Seiko Prospex HBC010 Men's Watch Green • Automatic Calibre 6R55 • Limited Edition Save the Ocean

The Seiko Prospex HBC010 is a diver's watch limited to 1,400 pieces, released exclusively for the European market. Its deep, sun-brushed green dial was inspired by Lake Hallstatt in Austria, giving the watch a truly distinctive character. The case in brushed and polished stainless steel with ultra-hard coating features a unidirectional rotating bezel insert in green aluminium with a 60-minute dive scale — a proven safety feature for every underwater dive.

At its heart beats the in-house automatic movement Calibre 6R55 with manual winding capability, hacking seconds, and a power reserve of 72 hours. The case, tested to ISO 6425, is water-resistant to 300 m and features both a screw-down crown at 3 o'clock and a screw-down case back. The domed sapphire crystal with double-sided anti-reflective coating ensures optimal legibility. With a case diameter of 40 mm and a lug-to-lug length of 46.4 mm, the watch offers excellent wearing comfort. Included are a three-link steel bracelet with folding clasp and diver extension, as well as an additional black silicone strap.
