AVI-8 lists it at $450 USD. Fratello reviewer Thomas Van Straaten found it comfortable and well finished for the price, but considered its assertive blacked-out look best suited to casual wear.
What is the AVI-8 CVRT 3775A?
The Night Shadow, reference AV-4141-01, is a collaboration between AVI-8 and Worn & Wound Creative Services. It takes aviation and military-inspired cues into a restrained field/tool-watch design rather than presenting itself as a pure pilot’s watch. Van Straaten’s November 24, 2025 Fratello review describes it as an unusually restrained design for AVI-8, a brand associated with detailed aviation-themed watches. Fratello’s hands-on review
The black Night Shadow combines a dark dial and coated steel case with red accents. Its proportions are on the compact side for a contemporary tool watch, while the styling is more specifically tactical than the dimensions alone suggest.

How does the CVRT 3775A wear?
Van Straaten reports that the short 46 mm lug-to-lug span and the case’s shape give it a comfortable stance, with the case wrapping around the forearm. He found the overall wearing experience notably pleasant. These are one reviewer’s observations, not a guarantee of fit on every wrist.
Matthew Catellier likewise reported a good fit on his 6.5-inch wrist in a March 25, 2026 WatchReviewBlog review. He noted the 37.75 mm diameter, 11 mm thickness and 46 mm lug-to-lug measurement, alongside the applied luminous numerals, red details, subtle black date wheel and 4 o’clock crown. His wrist fit is an individual report, not a sizing rule. WatchReviewBlog’s review

The case is not visually uniform: Fratello describes a blacked-out knurled bezel frame, brushed top surfaces, polished chamfers and bead-blasted flanks. The combination adds contrast without turning the watch into a bright or dressy design.
Dial, legibility and the minute track
The matte black dial uses applied luminous indexes and numerals, with a date window at 4:30. Fratello found the display easy to read. The date wheel is also black, an understated detail Catellier called out in his review.

Van Straaten points out a small design mismatch: the minute track is divided into fifths, while the Miyota movement beats at 4 Hz, or four times per second. He considers the mismatch of no practical consequence for most wearers; it is a detail for those who pay close attention to the relationship between the dial markings and movement.
Movement: Miyota 9015
The automatic Miyota 9015 can also be wound by hand, and its seconds hand stops when the crown is pulled to the setting position, making synchronization easier. AVI-8’s movement guide and Fratello list a 28,800-vibration-per-hour rate and 42-hour power reserve; Fratello also reports 24 jewels. Those figures describe the movement specifications, not a measured accuracy result for this particular watch.

Straps and water resistance
AVI-8 includes black rubber and black nylon straps. Fratello describes the rubber strap as curved and integrated at the case, with quick-release pins. AVI-8 calls it a 24 mm strap, while Fratello reports a 20 mm width at the case and 24 mm at the lug tips. Because of that geometry, the listed 24 mm figure alone does not establish that a generic replacement strap will fit.
The official water-resistance rating is 10 ATM. That rating is not, by itself, a specific activity recommendation; the available product information does not establish a use-specific swimming or diving promise.

Is the AVI-8 CVRT 3775A worth $450?
AVI-8 lists the Night Shadow for $450 USD. Fratello’s November 2025 article also quoted $450 USD for its publication context, alongside €398.95 and £421 at that time; those euro and pound figures are dated prices, not current currency conversions or confirmed local prices.
At the listed US price, the case dimensions, sapphire crystal, automatic Miyota movement and two included straps form a substantial specification set. Van Straaten judged the fit-and-finish compelling for the listed price. The main trade-off in his assessment is stylistic: he sees the tactical look as most natural with casual clothing and occasions, rather than as an especially versatile everyday design. That is a subjective judgment from one reviewer, not a consensus.
AVI-8 states that its two-year international warranty requires registration, with the 24-month period starting from purchase. The product page also currently states free shipping, shipment within three business days unless otherwise indicated, and returns within 30 days of delivery; these purchase terms and the listed price may change.
