Watch Description
https://windupwatchshop.com/products/seiko-5-sports-pilot-collection?variant=39639667212354
The Seiko 5 Sports Pilot Collection marks the return of an affordable icon. The original Seiko 5 pilot’s watches are cult classics that brought many people into watch collecting thanks to their mix of timeless design and value. The Seiko 5 Sports Pilot Collection keeps these traits alive, but with a new case and all-new colors.
With a diameter of 39.4mm and a lug-to-lug length of 48.1mm, the SRPHs feature a “just right” case size that most will find comfortable and excellently proportioned on the wrist. The 13.2mm thickness is broken up evenly between the smooth bezel, gently curved mid-case, and a screw-down case back. Protecting the dial is a crystal made from Seiko’s own “Hardlex” -- a proprietary glass that’s resistant to shattering and scratches.
The dial features a “navigator” layout with a prominent outer minute index, and an inner hour index, separated by a ring. On the edge of the dial marks and lume pips provide extra precision, allowing for easy reading at a glance. Large lume-filled sword-style hands are the final touch, maximizing legibility.
Beating away inside the watch at 21,600 bph is Seiko’s 4R36 automatic winding movement. Powered by the movement of your wrist, the rotor will wind up the movement keeping it running for approximately 41 hours between wearings. Within the movement itself, there are 23 jewels keeping things running smoothly. This movement has the ability to be hand-wound, and features hacking seconds for accurate time setting and tracks a day/date display.
