This year, Seiko has marked its 145th anniversary, and the Japanese watchmaker celebrates the milestone with a limited-edition series of watches inspired by Edo purple (Edo-murasaki), a traditional Japanese colour symbolising the brand’s deep, generation-spanning ties with Tokyo – the metropolis formerly known as Edo, where founder Kintaro Hattori opened his first timepiece repair and sales shop in 1881 – in its Ginza district. It was during the Edo era (1603–1868) that the ‘Edo purple’ colour emerged as one of the most defining and popular colours.

‍

The six-model anniversary series spans Seiko’s renowned lines – two in Prospex, and one each in the Astron, Presage, Seiko 5 Sports, and Seiko Selection – with all models marked “LIMITED EDITION” on their casebacks. The timepieces will be available for purchase at Seiko Boutiques and selected retailers worldwide from October 2026.

The Prospex Alpinist HBC006 revisits the original 1959 Seiko Laurel Alpinist and includes a modern interpretation of its distinctive “Alpinist” logotype beneath the Seiko name.

Its stainless-steel case measures 39.5 mm, finished with a super-hard coating and topped by an anti-reflective sapphire crystal. Beating inside is the automatic Calibre 6R55 at a frequency of 21,600 vibrations per hour (3 Hz), with a power reserve of 72 hours. The watch is water-resistant up to 200 metres and magnetically resistant up to 4,800 A/m. Limited to 7,000 pieces, it is priced at approx. INR 86,000.
