When Watchmaking Meets Modern Space Missions

Japan's connection to space exploration runs deep. From JAXA's lunar missions to traditional astronomical observations, the nation has always looked skyward. This heritage finds its most personal expression in Citizen's Attesa collection, where Japanese precision meets genuine space-age innovation.

The Luna Program: Automated Lunar Tracking

The Luna Program represents a horological breakthrough. Select Attesa models powered by Calibre H874 automatically calculate and display the moon's age based on the current date with no manual adjustment required.

How It Works:

• Radio-controlled time signals determine precise lunar age

• Dedicated moon age sub-dial tracks the complete 29.5-day cycle

• Visual moon phase indicator updates continuously

• Eco-Drive™ solar power eliminates battery changes

Practical Applications: Perfect for photographers planning golden hour shoots, fishermen timing optimal conditions, or gardeners following lunar planting schedules.

Key Models:

• BY1001-66E: 42mm Super Titanium™ case with black dial, perpetual calendar, and world time

• BY1006-62E: Premium DLC coating with radio-controlled timekeeping and enhanced durability

This marks the first analogue light-powered wristwatch capable of automated lunar tracking.

HAKUTO-R Partnership: Real Space Technology

Citizen's space credentials extend beyond inspiration. In 2022, the company partnered with ispace inc. for the HAKUTO-R lunar lander mission, supplying Super Titanium™ for the spacecraft's landing legs.

Super Titanium™ Advantages:

• 40% lighter than stainless steel

• 5x harder surface

• Corrosion resistant

• Hypoallergenic

Commemorative Timepieces:

• AT8285-68Z: Radio-controlled with cosmos-inspired blue dial, chronograph, and world time
  

• CC4067-66E: GPS Satellite Wave with 3-second signal reception, dual time zones, and 39-city world time

• BY1009-64Y: Sakura pink accents with DLC coating, perpetual calendar, and world time functionality

Crafted from the same Super Titanium™ used in Japan's HAKUTO-R lunar lander, these timepieces bring authentic aerospace engineering to the wrist.

Design Innovation: YOZORA

The YOZORA 30th Anniversary model demonstrates space-age aesthetics through Japanese design sensibilities.

Visual Features:

• Moon phase window with pearl ink-printed lunar representations

• Star field-inspired dial

• FujiFilm Structural Colour Ink (eco-friendly, pigment-free)

• Depth-rich surface that shifts with lighting

Featured Model:

• BY1007-60L YOZORA: 42mm Super Titanium™ case with moon phase, radio-controlled timekeeping, and world time

This timepiece combines celestial beauty with practical complications, including world time and perpetual calendars.

Space-Grade Materials for Earth

All Attesa models incorporate Super Titanium™ in cases and bracelets, bringing aerospace performance to daily wear.

Real-World Benefits:

• Lightweight comfort during extended wear

• Scratch resistance for active lifestyles

• Temperature stability for travel
