Wrist Watch CASIO EF-129D-2AVEF stainless steel case and band, mineral glass, SR626SW battery

The CASIO EF-129D-2AVEF is a men's analog wrist watch featuring a stainless steel case and matching stainless steel band, mineral glass, and a reliable quartz movement powered by an SR626SW battery (approx. 3 years). The dial includes day and date displays and a Neo-display luminous coating for improved legibility in low light. A screw-locked back protects the movement while allowing relatively simple battery replacement, and a safety catch on the clasp helps prevent accidental opening. Water resistance to 10 bar (100 metres) makes the watch suitable for swimming and snorkelling.

Advantages

The mineral glass offers enhanced scratch resistance to keep the dial clear over time, while the stainless steel case and band provide durability and a classic appearance suitable for both everyday and formal wear. Neo-display luminous coating increases readability in the dark after short exposure to light. The screw-locked back and secure clasp contribute to overall robustness, and the quartz movement with SR626SW battery ensures consistent timekeeping with an expected battery life of around three years.

Suitable for

• Daily wear and business attire where a durable analog watch is required
• Outdoor activities such as swimming and snorkelling (water resistance up to 10 bar / 100 m)
• Users who prefer low-maintenance quartz watches with day and date functions
• Situations requiring clear night-time legibility thanks to Neo-display

When it may not be suitable

This model does not offer smartwatch connectivity, advanced timing features like chronograph or GPS, nor is it rated for professional diving. Individuals needing water resistance beyond 10 bar or specialized dive functions should consider a dedicated dive watch. Those preferring automatic or mechanical movements will find this quartz watch does not meet that preference.

Key specifications

• Movement: Quartz (SR626SW battery, approx. 3 years)
• Case material: Stainless steel
• Band material: Stainless steel with safety catch
• Glass: Mineral glass (scratch resistant)
• Functions: Analog time, day display, date display, Neo-display luminous coating
• Back: Screw-locked back
• Water resistance: 10 bar / 100 metres (suitable for swimming and snorkelling)

How to use

Set the time and date using the crown following the manufacturer's instructions: pull the crown to the appropriate position to adjust day, date and hands, then push it back in to resume operation. Wear the watch regularly or store it away from strong magnetic fields to maintain accuracy. Replace the SR626SW battery when the watch stops or shows signs of low power; a qualified watch technician is recommended for battery replacement to preserve the screw-locked back seal and water resistance.

What to consider before purchase

• Desired movement type: this is a quartz watch with an SR626SW replaceable battery (approx. 3 years life)
• Water activities: water resistance is 10 bar (100 m), not suitable for professional diving
• Glare and scratch resistance: mineral glass provides scratch resistance but is not as hard as sapphire
• Style and size: stainless steel case and band provide a classic look—check case dimensions and band fit before purchase

Usage recommendations

To preserve water resistance, have seals inspected after battery changes and avoid operating the crown when the watch is submerged. Clean the stainless steel band regularly with a soft cloth and mild soap solution, rinse and dry thoroughly. For long-term storage, remove the battery if the watch will not be used for extended periods to avoid potential leakage.
