Casio has introduced the G-Shock 2500 series, nicknamed the "CasioNaut" by enthusiasts for its case design reminiscent of luxury sports watches. This new analog-only G-Shock features a unique stopwatch complication integrated into the date wheel and a novel Shock Release Hand system for the minute hand.

The "CasioNaut" nickname stems from its case sides, which evoke luxury sports watches.
The watch is fully analog with a two-handed central time display, a small seconds subdial, and a date display, lacking screens or Bluetooth.
The Shock Release Hand system uses magnets to hold the minute hand, allowing it to absorb impacts and reset automatically if misaligned.
The stopwatch function is activated by cycling modes via the 8 o'clock pusher, with the date wheel displaying 'ST' and then counting minutes.
The date wheel also functions for setting the perpetual calendar, using the date number to select year positions before setting month and date.
The bracelet features a full-width link design with a non-articulating endlink, extending the effective lug-to-lug from 46mm to 57.5mm.
The bracelet's links have substantial gaps and are secured with spring bars, leading to a loose fit and a simple pressed-steel clasp with limited micro-adjustment.
