Seiko Presage “Komorebi” 木漏れ日 HCB002J Automatic – 38.5 mm Made in Japan (JDM)

The Seiko Presage “Komorebi” captures the traditional Japanese aesthetic concept of komorebi (木漏れ日): the effect of sunlight gently filtering through the leaves of trees. Its green dial with a textured finish offers a subtle interplay of light and shadow depending on the angle of view, adding depth and a refined presence on the wrist.

The stainless steel case features a balanced diameter of 38.5 mm and a thickness of 11.8 mm—classic proportions ideal for both formal and everyday wear. Inside, it houses the in-house automatic caliber 4R35, a mechanism of proven technical reliability that incorporates manual winding, a hacking seconds function for precise time setting, and a power reserve of approximately 41 hours.

The watch is completed with a vintage-inspired domed Hardlex crystal, a date window at the 3 o’clock position, magnetic resistance compliant with Japanese standards, and a brown cowhide leather strap that enhances the dial’s natural contrast. This timepiece is entirely manufactured in Japan (Made in Japan) and is intended for the Japanese domestic market (JDM).
