Seiko 1965 Sportsmatic 5 Ref#. 6619-8060

This watch was manufactured in July 1965.   Movement: Seiko Caliber 6619 automatic mechanism.  It features 21 jewels and operates strictly via automatic winding (it does not support manual hand-winding).   Complications: Day and Date calendar windows. The date can be adjusted using a unique quick-set mechanism by pushing the crown inward.   Case Size: Approximately 36.5mm to 37mm in diameter.Lug Width: 18mm.Crystal: Acrylic / Plexiglass.   Shock  Protection: Features Seiko’s proprietary Diashock system to protect the balance wheel pivot from impacts.Design   Highlights: It features a recessed crown at the 4 o'clock position (hidden to emphasize that manual winding is not needed), faceted gold-tone markers, and a distinct blue inner bezel insert.   Case Emblem: The center features a deeply engraved Seiko Dolphin, which was Seiko's signature hallmark in the mid-1960s to designate a watch with an upgraded Water Proof case design.   The only thing that I could see strange with this watch is it looks like it has an aftermarket blue Bezel that’s it. This watch works like a top. It hasn’t let me down in a few years that I’ve had it.
