Seiko Prospex Aqua King Sumo GMT Blue Dial Steel Bracelet Mens Watch SFK001J1
Seiko Prospex introduces its first solar watch with a GMT hand, powered by the in-house built new calibre of 5K65.
The watch shape is affectionately named 'Sumo' by Seiko fans because of its size and shape and the 12 o'clock marker - it's a substantially strong looking timepiece.
The Lumibrite colour on the 24-hour hand is high in visibility underwater and the aqua coloured dial produces vibrant accents to the elegantly pressed pattern design. The 200 metre water resistance is paired with a stainless steel case and high power generation efficiency.
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.
Since launching Japan’s first diver’s watch in 1965, Seiko’s innovative watchmaking has changed global dive watch standards.
The Case:
Introducing the Seiko Prospex Aqua King Sumo GMT Blue Dial Steel Bracelet Men's Watch SFK001J1, a timepiece that seamlessly blends style and functionality.
Crafted with a sturdy stainless steel case and bracelet, this watch boasts a robust and durable design that can withstand the toughest of conditions. The 45mm case features a 120-click unidirectional rotating bezel and a scratch-resistant sapphire crystal, ensuring the watch remains protected against scratches and wear and tear. At the 4 o'clock position, the watch features a screw-down crown to ensure proper water resistance.
The Dial:
The blue dial features luminescent hour markers and hands, making it easy to read the time in any lighting condition. The date display is located at the 3 o'clock position, while the GMT hand allows for tracking of a second time zone.
The Bracelet:
This model features an oyster styled engineer bracelet made of stainless steel. The brushed links provide durability while the attention to details is on display with the slight touches of polishing on the outsides of the individual links. The bracelet is secured with a push button deployment clasp.
The Functions:
The watch is powered by the Seiko 5K65 movement, which is the brands first solar GMT movement. With a water resistance of up to 200 meters, the Seiko Prospex Aqua King Sumo GMT is suitable for diving and water sports.
The Seiko Prospex Aqua King Sumo GMT Blue Dial Steel Bracelet Men's Watch SFK001J1 is a perfect addition to any watch enthusiast's collection, with its unique blend of style, durability, and functionality. Whether you're diving or exploring a new city, this watch will be your perfect companion.
