Wrist watch CASIO MDV-107-1A2VEF Quartz Stainless steel case 49.5×44.2×12.1 mm Black/Blue

The CASIO MDV-107-1A2VEF is a quartz wrist watch with a solid stainless steel case and contrasting black and blue accents. The watch measures 49.5 × 44.2 × 12.1 mm and is powered by a battery with an estimated three‑year life. Key built features include a uni‑directional (anti‑reverse) bezel for approximate dive timing, mineral glass for scratch resistance, Neo-display luminous coating for long‑lasting visibility after light exposure, and a resin strap with a buckle for secure daily wear. The screw‑locked back protects the movement and allows straightforward battery replacement. This model offers 20 bar water resistance, suitable for water activities and free diving without scuba gear.

Advantages

The solid stainless steel case delivers durable protection and a robust feel while the mineral glass reduces the risk of scratches during everyday use. Neo‑display luminous coating ensures readability in low light after brief exposure to light. A resin band provides flexibility and long‑term wear comfort, and the screw‑locked back improves water resistance and serviceability. The anti‑reverse bezel allows simple tracking of elapsed time for diving or other timing needs.

Suitable for

• Everyday wear and commuting
• Outdoor activities and water sports without scuba gear
• Casual and utilitarian dress where a robust stainless steel case is preferred
• Users who need a readable dial in low light conditions

How to use

Set the time and date using the crown according to the manufacturer's instructions. Turn the bezel to align the marker with the minute hand to measure elapsed time; the anti‑reverse design prevents backward movement. The Neo‑display requires short exposure to light to charge the luminous coating for improved night readability. Replace the battery when the watch stops or shows irregular timekeeping; the screw‑locked back provides protected access for battery replacement by a qualified technician.

Usage recommendations

To maintain optimal performance, avoid exposing the watch to strong chemicals, extreme temperatures, or prolonged sunlight. Rinse with fresh water after use in salt water and ensure the screw‑locked back and crown are properly secured before immersion. For pressure‑related activities beyond recreational free diving, consult a specialist to confirm suitability.
