Reference / Product Code

Description

Original SEIKO leather strap made of high-quality, smooth calfskin in dark navy blue. The strap has a classic straight cut, is lightly padded, and neatly finished with tonal contrast stitching. The surface is matte-silky, very uniform, and deliberately understated – typical for higher-quality SEIKO standard replacement straps from the Japanese range.

Equipped with a solid stainless steel pin buckle and integrated quick-release spring bars, allowing for tool-free strap changes.

The back is neatly embossed with "SEIKO CALF" and the reference RS07S20NY, unequivocally confirming its originality.

This strap is not part of the regular European SEIKO accessory program, but comes from Japanese domestic distribution (JDM).
