Omega Speedmaster 125 Anniversary case polishing

Hello, I recently picked up my first Omega, so I joined this great forum! The watch is a Speedmaster 125, and I noticed the front face of the case appears to have been polished to a shiny finish as opposed to the brushed finish on the rest of the watch. If I wanted to get the brushed finish re done, is that something most decent watchmakers can do, or do I need to seek out an Omega specialist? Does anyone have a recommendation for a place that can do it? I only have this one bad photo that I took before I sent it out for a service. Thanks!
