I am sorry to hear and see those issues...wish people that dont know how to service a speedmaster would just have a conscience and recommend someone else.
The cam screw adjustment for the hour-recorder operating lever is probably adjusted too far, so it now doesnt brake properly- "hour recorder creep" or "drift" is how breitling referred to it (they used the same lemania 1873 for about 20 years).
The hand could be repainted and/or relumed, but a new set is something like $144 retail list (each hand is about $20-ish now USDollars). The marks are from the watchmaker not using plastic when removing the hands or using the wrong tool for the hand removal...
Got a warranty? Otherwise find someplace that has a trained wm and access to omega parts directly. Can be a challenge to find, since most stores misrepresent their watch repair staff as "master watchmakers", but i bet other members can advise.
The issue is that there are some movement parts that can get damaged in disassembly and reassembly during movement service, so a competent wm that knows the movement should do the work.
