Citizen Promaster Dive E365 Professional Diver 300M Eco-Drive 46 mm Gradient Blue Dial Limited Edition Watch [BN1025-08L]

The Citizen Promaster Dive E365 BN1025-08L represents the next evolution of Citizen's legendary professional dive-watch collection. Combining the groundbreaking Eco-Drive Calibre E365, robust 300-metre dive capability, and a striking ocean-inspired gradient blue dial, this impressive tool watch is engineered for those who demand uncompromising performance both above and below the surface.

Drawing inspiration from the colours of the sea, the dial transitions from vibrant blue tones into deeper shades reminiscent of the ocean's darker depths. This dramatic gradient effect gives the watch a unique visual identity while maintaining the exceptional legibility required of a professional dive instrument. Large luminous hands and oversized markers ensure excellent visibility in all conditions, whether exploring underwater environments or navigating everyday life.

Built for serious adventure yet refined enough for daily wear, the BN1025-08L demonstrates why Citizen remains one of the world's most respected manufacturers of professional dive watches.

The Revolutionary E365 Movement

At the heart of the BN1025-08L is Citizen's remarkable Calibre E365 Eco-Drive movement.

Named after its extraordinary capability, the E365 can operate for approximately 365 days on a full charge, representing one of the most significant advancements in Eco-Drive technology. Powered by any light source, the movement continuously converts light into stored energy, eliminating the need for routine battery replacement while delivering exceptional reliability.

For divers, travellers, and everyday wearers alike, the benefit is simple: unparalleled convenience and long-term dependability.

Professional Diver 300 Metres

The Promaster Dive E365 was designed as a true professional-grade diving instrument.

Its robust stainless steel construction, screw-down crown positioned at 4 o'clock, and 300-metre water resistance provide the confidence required in demanding underwater environments. The aggressive unidirectional bezel offers secure operation while timing dives, and the highly luminous display ensures excellent readability when visibility is limited.

Every component has been engineered with functionality in mind, resulting in a watch that feels purpose-built rather than merely styled to resemble a dive watch.

Inspired by the Ocean

While the technical specifications are impressive, the dial is what immediately captures attention.

The gradient blue finish reflects the changing colours of the ocean as sunlight penetrates deeper beneath the surface. Combined with the bold case architecture and professional dive-watch layout, the watch delivers a powerful visual presence that feels distinctly Promaster.

Unlike many monochromatic dive watches, the BN1025-08L offers personality and character while remaining completely functional as a professional tool watch.

BENEBiOL™ Sustainable Strap

Citizen pairs the watch with a durable blue BENEBiOL™ biomass-based polyurethane strap.

Developed using plant-derived materials, the strap offers outstanding flexibility, durability, and resistance to harsh marine environments while supporting Citizen's commitment to sustainability. Its comfortable fit and rugged construction make it ideally suited to both diving activities and daily wear.
