34mm × 12.5mm stainless steel three-piece Oyster — case middle, threaded caseback, threaded crown. The case profile reads slimmer than the pre-1950 Bubbleback architecture that the 4925 inherited; the Cal 1030's butterfly rotor is the architectural reason the case middle could come down to ~12.5mm without rotor clearance issues. Lugs are 19mm with drilled spring-bar holes. The bezel is fixed and steel and smooth. | 34mm × 12.5mm stainless steel three-piece Oyster — case middle, threaded caseback, threaded crown.
