Citizen revolutionizes modern horology with its sophisticated Eco-Drive moon phase lineup. The series includes four striking references: BY1033-01H, BY1034-59A, BY1035-56E, and BY1036-53L.
Specifications
Citizen built these timepieces around a celestial concept centered on lunar cycles and atomic precision. Designers drew inspiration from the night sky, weaving astronomical elements into contemporary dress-watch aesthetics.
Every model in this line shares identical core dimensions and physical architecture. The stainless steel case measures 42mm in diameter across the wrist.
The profile maintains a sleek thickness of 10.72mm. Citizen protects the front with a scratch-resistant flat sapphire glass crystal.
Each watch offers water resistance up to 50 meters, protecting against splashes and brief immersion.
Movement
At the heart of every model sits the advanced Caliber H874 Eco-Drive movement. This solar-powered movement charges from any light source, eliminating regular battery changes completely.
Under normal use, a full charge powers the watch for approximately 6 months. The caliber H874 integrates global radio-controlled atomic timekeeping for superior accuracy.
The movement automatically calculates and displays lunar phases based on received radio signals.
You also receive a perpetual calendar, 24 world city times, dynamic daylight saving control, and a 24-hour subdial.
Citizen equips the hands and main indices with luminous material for low-light visibility.
