The Miyota caliber 6T33 is a small manual-winding mechanical watch movement with a skeletonized design. It is a time-only 3-hander with no-date (true no-date). This caliber has been in production since at least 2009.

The 6T33 is essentially the ladies size (19.8mm) version of the larger (26mm) Miyota 8N33.

You may also see a similar caliber listed as 6T33G. The G stands for “gilt” or gold plated.

Power Reserve:

With a full wind, the 6T33 has a runtime of about 40 hours give or take. To reach full power reserve, Miyota states that it takes about 35 to 39 winds of the crown (clockwise). This movement can be overwound, so do not continue winding once you feel resistance from the mainspring reaching full capacity.
