Miyota 5R32 VS 5R21:
There is a similar caliber 5R21 with the main differences being that the 5R32 discussed on this page is a 3-hand movement VS the 5R21 which is a 2-hand movement (hours and minutes only). This difference also means that the 5R32 to be slightly taller at 2mm VS 1.9mm on the 5R21. Another notable difference is that the driving force needed for the seconds hand causes the 5R32 to have a 2 year battery life compared to the 5R21 with a 4 year expected battery life.
Accuracy:
In official tech documentation, Miyota claims that the Cal. 5R32 has an average accuracy of +/- 20 seconds per month “under normal circumstances”.
Examples of watches with this caliber:
In official documentation, Miyota states that the 5R32 is only recommended for use in lady’s size watches. Despite that, Philip Stein found a loophole and put two full 5R32 calibers inside a “mens” watch model, as seen in the example below.
