Citizen Nighthawk Eco-Drive CA0897-04H: A breath of fresh air for pilot watches.
Citizen introduces the Nighthawk CA0897-04H, featuring a tactical grey design and nylon strap. This product uses an Eco-Drive light-powered movement, is water-resistant to 200m, and includes a chronograph function.
Citizen has officially added a new variant to its renowned Nighthawk line with the model number CA0897-04H. This watch offers a "tactical" (military style) look with a dominant gray color scheme, a complete departure from the traditional black IP-plated versions commonly found in the Promaster collection.
The design is inspired by the cockpit of a military aircraft.
The Nighthawk line, originally part of the Citizen Promaster collection since the late 1980s, is renowned for its design philosophy borrowed from the cockpit control panels of military helicopters. The CA0897-04H version continues this legacy but changes its aesthetic approach.
Instead of a black-plated stainless steel case, the CA0897-04H features a 42mm steel case in a matte gray tone. Combined with a gray nylon strap instead of a metal one, this creates a more minimalist and rugged look, closer to the style of specialized field watches.

Eco-Drive technology and Calibre B612 movement
At the heart of the Citizen CA0897-04H is the Calibre B612 movement, utilizing proprietary Eco-Drive technology. The strength of this technology lies in its ability to convert any light source into energy for operation, meaning users will never need to replace the battery throughout the product's lifespan.
In terms of functionality, this movement offers a chronograph with 1/5-second accuracy (up to 60 minutes), 12/24-hour time display, and a date window at the 3 o'clock position. The watch retains the rigorous standards of the Promaster line, such as the internal tachymeter, screw-down crown, and 200-meter water resistance.

Differences compared to previous versions
Compared to the existing CA0890-54H model, which uses the same movement but comes with a metal strap, the CA0897-04H version offers a lighter and more flexible feel thanks to its nylon strap. The gray tones on the dial and sub-dials provide good contrast, aiding in quick time reading in various lighting conditions.

Although the official price for the nylon strap version has not been confirmed, based on the listed price of around $350-$375 for the metal strap version, the CA0897-04H is predicted to be priced similarly or slightly lower, making it an attractive option in the mid-range pilot watch segment.
