Cal 6T33 is a compact skeletonized hand-winding movement from Miyota. First appearing in the catalog in 2009, Cal. 6T33 was also known as Cal. 6R33 from 2012 through 2014. It remained in the catalog until 2016 when it was removed.
Cal. 6T33 is similar to Cal. 6T51 but lacks the automatic winding mechanism and calendar components and is skeletonized. A gold plated version, Cal. 6T33 GILT, was also available.
