At the heart of the MTSigma watch beats the Miyota 8215 automatic movement, a Japanese caliber celebrated for its reliability and precision. Operating at a frequency of 21,600 vph (3 Hz), this caliber delivers a generous power reserve of 40 hours, keeping perfect time even after several days off the wrist.

Lightweight yet robust, this material delivers exceptional longevity and a notably comfortable fit on the wrist. The bracelet finish alternates between brushed and polished surfaces, creating an elegant visual contrast that enhances the watch's sophisticated character. The deployant clasp ensures a secure and effortless fit, adding a refined touch of luxury and practicality. With a lug width of 20 mm, this bracelet offers a perfectly balanced and stable wear.
The water resistance of the MTSigma watch is rated at 10 ATM, or 100 meters. This rating means the watch is not only splash-proof for everyday wear but also built for water activities such as swimming and recreational diving. This level of water resistance is reinforced by the screwed caseback, providing optimal protection for the internal mechanical components against moisture.
