The a21j movement in the low end Daytonas offered by watheden and idolreplicas have a running "seconds at 6:00" subdial that is synced with the large sweep seconds hand. The other two subdials point to the day of the month and day of week. I could show you a pic of my "really incorrect to the point of being too embarrassed to wear it" Daytona that actually has the l/h subdial labeled Mon - Sun! It actually reflects the mechanism's function but is kinda like getting nekkid, painting yourself neon-orange, and jumping up and down screaming FAKE at the top of your lungs!!!!! Too bad, other than that it's a "looker"!
The 7750 version will have everything running correctly but be a couple hundred more...
