is it, and how will it wear?

Citizen quotes a case width of 41.2 mm and a lug width of 22 mm. It does not publish thickness or lug-to-lug length, so we can't tell you exactly how it will sit. The case has an angular profile and a broad polished bezel, and the bracelet is a three-link design that tapers very little. Together they make the watch look solid rather than delicate.

For a field watch, 41.2 mm is on the generous side. Traditional military pieces were often 36 to 38 mm. If you have a slim wrist, the 40 mm AW1870 and AW1877 military models Citizen introduced in early 2026 may suit you better. The bracelet closes with a fold-over clasp with push buttons, and the 22 mm lugs mean a NATO or leather strap is easy to find if you want a lighter, more traditional look.

What movement does it use, and how accurate is it?

Inside is the Eco-Drive calibre J810. It is a light-powered quartz movement: a solar cell under the dial charges a rechargeable cell, so there is no battery to replace. Citizen says the J810 is accurate to within plus or minus 15 seconds per month at normal temperatures. Citizen does not publish a power reserve figure on the AW1890 page itself, but Eco-Drive watches are designed to keep running for months on a full charge.

The J810 is a workhorse calibre that has run cheaper Citizen models for years. It has hacking seconds and overcharge protection. It doesn't have a power reserve indicator. You get a two-second ticking seconds hand as the low-charge warning instead. There is no radio control and no perpetual calendar, so you will set the date by hand at the end of short months.

How well is it built?

The case and bracelet are stainless steel, and Citizen rates water resistance at 100 m (10 bar). That is enough for swimming and snorkelling, though not for diving. The crystal is mineral glass, which Citizen describes as impact and shatter resistant. It will scratch more easily than sapphire, and at the RRP sapphire is not unusual among rivals.

Citizen covers the watch with a five-year warranty. That is long for this price and reflects how little servicing a solar quartz watch needs. The textured dial and skeletonised hands suggest Citizen has spent its budget on the parts you look at, rather than on the crystal.

Is it good value against its rivals?

UK authorised retailer Michael Jones Jeweller lists the AW1890-51X at £249, and Striacroft lists the leather-strap AW1890-19B at £229. Citizen UK's own site was not reachable when we checked, so treat those as UK retail prices rather than an official RRP.

The closest rival is the Timex Expedition North Field Post Solar 41mm. Timex UK sells it from £160 on leather and up to £190 on fabric. It also runs on solar power, with a similar size and a similar brief, but it ships on straps rather than a steel bracelet. Against it, the Citizen asks around £60 to £90 more and gives you a full bracelet, a five-year warranty and a much longer track record for its solar movement.

Inside Citizen's own range, older Eco-Drive field watches on straps often sell for less. The premium here is for the new case, the textured dial and the bracelet.

What is the catch?

There are three. First, the crystal is mineral, not sapphire, so expect fine scratches over time. Second, Citizen does not publish thickness or lug-to-lug, so you will need to try one on or check a retailer's measurements before buying. Third, the AW1890 is too new for a body of owner feedback, so long-term reports on the bracelet and lume are not yet available. The J810 calibre itself has a long history in other Citizen models.

If you want a field watch you can set once and largely ignore, those are modest compromises. If you want a slim, vintage-sized watch, look at the 40 mm models instead.

“A field watch for people who would rather never think about their watch's battery again.”
