Highlights:
  • This limited edition Prospex watch is exclusively available in Europe. Limited to 3000 pieces.
  • Taking its name from the original and much-loved Seiko ‘Alpinist’ – launched in 1959 for Japanese ‘Yama-otoko’ mountain men, reliable in treacherous terrain – this watch further evolves the Alpinist specifications and overall design – with a legibility focus.
  • The popular SPB121 Alpinist model is the basis for the design of this European Exclusive – its colourways inspired by the night sky over the mountains.
  • The deep blue dial features a subtle gentle vertical striped pattern and is complemented by ‘cathedral style’ gold-coloured hour and minute hands.
  • Paired with a deep blue calf leather strap, this timepiece is accompanied by an additional navy nylon strap in a special edition box.
  • Through the exhibition case back the in-house 6R35 calibre can be viewed, accurate to -15/+25 seconds per day, with a power reserve of 70 hours; the limited-edition number is engraved on the case back.
  • Ever practical, the watch features a compass functionality, whilst its super-hard coating gives it shine and strong scratch resistance.
  • Prospex is a combination of the words ‘Professional’ and ‘Specifications.’ Seiko Prospex timepieces are designed to be practical, reliable and durable; to meet the high standards required in extreme environments for sports lovers and adventure seekers alike.
  • Stop seconds hand function.
  • Magnetic resistance: 4,800 A/m
  • See-through case back.
  • 200 metres water resistant.
