Another good Amazon watch deal for another highly rated Orient automatic watch.
Mk 2 is the generation, Version 3 refers to the face design.
Note these have a 21mm lug width making it annoying to find suitable straps for them. Most people recommend getting 22mm straps and squeezing them in between the lugs (although 21mm straps do exist).
Get in quick before Amazon price jacks this one like they did to the Mako II earlier today.
Good find OP
