Casio Reveals AE-1600HX Series Details
Casio has just made it official by putting the AE-1600HX series on their international website, which confirms all the info from previous retailer listings. The models include AE-1600HX-1BV and AE-1600HX-3AV, both of which are kinda budget-friendly digital watches that pack a punch with their long battery life and larger case sizes, a signature of the AE-1600H series.
Battery Life and Water Resistance
The most attractive thing about these watches would probably be their promise of a 10-year battery life, powered by a CR2032 cell. They’re also water resistant up to 100 meters, which makes them quite decent for sports or everyday use. Moreover, the AE-1600HX-1BV features a negative display—the all-black look seems to be a hit with many buyers out there.
Design and Construction
The case dimensions of this timepiece are listed as 54.1 × 49.7 × 15.9 mm, and it weighs just 55 grams. It uses resin for the case and strap, with a resin glass protecting the display. One interesting thing about these is the “Extra Long Strap” feature, supporting wrist sizes from 145 mm to 235 mm, which makes it suitable for larger wrists or even worn over thicker clothing or jackets.

- 1/100-second stopwatch

Availability and Pricing
These models have been seen on international retailer sites recently which gave us clues about most of their specs early on. The official listing doesn’t really add much new. No official prices are announced yet, but they’re expected to be available for purchase in April 2026. On one website, it’s listed at €39.90 (~$46), so the official price should be similar or maybe a little less.
