SEIKO SELECTION SBTM323 Watch

The SEIKO SELECTION SBTM323 introduces the S Series, a lineup dedicated to timeless, standard design that is not influenced by trends.

This solar-powered radio-controlled model features a large, highly legible dial with LumiBrite on the hands and indexes, ensuring excellent visibility even at night. Subtle steps and facets along the case sides and lugs catch the light when viewed from different angles, creating a refined, high-quality appearance.

The three-dimensional indexes not only enhance readability but also give the dial a sharp, confident look. The watch is fitted with a sapphire crystal with Super Clear Coating, offering outstanding clarity and scratch resistance.

In addition to its refined design, the watch is equipped with JIS Class 1 magnetic resistance, delivering a well-balanced combination of practicality, durability, and sophisticated styling.
