Fits all types of RHONDA movements y shape with a single screw or the round shape with double screw fits all Swiss movements including Oakley minute machine and Invicta watches as well as many others. Part number is X/14917 battery. Just screw your purchasing is barely visible with the naked eye you can see it circled in the second picture this is the screw that holds down the battery tie down this also works for the Dual screw version of the Rhonda movement this version will have a screw on each side of the battery tie down you will need two screws obviously these screws are extremely hard to work with my recommendation is have these installed by a professional Jeweler do not attempt to do it yourself you will simply lose the screw and have to start again.
