Original Seiko Diver's Strap DB73BP (20–18mm) – Black (JDM)

Original Seiko Diver strap, model DB73BP, made from high-quality black urethane. This strap belongs to the classic Seiko diver strap family with the distinctive, wave-shaped flex segments in the upper strap area, which ensure increased wearing comfort and better flexibility on the wrist.

The material is specially designed for use with sports and dive watches: saltwater resistant, UV-resistant, and dimensionally stable even with temperature fluctuations. The generous perforation allows for precise adjustment, even over a wetsuit.

Equipped with a solid stainless steel pin buckle with Seiko signature. The strap geometry tapers from 20 mm at the lug to 18 mm at the buckle, making it an excellent match for classic Seiko Diver cases.

This model is not regularly listed in the European Seiko spare parts program and is usually only offered through the Japanese market.
