New Modules and Features
The updated Casio DW-5900U watches come with advanced modules. Unlike the earlier models, DW-5900-1 and DW-5900BB-1 which feature the 3465 module, the new versions utilize the 3536 module. Additionally, they boast improved backlights; the latest versions are equipped with LED Super Illuminator instead of the previous Electro-luminescent backlights.
Design and Appearance
The Casio G-Shock DW-5900UBB-1 presents a sleek all-black design, featuring a resin case and strap. The main LCD display showcases a black background with light figures, while the Triple Graph maintains the conventional light background. On the other hand, the DW-5900U-1 also sports a black resin case and strap but includes vibrant red, blue, and white accents. The displays are inverted, with a lighter main display against a darker Triple Graph background.
Functionality and Durability
Features of the DW-5900 include world time support, a stopwatch, and multiple daily alarms. They are advertised as precise within 15 seconds per month, displaying the time, date, and day of the week on the larger display. These shock-resistant watches are also water-resistant up to 200m and are designed to last for 10 years using a CR2025 battery.
At the Casio online shop in the UK, both the DW-5900UBB-1 and DW-5900U-1 watches are listed at £80 RRP. They are expected to launch later in January 2026, though a specific date has not been provided. Interested customers are encouraged to “sign up now” through a button on the product page to get an email alert when they become available. It remains uncertain when the Casio G-Shock DW-5900UBB-1 and DW-5900U-1 watches will be released in other parts of Europe or in the United States.
