Seiko Prospex HBC010J1 – 1965 Heritage "Lake Hallstatt" Limited Edition 2026

A professional diver's watch with regional character – inspired by Lake Hallstatt.

The Prospex HBC010J1 is a European Limited Edition, combining Seiko's diver's watch tradition since 1965 with an elegant design inspired by the deep green waters of Lake Hallstatt. The green sunray dial reflects light like waves on the surface and is stylishly complemented by gold accents. The green bezel insert rounds off the distinctive look. Limited to 1,400 pieces worldwide – each watch features its individual serial number on the case back.

Design & Character

The 40 mm stainless steel case offers a balanced presence on the wrist. The green sunray dial creates an impressive sense of depth and remains perfectly legible at all times thanks to LumiBrite on the hands, indices, and bezel – even underwater. The sapphire crystal with anti-reflective coating ensures a clear view, while the unidirectional rotating bezel, screw-down crown, and 300-meter water resistance make the watch a fully-fledged diver. The stainless steel bracelet with a folding clasp, diver's extension, and tool-free sliding adjustment offers high wearing comfort. An additional green silicone strap is included; thanks to the drilled lugs, changing straps is quick and easy.
