Citizen Promaster Mechanical Diver 200M Fujitsubo 35th Anniversary Limited Edition Automatic Blue Dial Super Titanium™ 41 mm Bracelet Watch [NB6026-56L]

The Citizen Promaster Mechanical Diver 200M Fujitsubo 35th Anniversary Limited Edition NB6026-56Lcelebrates one of the most remarkable stories in modern watchmaking. Inspired by the legendary Citizen Challenge Diver that was discovered years after being lost at sea—still functioning despite being covered in barnacles—this commemorative edition honours both that incredible story and the 35th anniversary of the Promaster collection. 

Limited to only 4,500 pieces worldwide, the NB6026-56L is among the most collectible Fujitsubo models ever produced. The vivid blue dial draws inspiration from the crystal-clear waters surrounding Long Reef Beach in Australia, where the famous Challenge Diver was found. Complementing the dial is a bold black aluminium bezel and a Super Titanium™ case and bracelet finished with Citizen's premium Duratect Platinum surface treatment, creating a watch that feels both luxurious and purpose-built. 

For collectors, dive-watch enthusiasts, and fans of Japanese horology, this reference represents one of the most compelling modern releases in the entire Citizen catalogue.

Collector Appeal

Unlike the standard Fujitsubo models, the NB6026-56L was created specifically as a commemorative anniversary edition.

With worldwide production limited to 4,500 pieces, availability is naturally restricted. Once retailer allocations are exhausted, no additional production will occur. The special Promaster 35th Anniversary caseback engraving and exclusive collector presentation elevate the ownership experience even further. 

This is precisely the type of watch collectors look back on years later as one of the defining special editions of its era.

The Legend of the Fujitsubo

The story behind the Fujitsubo is one of the most fascinating in dive-watch history.

Several years after a Citizen Challenge Diver was lost at sea, it was reportedly discovered attached to a mangrove root on Long Reef Beach, Australia. Despite prolonged exposure to harsh marine conditions, the watch was still functioning. This remarkable discovery became part of Citizen folklore and ultimately inspired the modern Fujitsubo collection. 

The nickname "Fujitsubo," which translates to "barnacle" in Japanese, pays tribute to that extraordinary event.

In-House Calibre 9051

Powering the NB6026-56L is Citizen's highly regarded Calibre 9051 automatic movement.

The movement operates at 28,800 vibrations per hour and delivers approximately 42 hours of power reserve. Designed for modern life, it features enhanced anti-magnetic protection rated to 16,000 A/m, helping shield the watch from the magnetic fields generated by smartphones, tablets, laptops, and other electronic devices. 

Performance specifications include:

• 42-Hour Power Reserve
• 24 Jewels
• 28,800 Vibrations Per Hour
• Anti-Magnetic Resistance of 16,000 A/m
• Accuracy of -10/+20 Seconds Per Day

Super Titanium™ with Duratect Platinum

Citizen's expertise with titanium is unmatched within the industry.

The NB6026-56L utilizes Super Titanium™ treated with Duratect Platinum, producing an exceptionally bright finish while maintaining outstanding scratch resistance and lightweight comfort. The result is a watch that weighs significantly less than comparable stainless-steel divers while offering superior everyday wearability. 

For enthusiasts who appreciate titanium dive watches, this is one of the finest executions currently available.

Professional Dive-Watch Credentials

The NB6026-56L is built as a true professional dive watch and complies with ISO Diver 200M standards.

• ISO-Certified Diver's Watch
• 200 Metres Water Resistance
• Screw-Down Crown
