Hey guys, just a quick question regarding Seiko's 5H23 quartz movement popular in late 80's and early 90's Sports 100/150 and dive watches. I understand that this movement is quite similar to Seiko's 5Y23 movement only a slightly higher torque version. Is this the case?

Any help would be appreciated!........
