Citizen USA has added a fresh option to its aviation-ready lineup with the new Promaster Navihawk CA4664-60E, a pilot chronograph that leans into a smaller, more wearable size without sacrificing the tool-watch features the Navihawk name is known for. With a 40 mm stainless steel case and a sleek black sunray dial, this release is aimed at people who want a functional pilot watch that doesn’t dominate the wrist.
One of the biggest talking points here is the shift toward a more compact profile. Many earlier Navihawk models have pushed past 45 mm, which can feel oversized for everyday wear. The CA4664-60E takes a “midi-sized” approach at 40 mm, filling a long-standing gap in the market for pilot chronographs that still offer professional-style functionality while fitting a wider range of wrists.
Visually, the watch keeps things high-contrast and purpose-driven. The black sunray dial is paired with red accents for quick legibility. Around the dial, Citizen includes a bi-directional slide-rule bezel designed for classic aviation calculations such as fuel consumption and distance conversions, reinforcing the Navihawk’s pilot-tool identity rather than going purely for style.
Powering the watch is Citizen’s in-house B620 Eco-Drive movement, meaning it’s light-powered and designed to keep running without regular battery changes. From a full charge, it offers a quoted 270-day power reserve. The chronograph runs at 1/5-second resolution and measures up to 60 minutes, and there’s also a 24-hour sub-dial to help with day/night orientation—useful for travel and general cockpit-style time reading.
Durability specs are another area where the CA4664-60E clearly positions itself as a serious everyday sports watch. Citizen fits it with a scratch-resistant sapphire crystal with anti-reflective coating, and the watch is rated to 200 meters (20 bar) of water resistance. That makes it a practical option not just for daily wear, but also for activities like swimming and snorkeling—capability that many chronographs in this category don’t always match.
The CA4664-60E arrives at a moment when solar chronographs are getting plenty of attention across the watch world, with several new releases emphasizing color, vintage inspiration, and compact sizes. Citizen’s approach here is different: it focuses less on retro styling and more on a crisp, utilitarian instrument look, while also bringing stronger water resistance than many competing chronographs. The MSRP is set at $595, making it an accessible entry point for a sapphire-equipped, solar-powered pilot chronograph from a major brand.
For anyone comparing pilot-style chronographs right now, the Citizen Promaster Navihawk CA4664-60E stands out for three key reasons: the restrained 40 mm sizing, the Eco-Drive B620 movement with long reserve, and the combination of sapphire crystal plus 200 m water resistance. It’s a straightforward, modern tool watch built for real-world wear, not just the display box.
