I want to get your view on this.
Recently I posted about the Mido Ocean star and its monocoque/mono-shell case design. I claimed that it was the first of its kind. However today I see bubba48 has posted a Hamilton cld watch. Cld when pronounced phonetically means sealed and it looks like it may well be a contender for the first mono-shell by at least 10 years.
Below are the two designs. First the Mido.
The Hamilton has a well/cup that the movement fits into and it also had a two part stem. My only consideration is that the bezel is separate from the case back so the crystal and bezel are removed to access the movement but the Mido is completely one piece and only the crystal needs to be removed.
I kinda think Hamilton has it but want to get some feedback before I amend my post about the Ocean Star.
