Seiko Prospex Alpinist in ‘Classic Pine’ Green Green Dial Men 39.5mm SPB507J1

Seiko Prospex SPB507J1 — Alpinist in 'Classic Pine' Green

The Seiko Prospex SPB507J1 continues a lineage that dates back to 1959, when Seiko's Alpinist collection was first designed for Japanese 'Yama-otoko' — mountain men — who needed a watch reliable enough for treacherous terrain. This reference reworks that archive design in 'Classic Pine' green, a colour drawn directly from Seiko's vintage Alpinist heritage.

Under sapphire crystal, distinctive 'cathedral style' hour and minute hands pair with classic Arabic numerals and wedge-shaped indices — a design language unique to the Alpinist line among Seiko's Prospex collection. The dial carries the traditional Alpinist compass logo beneath the Seiko name, a detail that first appeared on the original 1950s Laurel Alpinist, while the caseback features the 'Mountain Device' emblem, a callback to the field-watch character of the vintage original. The case itself has a super-hard coating applied for added scratch resistance and shine.

Through the exhibition caseback, you can view Seiko's in-house Calibre 6R55 automatic movement — accurate to -15/+25 seconds per day with a 72-hour power reserve. At 39.5mm, the Alpinist sits smaller and more versatile than most modern field or dive watches, while still carrying a genuine 200m water resistance rating, well beyond what its compact size and leather strap might suggest at a glance.

As part of Seiko's Prospex line — short for "Professional Specifications" — the SPB507J1 is built for durability in demanding environments while remaining wearable enough for daily use.

At Zimson, the SPB507J1 comes with full Seiko manufacturer warranty, authentic packaging, and an invoice — as an authorized Seiko retailer in India since 1948.
