Genuine Seiko Leather Strap RS07S18BK – 18 mm – Black – Contrast Stitch (JDM)

This original Seiko leather strap with the reference RS07S18BK represents a sporty yet elegant interpretation of classic Seiko strap aesthetics. It is a high-quality calfskin leather strap in deep black, which deliberately sets accents with its contrasting decorative stitching in brown without being intrusive.

The leather has a finely grained, slightly matte surface and provides a robust yet comfortable grip. The medium padding ensures high wearing comfort and gives the strap a valuable presence on the wrist. The clean edge finishing and uniform stitching underline the typical Seiko manufacturing quality.

The strap is equipped with a solid stainless steel pin buckle in silver optics, subtly signed. The strap width is 18 mm, tapering to 16 mm at the buckle. The strap features quick-release spring bars, allowing for tool-free strap changes.

This model is part of the Japanese Seiko accessory program and is not regularly available through Seiko Germany, but primarily intended for the Japanese market.
