Rolex SD/Sub Dial Diameter

[Brightight]

I have a Sea Dweller case in which I've been asked to fit a new dial. However the two SD dials I have are approx 26.51mm diameter and don't fit the case. A Sub dial which fits the case is 29.02mm. I guess these are different rep versions, but which is which as I obviously need to obtain a 29mm dial for this case? Does anyone have any info?

26.5mm sounds like a 1665 dial.

Gen Submariner 16800/16610 is 27.3mm

According to Yuki, a 16660 Sea Dweller dial is 27.3 also

Rep sub dials are typically 28mm+

Noob sub dial just came up 28.08mm on my chinese calipers.

29mm is big.

Maybe a noob SD dial would be in the 28+ range

The blank ETA 28xx dials from Otto Frei that I've been using say they are 28.5mm, though I measure them at 28.3mm. They fit in rep 16610, 16710, 5508, and the 6542 case I bought from you.

Yes 28.5mm would do the trick, the smaller ones leave a gap round the rehaut.
