Digital Quartz Watch with 100m Water Resistance

The Casio AE-1600H-1AV is a digital wristwatch built with a resin case, resin strap and quartz movement. A black digital display shows the time, month, day and date alongside a dual-time function. The watch is water-resistant to 100m and fastens with a buckle clasp.

Suits daily wear, sport and travel timing

Buyers who want a simple, tough watch for swimming, work or multiple time zones will find the 100m rating, dual-time display and resin construction practical. Anyone who prefers an analogue dial, metal bracelet, solar charging or smartwatch connectivity should consider a different style.

100m water resistance decides the use case

The 100m rating means the watch is suitable for swimming and surface water sports, but not for scuba diving. If your activities need ISO-certified dive depth or a screw-down crown, this model does not meet that requirement.

Questions about this item

What does the 100 m water-resistance rating mean for daily use?

It withstands swimming and snorkelling at surface level; it is not rated for scuba diving or high-pressure water jets.

How does the quartz movement affect timekeeping?

The battery-powered quartz calibre keeps time to within a few seconds per month without manual winding.

Will the 49.70 mm case thickness fit under a shirt cuff?

The resin case measures 49.70 mm thick, so it sits higher on the wrist and may catch on tight cuffs.
