1959 Sport Watch Re-interpretation. Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and style. This extraordinary timepiece re-interprets the watch that launched a rich legacy of over 60 years of sports watch excellence. Styled to fit contemporary tastes while evoking a vintage feel, this exceptional watch is as smooth and refined as the prized 1959 version, but far more powerful. The blue dial includes the original’s mountain-shaped markers at 12, 6 and 9, ensuring legibility while referring to its mountaineering inspiration, as well as LumiBrite hands and markers, a date calendar and a curved sapphire crystal with anti-reflective coating on the inner surface. The screwdown see-through caseback provides a view of the 24-jewel automatic movement, which beats at a frequency of 21,600 vibrations per hour, with a power reserve of approximately 70 hours, and offers manual winding capability. In stainless steel, with tri-fold push button release clasp. 20 bar, 200M Water Resistant

Specifications

A refreshing combination of blue and white

Inspired by a lifestyle steeped in marine sports, the watch has a blue ceramic bezel and silvery white dial to create a fresh and clean appearance.

Endowed with updated functionality

The 1968 Heritage Diver’s GMT Watch is powered by the Caliber 6R54, which features a GMT function that allows it to display the time in two different time zones. The watch’s specifications have been enhanced to offer 300-meter water resistance.

A new clasp designed for comfort and operability

The new clasp can be adjusted in six steps, each measuring about 2.5mm, for a total range of approximately 15mm. This marks the first time that this clasp has been adopted in a non-limited-edition model. It allows for a comfortable fit at all times, accommodating changes in wrist size during diving and daily life.

This model has a grey sunburst dial and green tinted lume on the hour markers. Surprisingly in the catalog shot and the website image differ in the color of the lume and dial. This color mismatch is a rendering issue and I would expect the lume color to match that used previously on the SLA017.

Movement

From the Alpinist collection, first launched in 1959, these watches were designed for Japanese ‘Yama-otoko’ mountain men to be reliably rugged in treacherous terrain.

Under the sapphire crystal glass, the archive-inspired black dial is complemented by ‘cathedral style’ hour and minute hands, accompanied by classic Arabic numerals and wedge-shaped indices. It features the traditional Alpinist logo under the Seiko logo, which featured on the very first 1950s Laurel Alpinist. The ‘Mountain Device’ logo features on the caseback of these watches, an aspect of the vintage original indicating the field nature of the watch. The case has an applied super-hard coating for increased scratch resistance and shine.

Through the exhibition case back, the in-house automatic 6R55 calibre can be viewed, accurate to -15/+25 seconds per day, with a power reserve of 72 hours.

Prospex is a combination of the words ‘Professional’ and ‘Specifications.’ Seiko Prospex timepieces are engineered to be practical, reliably rugged and durable; built for the high standards required in extreme environments for sports lovers and adventure seekers alike.
