Show us your sector dials

The pizza slices are not sectors as i see them on watch dials. The sectors on watch dials cut up the hour ring - in different ways - and have a ( semi) circle ring on the inside of the numerals and there is usualy a minute ring ( rail road track ) on the outside of the minutes.

First patented dial ;



most known in a watch from Patek Philippe, Laurent Ferrier and your CK 859. Here are some more examples also showing a busier version often reffered to as "scientific" dial ;

Jaeger LeCoultre, not mine... 🙁

I think I’m going with @sathomasga

In that figure there are two illustrations of the same dial. On the left, the 12 sectors that I see are colored. On the right, I attempted to color the 2 sectors that I inferred you would see. (I don't think the dial has 2 sectors, but the snippet quoted suggests that you would.) The point of the graphic was to illustrate the different perspectives. Not saying either perspective is wrong or right, just different.


I don't think there's a hard and fast rule, but I think you could make the case for all five of them being sector dials, though some are more obvious than others.


I guess I wouldn't be too picky about where the extended indices are placed. To me, it's enough that the dial makes some attempt to emphasize the indices and (in the spirit of a radius) makes some gesture toward extending them to the dial center. So I wouldn't consider the Railmaster posted earlier to have a sector dial at all; the indices don't really suggest radii since they don't have a sense of continuing towards the dial center; rather they end at their points. Conversely I would count 4 sectors in the Omega pocket watch (emphasized indices at 3, 6, 9, and 12) and either 8 or 12 sectors in the Branch wrist watch (depending on whether or not you wanted to count the implied indices at 3, 6, 9, and 12.) The VC pocket watch, to me, would be the same. (Man, that's a gorgeous pocket watch, too.)

I know this thread is about sector dials but man - the lugs on that zenith! 👍
