WHAT WE LOVE:

This Citizen Challenge Timer was only intended for the Japanese Domestic Market, which already begins to make it quite rare. The Citizen 8100 calibre was a pretty groundbreaking movement, being one of the first generations of automatic chronograph calibres and stands out amongst these with hand-winding capability and a flyback function.
