In reply to Brett.

That would really just depend on the specific watch and the type of bezel, as there are many factors to consider here. For example, fixed bezel vs. rotating bezel; alignment of the bezel in relation to dial vs. alignment in relation to the rehaut; type of bezel (single piece, bezel with insert, multi-component); material of bezel and/or bezel insert; etc.

For many Rolex models, particularly those with ceramic bezels, adjusting the orientation of the bezel should really only be done by a highly experienced watchmaker with access to very specific parts and tools. These may not be things that your average jeweler or watch repair shop will not have at their premises. Other watches can have their bezels aligned far more easily by an experienced watchmaker with standard tools simply removing the bezel insert, and realigning it.

Beyond that, there is always the factor of the amount of play that a rotating bezel is naturally going to have due to its design, as this can also influence the perceived effect of alignment. For example, a modern Rolex Submariner will more-or-less have zero play in its rotating bezel, but this is certainly not true for all other brands and watches (including even for older Submariner models).
