SEIKO Prospex Alpinist Mechanical GMT Automatic Core Shop Exclusive Limited Edition Watch HBC008J [SEIKO] Men's

3 Days GMT x Simple Compass: A fusion of field watch functionality and worldview. Equipped with the highly reliable and practical Cal.6R54, featuring a long power reserve of 3 days (approximately 72 hours) and GMT function. By using the 24-hour hand (when the GMT hand is as the 24-hour hand) in combination with the simple compass, direction can be easily determined. A new Alpinist design with reliable readability and visibility. The 24-hour hand with a red tip and the 24-hour markings on the hairline-finished bezel achieve high readability as a GMT watch. While inheriting the wedge-shaped indexes that are an icon of the Alpinist, visibility is pursued by arranging Arabic numerals on a cross line. Details befitting a premium sports watch. The applied indexes pursue a three-dimensional and luxurious feel, and the sapphire crystal has been changed to a curved shape that enhances the classical appearance. Case: DiaShield processing is applied to make it resistant to minor scratches and to maintain a beautiful appearance.
