27AM-400 movement finishing question
I was trying to get a sense of what 3417 patek range. I noticed the little opening on the 27AM-400 movement below the HT in EIGHTEEN in this 3417 copy is quite rough. I wondered what would cause this? Is it a
1. rough initial finish?
2. Ham fisted repair?
3. oxidation/rust etc?
