The Citizen Promaster NK0040-58P takes an instrument-led pilot watch and warms it up. A champagne dial with applied indices and red accents sits beneath an outer slide-rule bezel, set in a 40mm silver-tone Super Titanium case. The result is a watch with genuine aviation credentials that reads far dressier than the usual black or blue pilot dial, and sits just as comfortably with a shirt as it does with a weekend jacket.
Inside is Caliber 8314, a mechanical automatic movement with 21 jewels running at 21,600 vibrations per hour. It winds itself from the motion of your wrist and holds approximately 60 hours of power reserve when fully wound, so it is still running after a day or two off the wrist. A date display keeps the everyday information you need on the dial.
The 40mm Super Titanium case stands 13.3mm tall and is protected by sapphire glass, with shock protection and 200-metre water resistance specified by Citizen. The matching Super Titanium bracelet closes with a fold-over clasp with hidden double push-button release for a clean, uninterrupted line around the wrist — and holds securely through travel, swimming and daily wear.

Why You'll Love It
- A pilot watch you can wear to dinner: The champagne dial gives this Promaster a softer, warmer presence than the usual aviation palette, while applied indices and red accents keep the instrument character intact.
- Mechanical character with a weekend-proof reserve: Caliber 8314 winds itself from your wrist movement and holds approximately 60 hours of running time, so it is still going after a day or two in the drawer.
- A bezel with a job to do: The outer slide-rule bezel carries working calculation scales drawn from Citizen's pilot-watch heritage, not a decorative ring.
- Super Titanium comfort at 40mm: Case, bezel and bracelet are all Super Titanium, giving the watch an easy, unobtrusive feel across a full day — and a hidden push-button clasp that keeps the bracelet line clean.
- Built for real use: Sapphire glass, shock protection and 200-metre water resistance mean it handles travel, swimming and everyday knocks without special care.

Frequently Asked Questions
Does the NK0040-58P need a battery?
No. It is a mechanical automatic watch powered by Caliber 8314, which winds itself from the natural movement of your wrist. There is no battery and no light charging involved. If it has been sitting unworn, a few turns of the crown or some wrist movement will start it again.
How long will it run if I take it off?
Citizen specifies approximately 60 hours of power reserve from a full wind. In practice you can leave it off overnight or across a weekend and expect to find it still running, though you may need to check the time and date after a longer rest.
What is the slide-rule bezel used for?
A slide rule is the classic pilot-watch calculation tool. Its outer scales are used to work out conversions and flight-related sums such as distance and fuel figures. On this model it is a genuine functional scale rather than a decorative ring, in keeping with Citizen's Promaster aviation line.
Is this a gold-tone watch?
No. The champagne colour is the dial. The case, bezel and bracelet are silver-tone Super Titanium, so the warm tone comes from the dial and its red accents rather than from the metal — which is what gives the watch its dressier look without changing its sports-watch construction.
Can I swim with the NK0040-58P?
Yes. Citizen specifies 200 metres (20 BAR) of water resistance, which covers swimming and general water recreation when the watch is used according to Citizen's instructions. Avoid operating the crown while the watch is wet.
Will the 40mm case suit a slimmer wrist?
At 40mm across, this is a notably compact size for a pilot watch with a slide-rule bezel, and the Super Titanium construction keeps it comfortable. The case does stand 13.3mm tall, so it wears as a proper sports watch rather than a slim dress piece. We recommend trying it on in any City Chain store.
Does it show the date?
Yes, there is a date display on the dial. As with any mechanical watch, the date will need adjusting if the watch has stopped, and at the end of any month shorter than 31 days.
Can the Super Titanium bracelet be adjusted?
Yes. The bracelet can be sized by removing or adding links where compatible. City Chain Singapore offers in-store bracelet adjustment — please bring your warranty book with you.
What warranty is included?
This model comes with a 3-year warranty when purchased from City Chain Singapore, an authorised Citizen retailer. Keep your warranty documentation and proof of purchase for any future servicing.
