The Citizen NB6044-54L is a limited edition Promaster Sky built in tribute to the Blue Angels, the U.S. Navy's flight demonstration squadron. The squadron's colours run through the whole watch: a deep blue 24-hour scale against a yellow slide-rule scale, on a navy dial with luminous silver-tone hands and Arabic numerals at 6 and 12.
This is a genuine aviation instrument. A slide-rule scale handles flying distance and navigation calculations, and a true GMT function tracks a second time zone on an independently adjustable 24-hour hand — the configuration pilots actually use, not a simplified dual-time display.
Inside is Citizen's Calibre 9054 automatic: 24 jewels, 28,800 vibrations per hour, a 50-hour power reserve, and accuracy of -10/+20 seconds per day — considerably tighter than Citizen's entry-level mechanical movements. It also offers hacking for setting to the exact second, manual winding, and magnetic resistance to 16,000 A/m. The 44.5mm stainless steel case carries sapphire crystal with anti-reflective coating, a screw-down crown, and 200 metres of water resistance.

Why You'll Love It
- This is an officially licensed Blue Angels limited edition — the blue and yellow scales are the squadron's own colours, not a styling choice, which is exactly what makes it collectible.
- A true GMT means the 24-hour hand adjusts independently, so you can track a second time zone properly. It's the configuration pilots and frequent travellers actually want, rather than a simplified dual-time readout.
- The slide-rule scale performs flying distance and navigation calculations — a working aviation tool, not decoration.
- Calibre 9054 runs to -10/+20 seconds per day, meaningfully tighter than the -20/+40 typical of entry-level mechanical movements. This is a serious automatic.
- A 50-hour power reserve means it survives a full weekend off the wrist and is still running on Monday morning.
- Hacking lets you stop the seconds hand to set the time precisely, and manual winding means you can top it up without waiting for wrist motion — neither is standard at the entry level.
- Magnetic resistance to 16,000 A/m protects timekeeping around the electronics and magnets of everyday life, which matters more for a mechanical watch than a quartz one.
- Sapphire crystal with anti-reflective coating, a screw-down crown and 200m water resistance make this genuinely durable — a tool watch, not a display piece.

Frequently Asked Questions
Who are the Blue Angels?
The Blue Angels are the U.S. Navy's flight demonstration squadron, known worldwide for precision formation flying. Citizen produces officially licensed Promaster editions in their colours — the blue and yellow scales on this watch are the squadron's own, which is a large part of what makes these editions collectible.
What does the slide rule do?
It's a circular calculator built into the watch, used in aviation for flying distance, speed, fuel and unit-conversion calculations. Line up the scales to read off the result — the same principle as the navigation computers pilots have used for decades.
What is a "true" GMT?
The 24-hour GMT hand can be adjusted independently of the main hands. That means you can set a second time zone without disturbing the time you're keeping — the arrangement travellers and pilots actually need, rather than a fixed dual-time display that moves with the main hands.
Is this a pilot's watch or a dive watch?
It's a pilot's watch — part of Citizen's Promaster Sky line, with a slide rule for navigation calculations and a GMT hand for time zones. The 200-metre water resistance is there for durability and makes it perfectly capable around water, but the watch is designed and equipped for aviation.
What does "automatic" mean?
An automatic watch is powered by the natural movement of your wrist — a rotor inside the case winds the mainspring as you wear it, so no battery is needed. This calibre also supports manual winding via the crown, so you can top up the reserve directly if it's been sitting unworn.
How accurate is it?
Calibre 9054 is rated at -10/+20 seconds per day, which is notably tighter than the -20/+40 typical of entry-level mechanical movements. It won't match a quartz watch — no mechanical movement does — but it's a serious automatic by any measure.
What is magnetic resistance and why does it matter?
Magnetic fields from laptops, speakers, phone cases and bag clasps can disturb the balance spring in a mechanical watch and throw off its timekeeping. This movement is rated to 16,000 A/m, which protects against the fields encountered in everyday life.
How long does the power reserve last?
Approximately 50 hours when fully wound — enough to sit through a full weekend off the wrist and still be running.
Can I swim or dive with this watch?
Yes to swimming — 200 metres (20 BAR) with a screw-down crown handles swimming and water sports comfortably. It isn't built as a dedicated dive instrument, but the water resistance is genuinely substantial.
Will 44.5mm fit my wrist?
44.5mm is a large watch and suits larger wrists best — the size is partly what makes the slide-rule scale legible. At 12.7mm thick it's reasonably proportioned for its diameter. Worth trying on in-store if you're unsure.
Does a mechanical watch need servicing?
Yes. Unlike a quartz watch, an automatic has moving parts and lubricants that wear over time. Citizen recommends periodic servicing to keep timekeeping and water resistance within spec. Any City Chain outlet can arrange this — bring your warranty card.
What warranty does this watch come with?
The NB6044-54L comes with a 3-year warranty when purchased from City Chain Singapore, an authorised Citizen retailer. Keep your warranty card and proof of purchase — both are required when submitting the watch for service at any City Chain outlet.
