Seiko 5 Sports Automatic SRPH29K1 100m Men's Watch (Green) Introducing a ‘Flieger’ style into the Seiko 5 Sports collection – a military style originally created for pilots and navigators. The layout of Flieger watches had to be clear and easy to read quickly, as well as being robust and reliable. The new Seiko 5 Sports draws its inspiration from the five decades of Seiko 5 Sports’ success and its design is based on one of Seiko’s most loved sports watches. Every creation in the new collection shares an updated version of this celebrated case and all have the same arrow shaped minute hands, distinctive hour markers and one-way rotating bezel. The movements are all Seiko’s tried and trusted automatic Caliber 4R36, with 24 jewels, optional manual-winding, a 41 hour power reserve and a hacking second hand.
