The Zenith DEFY Revival A3642 is a 37 mm stainless-steel reworking of the first DEFY, introduced in 1969. Its octagonal case, 14-sided bezel, brown-gradient dial and steel ladder bracelet give it a distinctive vintage-inspired profile, while an automatic Elite 670 movement supplies a stated minimum 50-hour power reserve. Zenith announced the 250-piece edition in 2022; its launch prices are historical, and current availability or resale value is not established here.
What the DEFY Revival A3642 is
Zenith announced the DEFY Revival A3642 on January 17, 2022, describing it as “a modern reinterpretation of the earliest DEFY model.” That original DEFY debuted in 1969. The reference covered here is 03.A3642.670/75.M3642—not every watch later sold under the DEFY Revival name. Zenith’s launch announcement and its technical specification sheet establish the history and details below.

What stands out in the design and specification
A compact, sharply shaped case
At 37 mm, the A3642 keeps to a relatively compact diameter while pairing an octagonal case with a 14-sided bezel. The geometry and ladder bracelet make it visually more distinctive than a conventional round steel sports watch. The listed diameter alone cannot establish how it wears: the cited specification sheet does not provide a lug-to-lug measurement or a hands-on fit assessment.
A restrained dial with a date
The brown gradient dial is complemented by faceted rhodium-plated markers and hands treated with Super-LumiNova SLN C1. Zenith lists central hours, minutes and seconds, with the date positioned at 4:30. The information is straightforward, though the offset date is a notable design choice rather than a conventional three-o’clock window.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Automatic movement and water-resistance rating
The automatic Elite 670 runs at 28,800 vibrations per hour (4 Hz), and Zenith states a minimum power reserve of 50 hours. The brand lists water resistance at 30 ATM. These are manufacturer specifications, not independent test results; the cited launch material does not detail test conditions or establish a practical use recommendation beyond the stated rating.
How it relates to the 1969 DEFY
The A3642 is presented by Zenith as a modern reinterpretation of the first DEFY model, rather than a claim that every construction detail of a vintage watch has been reproduced. The 1969 launch gives the design its historical reference point; the 2022 watch combines that revival framing with the specific materials, movement and functions in the specification table. The available official launch material does not provide a full, like-for-like technical comparison with an original A3642, so claims about exact vintage construction or performance would go beyond what it establishes.

Do not confuse it with the DEFY Revival Shadow
The DEFY Revival name also applies to other models. In particular, Zenith’s current product page identifies the DEFY Revival Shadow as a different 37 mm model in microblasted titanium. That material and current product-page status belong to the Shadow, not to the steel A3642 reviewed here. Zenith’s Shadow product page describes that separate watch.

The A3642 makes the strongest case for itself if you want a compact steel watch with unusually angular styling, a brown gradient dial and a bracelet that is integral to its vintage-inspired look. Its movement, date display and stated 30 ATM water resistance make it more than a design-only reissue on paper. Whether it is worth buying depends on the price and condition of the specific example available to you, as well as your preference for the 37 mm proportions and ladder bracelet.
