Case: The four-part case of the RM 039 is incredibly difficult to produce. Machining requires a variety of operations that take close to 11 hours to complete. The five pushers, each of their component pieces, and the crown of the RM 039 require 10 days of machining. The entire casing is then hand-buffed and polished before going through several water resistance and quality control tests.
