The Citizen Caliber H570 is a robust analog-digital Eco-Drive movement designed for users who demand digital precision, solar-powered autonomy, and modern styling in one smart package. This caliber powers a variety of watches from Citizen’s Tech, Chronograph, and Performance collections, combining intuitive functionality with a clean analog interface.

With world time support, stopwatch, alarm, and perpetual calendar, the H570 stands out as a reliable everyday tool—especially useful for travelers and multitaskers.

Core Features

The H570 is an advanced hybrid movement that integrates analog and digital functionality into a single, light-powered watch:

• Eco-Drive technology: Solar-powered, no battery replacement needed

• Analog display: Hour, minute, and central seconds

• Digital LCD display: For time, calendar, stopwatch, and more

• World time: 30 cities across multiple time zones

• Perpetual calendar: Auto-adjusts for leap years and varying month lengths

• Chronograph: Measures up to 24 hours in 1/100-second increments

• Alarm: Daily alarm with digital configuration

• Dual time display: Analog and digital time can be set independently

• Backlight/illumination: For digital screen in low-light settings

• Low charge warning: Second hand moves in 2-second intervals

• Power reserve: ~6 months on full charge

• Accuracy: ±15 seconds per month (without radio sync)

• No radio-controlled function in this caliber

This combination makes the H570 a powerful movement for both formal and active lifestyles.

Eco-Drive Solar Technology

As part of the Eco-Drive family, the H570 uses a solar panel beneath the dial to convert light into energy:

• Light sources: Natural sunlight and artificial light

• Charging time:

  • Sunlight: ~3–5 hours for one day of use

  • Full charge (from depleted): ~10–20 hours of direct light

• Power reserve: Approx. 6 months

• Power save mode: Activates in darkness to conserve energy

• Battery: Rechargeable lithium-ion cell (permanent, no routine replacement)

Eco-Drive ensures maintenance-free operation for years, offering both sustainability and reliability.

Operating Modes and Controls

The H570 uses a combination of pushers and crown to control its various modes:

Primary Modes:

• Time Mode: Analog hands show current time; digital display can match or differ

• Calendar Mode: Digital display shows date, day, month, and year

• Chronograph Mode: Stopwatch with split-time and reset functions

• Alarm Mode: One programmable daily alarm

• World Time Mode: Switch digital display to any of 30 time zones; analog hands remain on home time

• Light Mode: Illuminates LCD for nighttime visibility

The analog and digital times can be set independently, which is especially useful for keeping home and travel times visible at once.

Setting and Adjustments

The H570 offers intuitive user control:

• Crown: Used to set analog time and calendar (pull out and rotate)

• Upper and lower pushers: Used to cycle through modes and adjust digital settings

• Mode button: Switches between digital displays (Time, Alarm, Chronograph, Calendar, World Time)

• Backlight: Press and hold a pusher for night viewing

Quick adjustments for DST (Daylight Saving Time) and leap years are automatic via the perpetual calendar function.

Watch Design Integration

Watches housing the H570 movement typically feature:

• 42–45 mm case sizes

• Stainless steel or titanium cases

• Multi-function pushers and a digital window at 3, 6, or 9 o’clock

• Mineral or sapphire crystal

• Water resistance: Usually 100M

• Sporty, aviation, or tech-inspired aesthetics

• Bracelets: Stainless steel, polyurethane rubber, or resin bands

These watches are designed to provide visual balance between analog elegance and digital information.

Maintenance & Durability

With minimal moving parts and Eco-Drive technology, the H570 is very low-maintenance:

• No battery changes

• Regular light exposure keeps it running

• Clean exterior and buttons occasionally

• Water-resistance checks every 2–3 years (if applicable)

This makes it a perfect choice for daily wearers who don’t want to worry about battery replacements or regular servicing.
