Amusing that rafflesdials sells a vintage No-Date dial that also says on it:
29-2mm-black-dial-marked-rolex-symbol-without-date-window-for-mens-steel-submariner-watch-fit
When I first got the watch, it would stop every few days whilst wearing it. Looking at the Asian movement, it turns out it really was a “DATE” but with a window-less DATE dial. I noticed that the date jumper spring was dislodged and causing the movement to get stuck. I removed it, along with the datewheel and gears and it has been running fine since.
