Original SEIKO Leather Strap RS01C18NY (18–16 mm) - Blue with Stainless Steel Pin Buckle (JDM)

This original Seiko leather strap with reference RS01C18NY is a high-quality OEM replacement strap offered in Japan that is not regularly sold through Seiko Europe. Accordingly, it is a model that is only available in Germany through direct import.

The strap is made of high-quality cowhide leather (calfskin) with a subtle, even grain in a crocodile-embossed pattern. The surface is understated and clearly oriented towards classic dress and business watches. The craftsmanship is precise, with cleanly set seams and even edge finishing.

Characteristic is the taper from an 18 mm lug width to a 16 mm buckle width, which makes the strap appear particularly well-balanced on classic Seiko cases. The mounted original Seiko stainless steel pin buckle is signed and corresponds to the factory version.

The strap features an integrated quick-change system for the spring bars, which allows for tool-free strap changes without compromising originality or stability.

The back is cleanly finished, with Seiko embossing and model and size markings. The strap comes in its original Seiko packaging from Japan.
