The Citizen NH9133-01X, introduced in release coverage as Autumn Light, is a Thailand-only automatic limited to 300 pieces. Its case is 40mm across and 10.7mm thick, with pink-gold plating over stainless steel, a brown open-heart dial, sapphire crystal, a calf-leather strap and Citizen's Calibre 8229.
This is not a new movement story. It is an established open-heart platform given a very specific brown-and-warm-gold treatment. The open heart is not shy about being the point.
The 15-second answer
The Citizen NH9133-01X, known in release coverage as Autumn Light, is a Thailand-only 300-piece automatic with a 40mm pink-gold-plated steel case, brown open-heart dial, sapphire crystal and Calibre 8229. The design is the attraction. The 5-bar rating and regional availability are the limits.
What makes the NH9133-01X different
The dial does most of the work. Citizen's official images show a brown gradient that becomes darker toward the edge, with Roman numerals and slim hands in a warm matching tone. The open-heart aperture sits at six and exposes part of the movement, while the transparent case back gives the 8229 a second viewing window.
Citizen specifies pink-gold plating rather than a solid precious-metal case. That distinction matters. The visual effect is dressy and autumnal, but the underlying case remains stainless steel. A dark brown calf-leather strap completes the palette without adding another colour for the sake of it.
What changed
- Brown fumé-style open-heart dial with Roman numerals and warm-tone details.
- Pink-gold plating over the stainless-steel case, paired with brown calf leather.
- Thailand Limited Edition status, capped at 300 pieces and listed with dedicated packaging in release coverage.
What stayed the same
- Calibre 8229 remains the familiar automatic base rather than a new movement launch.
- The 40mm case format, sapphire crystal and 5-bar rating match Citizen's established NH913 open-heart family.
- The transparent case back keeps the movement visible from the rear.
Official product view
NH9133-01X Autumn Light
The official specification has one useful correction
Plus9Time's discovery caption listed the watch at 11.7mm thick. Citizen Thailand's live product page states 10.7mm, so this article follows the current manufacturer specification. The same page confirms the 40mm case width, sapphire glass, 5-bar water resistance and Calibre 8229.
That 10.7mm figure is a sensible proportion for a 40mm dress-leaning automatic. Citizen does not publish a lug-to-lug measurement or weight on the checked page, so there is no honest basis for a precise wrist-fit claim. The diameter should be manageable for many wrists, but the long Roman numerals and plated case make it visually louder than the measurement suggests.

What the Calibre 8229 does, and what Citizen does not state
Citizen identifies the movement as Calibre 8229 and labels it automatic. The product page does not publish accuracy, frequency or power reserve, so those figures are deliberately absent here. Numbers taken from a movement supplier or a related model may be plausible, but plausible is not the same as confirmed for this release page.
The visible balance and transparent back make the mechanism part of the design. That is useful if you want a mechanical watch to look mechanical from both sides. Buyers who prefer a cleaner dial will see the open-heart cut-out as a hole in an otherwise coherent brown design. Nobody needs a committee to settle that one.

The limited-edition presentation
Thailand availability and the UAE buying route
Citizen Thailand lists the NH9133-01X at ฿14,900 and calls it a Thailand Limited Edition of 300 pieces. That is a Thai-market price and allocation. It is not a converted UAE retail price, not evidence of local warranty coverage and not confirmation that the model will receive a wider release.
WristBear did not have an exact NH9133-01X product record when checked on 27 September 2026. The broader Citizen collection did have 10 active products with positive inventory, including current automatic options. That makes the maintained Citizen collection a useful route without pretending this exact watch is waiting on a Dubai shelf.
WristBear verdict
The NH9133-01X makes sense for somebody who wants a conventional 40mm automatic dressed up with a brown fumé-style dial, Roman numerals and pink-gold plating. Sapphire crystal is a welcome practical choice, and the 10.7mm official thickness keeps the case from becoming needlessly bulky.
The trade-offs are just as clear. It is region-limited, only rated to 5 bar and visually committed to the open-heart treatment. Choose it if that warm brown-and-gold execution is exactly the point. Skip it if you want a quieter dial, stronger water resistance or a model with confirmed UAE availability.
Because the exact release is not listed at WristBear, the honest next step is to browse the current Citizen watches at WristBear and compare the automatic models that are actually available.
