Seiko has expanded its Lukia Essential Collection in Japan with two limited-edition radio-controlled watches designed as a matched pair. The release centers on the Evergreen concept, a theme Seiko uses to reflect a bond meant to last, while keeping the overall design practical for everyday wear.
The pair consists of HEC001 and HEE001, two models that share the same design language but come in different sizes. Each model is limited to 600 units, which places the release firmly in exclusive territory for collectors who want a classic look supported by modern functionality.
A restrained design built around a soft green dial
The most immediate visual cue is the pale green dial, which gives the watches a distinct identity without making the design feel busy. Seiko pairs that dial with silver-tone indices and Roman numerals at 12 and 6 o’clock, creating a layout that stays formal and easy to read.
Both watches use three-hand analog displays and a simple date window. The case and bracelet are made of stainless steel in a silver tone, which keeps the appearance cohesive and understated.
That approach gives the series a clean, balanced character. The green accent stands out enough to define the collection, but the watches still retain the classic Lukia Essential Collection style that supports a wide range of settings.
Two sizes, one matched concept
HEC001 is the larger model in the duo and uses the 7B62 caliber. It is a quartz movement with radio-controlled timekeeping and solar power support, combining accuracy with reduced dependence on conventional battery changes.
HEE001 takes the same concept and scales it down into a smaller case size. Seiko equips it with the 1B32 caliber, and it also features radio-controlled functionality and solar charging, so the core experience remains aligned with the larger version.
The size difference gives the collection a practical advantage. The pair can be worn together as a coordinated set, but each model also works on its own for buyers who prefer a specific fit for the wrist.
Focus on accuracy and ease of use
The main technical appeal of the Evergreen release lies in its radio-controlled and solar-powered setup. Those features are aimed at keeping time precise while also reducing routine maintenance tied to battery replacement.
Seiko also includes a full automatic calendar and a power-saving mode. The calendar adds convenience in daily use, while the low-power function helps manage energy more efficiently when the watch is not actively worn.
Rather than adding complex complications, Seiko keeps the emphasis on clarity and reliability. The result is a watch pair that targets buyers who want an elegant design without unnecessary visual or mechanical clutter.
Limited production strengthens the collector appeal
The limited run is an important part of the story. Seiko has set the production cap at 600 units for each model, giving both HEC001 and HEE001 a clear collector appeal from the outset.
The matched sizing, coordinated color palette, and shared Evergreen theme reinforce the idea that these watches were designed to be viewed as a pair. That identity is not only part of the branding, but also visible in the way the two models were developed with matching aesthetics.
For Seiko followers who appreciate classical styling with modern utility, the combination of solar power, radio-controlled precision, and a limited-edition format makes this release stand out within the Lukia Essential Collection.
Price and availability in Japan
Seiko says the Lukia Essential Collection Limited Edition Evergreen will launch in Japan in May 2026. The official price is set at ¥80,300 for each model, so the choice between the larger and smaller watch does not affect the final price.
At this stage, the available information focuses on the Japanese market. With its pale green dial, limited production run, and coordinated pair concept, the Evergreen release gives Seiko a restrained but distinctive limited edition within the Lukia Essential Collection.
