Seiko Prospex Save The Ocean ‘King Turtle’ SRPF77K1. The watch’s nickname originates from the shape of the case and its similarity to the shell of a turtle. An oversized screw-down crown sits beside the 4 o’clock position and is protected by a crown guard, which increases the functionality of this watch. The ‘King Turtle’ edition is differentiated from the normal ‘Turtle’ with the addition of a unidirectional ceramic bezel with an interesting and practical machining on the bezel edge and an ultra-scratch resistant sapphire glass with magnified date window. The benefit of having a ceramic bezel is that it provides greater durability and scratch resistance than a stainless-steel bezel and will also retain its colour, unlike a painted bezel that may fade over time. The dial of this special edition timepiece represents the view of the ocean as seen by the 5m deep vision of the Manta Ray endangered species. Its colours echo the gradations of sunlight refraction and the patterns symbolise waves seen from under the sea, silhouetted onto the dial are 3 Manta Rays as if seen as a diver would below them looking up to the surface on a dive, a pleasing almost secret element to the dial. The hour makers are covered with Lumibrite which allows the dial to be read in low light. The case of the watch is made from highly durable stainless steel with a fine ‘hairline’ brushed finish on the upper case, while the bottom of the case is beautifully highly polished to a mirror finish, the case is sealed to meet 200m water resistance and is ISO 6425 ‘diver’ rated, able to pass all of the requirements of the most serious of ‘tool’ watch tests. A blue silicone strap with substantial Seiko branded buckle and unbreakable metal keeper provides the ultimate in comfort and hard-wearing practicality for the owner. Renowned for its performance and reliability, Seiko’s inhouse 4R36 automatic movement powers the watch and it is an automatic calibre with manual-winding ability, convenient hacking-seconds function and quick date change facility showing both the day of the week and date of month. With a 41-hour power reserve and 24 jewels, it beats at 21,600vph and has both a good level of anti-shock and anti-magnetic protection for peace of mind. Built to last and backed by Seiko’s trusted global service centre network with a 2 year guarantee, this watch will provide a lifetime of reliable service and pleasure for the owner.
