Casio to Release Lightweight Mechanical Watch with Excellent Readability

TOKYO, Oct. 29, 2026 /PRNewswire/ — Casio Computer Co., Ltd. announced the release of the CMK‑100, a lightweight mechanical timepiece with excellent readability. Combining comfort and practicality, the watch is suitable for a variety of occasions, from everyday use to business settings.

The new CMK‑100, powered by an automatic movement, is designed for practicality in day-to-day life, with a lightweight construction and excellent readability. Developed in response to growing demand for mechanical watches, the watch is a handsome accompaniment to daily living.

The case is made with lightweight titanium, providing a comfortable fit even during extended wear. The case and bezel feature a hairline finish that gives the metal a refined appearance.
