Was browsing the modelling sub reddit, and noticed a post about someone having issues with using booleans to cut notches out for a watch bezel in blender, something i seem to be seeing quite a lot of recently (booleans not bezels) anyway after obviously advising him to model it properly/ increase the geometry , I knocked up a quick example in a couple of minutes of one simple , and relativity clean way of doing it.
Thought it may help someone out if they ever come to doing something similar. nothing revolutionary here just quick, clean and easy, i worked out roughly how many segments i need using a disk, split off and modelled one section as seen in the images. To get the little notches i beveled the points with no subdivisions to get a diamond and added some additional cuts and loops before putting it in an array to finish off. nice clean, quad based result with out the use of booleans and/or clean up time etc
