Its 47 mm lug-to-lug length, 13.3 mm total thickness and stated 200 m water resistance make it a compact-to-mid-sized proposition on paper; the key buyer checks are wrist fit, current landed cost and the way its fixed 24-hour bezel suits your travel routine. Nezumi lists reference AA3.102 as assembled in Germany. The figures below are published specifications, not independent measurements.
What changed in the Aviera GMT V3?
V3 keeps the 40 mm case diameter and 47 mm lug-to-lug length, but Nezumi’s regular-production AA3.102 pairs that case with a 39 mm bezel. Fratello’s July 2025 hands-on report describes a thinner metal case and a taller, vintage-shaped sapphire crystal, with the total height remaining 13.3 mm. The official listing breaks that height into an 11.4 mm case and 1.9 mm crystal; Fratello reports 11.35 mm and 1.95 mm respectively. The component figures differ slightly by source, while both give 13.3 mm overall.

The smaller bezel relative to the case and the changed case-to-crystal proportions are the clearest documented V3 revisions. The available descriptions do not establish how those changes affect comfort or perceived size on a particular wrist, so the dimensions are more useful as a screening guide than as a fit guarantee.

V3 references
Fratello’s July 2025 report identifies three versions: AA3.102 as the regular-production model, AA3.133 in black DLC with a green GMT scale, and AA3.302 as a cream full-lume edition. The report says the latter two were limited to 300 pieces each. Confirm the current status and availability of any reference before buying.

How does the GMT hand work?
The Miyota 9075 is a flyer GMT: the local 12-hour hand adjusts independently, while the separate 24-hour hand continues to indicate a second time zone against the fixed 24-hour bezel. This is useful when crossing time zones because you can move local time in one-hour increments without resetting the minute hand and the displayed reference time.
- Set the 24-hour GMT hand to your chosen reference time using the crown’s time-setting function.
- When you arrive in a different time zone, adjust the local 12-hour hand independently to local time.
- Read the reference time from the 24-hour hand against the fixed 24-hour bezel.
The bezel is fixed, so it cannot be rotated to temporarily offset the GMT reading. If you prefer a rotating bezel as a quick elapsed-time or time-zone aid, that distinction is worth weighing before purchase. Fratello describes the 9075 as automatic, manually windable and hackable, with a 28,800-vph beat rate, 24 jewels and a 42-hour power reserve.

Fit and thickness
A 40 mm diameter and 47 mm lug-to-lug length provide a useful basis for comparing the Aviera with watches you already wear. Lug-to-lug is especially relevant to how far the case may span across the wrist, but wrist shape, strap or bracelet choice and the raised domed crystal all affect how a watch wears. Try it on if possible, or compare the dimensions with a watch whose fit you know. The 13.3 mm figure includes the crystal, so it should not be compared directly with a case-only thickness figure.

Bracelet, strap and weight
The official listing gives a 20 mm lug width. Fratello describes bracelet, leather, canvas and rubber configurations, while WatchReport notes quick-release pins and reports weights of 150 g on bracelet and 92 g on strap. Those weights are the reviewer’s reported specifications, not independently verified measurements here. For an aftermarket strap, confirm not only the 20 mm width but also end fit and spring-bar arrangement.
Price and stock
Prices reported in 2025 are dated reference points, not current quotes. Fratello’s July 7, 2025 article reported launch prices of €636 excluding taxes for AA3.102 on the Colin 2.2 bracelet, €589 excluding taxes on Hunt leather or Juno canvas, and €576 excluding taxes for Malta rubber-strap configurations. WatchReport’s September 13, 2025 review said pricing started at $673. The sources give different currencies and configuration contexts, so these figures are not a direct like-for-like comparison.

Nezumi’s official listing was observed out of stock with a waitlist. It also stated free worldwide shipping, a two-year warranty and destination-specific tax and duty treatment; for US orders, it displayed an estimate that duties or tariffs may typically be around 15% of the watch value. Availability, checkout totals and import charges can change and vary by destination. Check the live product page and your local import rules before treating any listed price as the amount you will pay.
How to compare it with another GMT
- Check whether the alternative has a flyer or caller GMT, and whether its bezel is fixed or rotating.
- Compare case diameter, lug-to-lug length and total thickness on the same basis.
- Review crystal shape, case material, crown construction and stated water resistance.
- Compare movement frequency and power reserve, then consider how those specs fit your use.
- Include the actual bracelet or strap configuration, taxes, delivery and destination charges in the price comparison.
- Verify live stock and warranty terms for your region rather than relying on dated launch coverage.
Who is the Aviera GMT V3 for?
The strongest case for the Aviera is a buyer who wants a mechanical GMT with independently adjustable local time, a fixed 24-hour reference scale and dimensions that sit below many larger travel watches. The 9075 provides the travel-oriented hand-setting function; the 20 mm lug width and reported range of strap and bracelet choices give configuration flexibility.

It is less straightforward for someone who requires a rotating bezel, needs to know how the watch fits without trying it on, or is deciding on value from a current price that has not been confirmed. In those cases, verify the exact reference, configuration and landed cost first. Fratello’s V3 article discloses that it is a partnership post; WatchReport published a separate review in September 2025.
