Citizen Radio-Controlled AT8304-57A – Atomic precision with white dial
The Citizen AT8304-57A is part of the Radio-Controlled H800 collection, where technological innovation meets elegant and functional design. Equipped with the Eco-Drive Radio-Controlled Caliber H800 movement, it converts any light source into energy and eliminates the need for battery replacement, offering 6 months of power reserve (or up to 2 years in power-saving mode).
Radio-control technology ensures automatic synchronization with atomic signals transmitted from Japan, USA, Germany, and China, guaranteeing absolute precision anywhere. The model also offers a perpetual calendar valid until 02/28/2100, World Time with 26 cities, 1/20-second chronograph up to 60 minutes, automatic daylight saving time, and a charge level indicator.
With a 41 mm stainless steel case and a grey finish, the watch features robust and refined lines. The white dial, protected by a flat sapphire crystal with anti-reflective treatment, stands out for its clarity and legibility, with applied indices and luminous hands. The internal slide rule adds practicality and reinforces the technical inspiration of the piece.
The solid steel bracelet with a double-button clasp ensures security and comfort. With anti-magnetic resistance and water resistance up to 20 bar (200 meters), the AT8304-57A combines cutting-edge technology, atomic precision, and sophistication for daily use and international travel.
