Wrist Watch EDIFICE / G-SHOCK Casio GA-2100K-1AER — Analog-digital quartz, shock-resistant, 200M water resistance

Casio GA-2100K-1AER is an analog-digital quartz wrist watch from the EDIFICE / G-SHOCK family designed for reliable everyday timekeeping. The watch pairs traditional hour and minute hands with a small digital display that shows time, date and basic chronograph/timer information. Built to withstand shocks and offering 200M water resistance, this model is suited for active users who need a robust, low-maintenance timepiece.

Advantages

The combination of analog hands and a digital display gives clear, at-a-glance time reading while retaining useful digital functions such as stopwatch and date. Quartz movement ensures accurate timekeeping with minimal maintenance. Shock-resistant construction protects the movement and case from impacts, and the 200M water resistance allows use in swimming and surface water activities. The compact profile and durable materials make the watch resistant to daily wear.

Suitable for

• Everyday wear where a reliable, low-maintenance watch is required
• Outdoor activities and sports that involve impacts or rough handling
• Water-related use such as swimming and snorkeling (no deep diving)
• Users who prefer a mix of analog readability and digital functions

When it may not be suitable

This model is not intended for professional deep-sea diving despite its 200M water resistance rating; professional diving equipment with specific dive features would be more suitable. The watch does not offer advanced smart features (such as Bluetooth connectivity or GPS), so it may not meet needs for smartphone integration or fitness tracking.

Key specifications

• Movement type: Quartz analog-digital
• Shock resistance: Yes, protective shock-resistant construction
• Water resistance: 200 meters (suitable for swimming and snorkeling)
• Display: Analog hands plus digital sub-display for time, date and stopwatch/timer
• Functions: Time, date, basic stopwatch/timer
• Case and strap: Durable materials designed for everyday and active use

How to use

Set the analog time using the crown and adjust the digital display following the manufacturer’s mode button sequence to set time, date and use the stopwatch or timer functions. Use the watch’s buttons to switch modes on the digital display and to start/stop/reset the chronograph features. Regularly check the crown and button seals after exposure to water and rinse the watch with fresh water after swimming in chlorinated or salt water to maintain seals and finishes.

What to consider before purchase

• Confirm that quartz analog-digital functionality meets your needs versus full analog or smartwatch options
• Consider whether 200M water resistance is sufficient for your intended water activities (not a substitute for professional dive equipment)
• Check strap material and sizing to ensure comfort and fit for daily wear
• Decide if absence of smartphone connectivity and advanced sensors is acceptable

Usage recommendations

For longest service life, avoid exposing the watch to strong chemical solvents, excessive heat, or prolonged direct sunlight. After swimming in salt or chlorinated water, rinse the watch in fresh water and dry thoroughly. Have periodic battery and seal checks performed by an authorized service provider to maintain water resistance and reliable operation.
