Long Description

The Seiko SPM400B is a mechanical pendulum metronome specifically designed to deliver impeccable rhythmic precision and a clear sound in educational, studio, and intensive music practice environments. As a 100% analog device, it requires no cables or batteries: simply wind the mechanism to obtain a constant and reliable beat.

This model stands out for its versatility and functionality. Its time signature selector (0, 2, 3, 4, and 6 beats) adds a distinct audible signal on the first beat, helping musicians maintain structural orientation during performance. Additionally, the pendulum’s free-swinging motion provides a key visual cue, highly valued by teachers in group classes, bands, and orchestras.

With durability in mind, Seiko has reinforced the SPM400B’s structure with materials highly resistant to mechanical impact, making it ideal for daily use in music schools. Its front cover is fully removable and can be attached to the back during use to prevent loss. Its innovative carrying handle drastically reduces the risk of drops, making it the go-to choice for musicians on the go who seek the reliability of a leading brand.
