Like the common NH35a and the NH25a this movement is made by Seiko, is in the S2 class (like the NH35a), has 21,600bph and is exactly like the NH35a in features such as hacking and hand winding and tend to be a lot more reliable than any of the 21j 2813 movements used in reps but the main difference is the size... the NH35a and 25a are used in larger watches and the 05 are used in lady sizes just due to the dimensional differences... you cant just shave down a NH35a and make it fit
