Citizen launches Promaster Air NK0040-58P with champagne dial and Super Titanium case

Citizen has introduced a new champagne-dial variant of its Promaster Air mechanical watch in the US and UK. The NK0040-58P joins the black and blue versions, the latter of which arrived in September.

Design Details

The watch is built around a 40mm case made from Super Titanium, which is Citizen’s proprietary titanium alloy treated for extra surface hardness. This material makes the watch significantly lighter on the wrist than standard stainless steel, while remaining highly resistant to the scratches and scuffs of daily wear. The watch comes on a matching titanium bracelet that secures with a standard fold-over clasp and hidden push buttons.

Because it is categorized as a pilot’s watch, the Promaster Air includes a functional outer slide-rule bezel. While most people rely on digital instruments or smartwatches today, the slide-rule is a traditional analog tool historically used by pilots for calculating variables like fuel consumption, speed, and flight distance.

The dial itself is straightforward, featuring applied metal indices, a standard three-hand layout, a date window, and a few red accents to help with overall legibility. The face is covered by a flat sapphire crystal equipped with an anti-reflective coating to cut down on glare.

Internally, the watch runs on Citizen’s Caliber 8310 automatic movement. It is a strictly mechanical caliber, meaning it doesn’t use a battery. Instead, an internal oscillating weight winds the mainspring automatically as you move your arm throughout the day.

The movement features a 60-hour power reserve and includes a hacking function, which lets you stop the second hand completely when setting the time to ensure precise synchronization.

For durability, the Promaster Air carries a WR200 water resistance rating (200 meters or 666 feet), making it suitable for swimming, showering, and snorkeling despite its aviation-focused design.

Pricing and Availability

The Promaster Air NK0040-58P is available to purchase now directly through Citizen’s US and UK websites. It is priced at $895.00 in the United States and £599.00 in the United Kingdom.
