1675 tube and crown ref

Isn't it the smaller tube and crown- 24-503-0 and 24-5030-0? I know the 600 series crowns and tubes weren't used on the GMT. GMTs also were only rated to 50 meters early on, but that may have been the 6542. But it seems even the 1675 was first 50m and then 100m at some point like in the later 60s.
