Seiko Prospex Alpinist SPB505J1
Technically advanced, stylistically close to the 1959 original, the Laurel Alpinist. The new calibre 6R55 provides an impressive 72-hour power reserve, meaning three full days of mechanical precision. Reliable, robust and ready to master any adventure. Ideal for anyone who wants to rethink time and wear history on their wrist. The rich green colour is reminiscent of dense coniferous forests and vast mountain slopes. This colour radiates calm and emphasises the original outdoor character of the Alpinist. The SPB507J1 also sets a sustainable example with its responsibly produced leather strap, combining aesthetic appeal with a conscious use of resources.
