SD43 - Cyclops Added to Hide Mistake?

Calipers on a dismounted dial will be the only way to know for sure down to a tenth of mm or two.

For hose interested you can download the Rolex dial catalogue here.

IDGuy is suggesting that the cyclops on the SD43 is an afterthought but it's the other way around, Rolex dials with a date window are designed with a cyclops in mind from the start. This is the reason why the Sea-Dweller range without a cyclops have the date window looking oddly inset. Rolex were not going to make a different movement size just for the no-cyclops Sea-Dweller range. With the SD43, things go back to normal as they should be when the date window is meant to be seen though a cyclops.

The day they make a movement with a date disc meant to be seen without a cyclops, they'll put the date window further to the right. But I doubt this will ever happen as the cyclops is part of Rolex's DNA.

Verniers measuring the ID of the Rehaut is the only metric that matters here.
