Pro Trek PRW-30 Series with STN LCD: Smaller than PRW-3000

Another new Pro Trek series revealed by Casio, the PRW-30 is expected to be launched this summer. This digital model is notable for its smaller size (51.6 x 45.2 x 12.3 millimeters) and light weight (66 grams). (In comparison, the PRW-3000 measure 56 x 47 x 12.3 mm.)

The PRW-30 is equipped with an STN LCD display which provides better contrast and viewing angles compared to a standard LCD display. The display font has also been redesigned with a bold style to improve visibility. Large sensor measurement buttons for compass bearing, barometric pressure, altitude, and temperature are easily accessible on the right side of the watch. Features include 100-meter water resistance, Tough Solar power, Multi-Band 6 auto radio time adjustment, Triple Sensor, sunrise/sunset time, and low temperature operation (-10C/14F).

The PRW-30 comes with a 23-mm-wide Durosoft silicone band with quick-release slide levers. Other bands, including a carabiner attachment, a field loop band for wearing over gloves, and a cloth band, are in the planning stages and may later be available separately. (A carabiner attachment is included with the PRW-30AE-2JF.)

The PRW-30 series is slated for a July 2020 release with three debut models, with two more models planned for August 2020. These dates are subject to change due to the coronovirus.

Thanks for your knowledge, G-Central! I didn’t know that.


I wonder what the retail price will be in the West as that’s around $420. The 3100s retail for around $350, with street price around $230.

BTW, the PRW3100YB-1 is regularly on sale direct from Casio’s eBay page. It’s currently sitting at $150. They must be trying to clear them out.
