The dual analog-digital display is clean and easy to read, with LED illumination for visibility in low-light conditions.

Built for those who demand both performance and personality from their timepieces, the GM-2100 Oak Green Rainbow Edition is a perfect balance of form and function. It’s ideal for everyday wear, yet bold enough to turn heads wherever you go.
