Textured patterns in the finish of internal watch parts have long been a distinctive feature or trademark of different watchmakers. Instead of leaving flat metal surfaces inside the watch just plain and dull looking, they etch interesting patterns into them to enhance the look.

When marketing watches they are mentioned to differentiate brands--especially those using similar movements--but it does not really mean anything useful to the owner.

The 'geneva waves' and 'cotes des armes' are two other patterns you'll tend to see mentioned. In the picture below of the Omega 1120 movement, you can see the 'circular graining' pattern on some of the flat areas (especially near the balance wheel). Also a ridged pattern etched into the winding rotor and some othe rparts is the 'geneva waves.' That's all these fancily named attributes really refer to.
