C-Series

The C-Series arc runs through the Bettinardi and Mizuno partnership, with releases on record in 2005 and 2006. The maker's page lists the C-Series as produced during a Mizuno partnership spanning 2005-2008, and bettinardi.com describes it plainly as a Mizuno partnership, putting the line at the front end of that four-year stretch rather than its close.

The 2005 release opens the line under that same banner. The maker's page attributes it to the Mizuno partnership, and bettinardi.com places it within the 2005-2008 window given for the collaboration as a whole.

By 2006, the maker's own account grows more descriptive of the relationship itself. Bettinardi.co.uk lists the partnership behind the 2006 release as Bettinardi Golf having partnered with Mizuno for a great four-year partnership, language that frames the C-Series not as a standalone model but as a product of that multi-year arrangement between the two companies.

Taken together, the two dated releases and the line's own undated entry all point back to the same maker-published period, 2005-2008, for the Mizuno partnership that the C-Series was built inside of. The record holds two releases within that span; what the reader makes of the line's place in that four-year run is their own call to make.
