The Citizen High Precision Eco-Drive AQ4100-57B from Japan!!

As something that accompanies the future.

Everything is designed to be a long-lasting partner in life. The culmination of technology and passion that continues to mark time with a precision of less than 5 seconds over the course of a year—365 days—now resides on your wrist.
The brand's symbol, the "Eagle," gracefully spreads its wings on the dial, with a dynamic pattern created through molding technology and coated with metallic paint.

No need for regular battery replacements
Eco-Drive, Citizen’s unique light-powered technology, converts sunlight and even the smallest indoor light into energy to keep the watch running. Once fully charged, it will continue to operate even in the absence of light for long periods, eliminating the need for regular battery changes.

Strong against scratches, lightweight, and resistant to rust
Super Titanium, a material treated with Citizen's proprietary titanium processing and surface hardening technology (Duratect), is 40% lighter than stainless steel and boasts more than five times the surface hardness.

Reduces reflections and makes the dial easier to read
Citizen's "Clarity Coating" glass coating technology minimizes reflections by allowing approximately 99% of light to pass through, making the dial easy to read. Even in sunny places like parks or beaches, you can read the time clearly as if the glass were invisible.

Shock- and magnet-resistant, a watch that won’t lose time
The unique "Perfects" technology integrates three features—"JIS Class 1 Magnetic Resistance," "Shock Detection Function," and "Automatic Hand Correction Function"—to prevent the hands from misaligning due to magnetism or shock.
