Description
The Seiko Prospex HBC010 is a 1965 Limited Edition European Exclusive diver’s watch in Calmwater Green. Exclusively available in Europe, with only a small number available in the UK, this special edition Prospex model celebrates Seiko’s long-standing heritage in professional dive watches.
In 1965, Seiko created Japan’s first ever diver’s watch, marking the beginning of the brand’s reputation for innovative, reliable and robust diving timepieces. This HBC010 model takes inspiration from that important moment in Seiko history, combining classic dive watch styling with modern specification and a distinctive green dial design.
The deep green dial is inspired by calm waters and is finished with a sunray texture designed to catch the light like ripples across the surface. Gold-coloured accents add warmth and contrast, while LumiBrite on the hands and indices improves visibility in low light and underwater conditions.
Built as a 300m Air Diver, this Seiko Prospex watch features a 40mm case with super-hard coating for added durability. The aluminium insert unidirectional rotating bezel is designed for safe diving use, while the 300m water resistance makes this model suitable for professional diving environments.
The watch is powered by Seiko’s in-house 6R55 automatic calibre, offering a 72-hour power reserve and an accuracy of -15/+25 seconds per day. This movement provides reliable automatic performance, making the watch practical for regular wear as well as adventure use.
This model is supplied on a stainless steel bracelet and also comes with an additional black silicone strap, allowing the look and feel of the watch to be changed to suit different occasions. The silicone strap gives the watch a more practical sports finish, while the bracelet keeps the design classic and versatile.
Prospex stands for “Professional” and “Specifications,” reflecting Seiko’s focus on practical, durable and reliable watches designed for sports lovers, divers and adventure seekers. With its limited European availability, Calmwater Green dial and strong dive watch credentials, the Seiko Prospex HBC010 is a standout choice for collectors and Seiko enthusiasts.
As a Limited Edition European Exclusive, the Seiko Prospex HBC010 is already a highly restricted release. With only a small number available in the UK, this Calmwater Green model offers an even more exclusive opportunity for Seiko collectors and Prospex enthusiasts looking for something distinctive, limited and closely tied to Seiko’s dive watch heritage.
