Same chunky cushion watch case "Mortima-style" - different brands

A very nice large cushion shaped watch case with hidden lugs - seems to have been used by a wide variety of brands in the 70s. Some indicates the width to be 43 mm whereas others says 44 mm. I measure it to have these exact measures:
Width w/o crown: 43,7 mm
Width with crown: 46,5 mm
Length: 43,7 mm
Depth: 15,2 mm (depending on type of crystal - often domed)
Lugs: 19,3 mm

A reasonable theory is that the majority of these cases originates from the same manufacturer. This manufacturer has produced the entire watch (white label) or has just sold the cases - which then has been fitted with movement, dial and hands locally.
Supported by this source the main manufacturer could be Mortima. However normally all products from Mortima has the diver engraved on the back and only some of the watches below has this Mortima signature. If you want to know more about Mortima there is a bunch of info in these posts: History of Cattin & Cie, history of Mortima and large Mortima watches.

Please find below a collection of all the models with this case that I have come across while surfing. The list is sorted alphabetically.

In the end of this article there is more info about the ancestors of this cushion-shaped watch case-type that dates long back. I 1968 Heuer introduced the Camaro which I believe was an important inspiration for the watch case discussed here. It was then combined with elements from the super compressors - especially the internal rotating bezel - and some colorful dials that matches the style of the 1970s. Remove the lugs, which was also a trend at the time, and the "Mortima-style" was born ;-)

The Heuer Camaro introduced in 1968 must have been an inspiration for the "cushion-shaped-hidden-lugs-compressor-style" watch case that was popular in the 1970s. See examples below.

Different dial than thw two Mortima's above. Looks a bit like the Pirofa - see later.

This dial and these hands are common on other Mortima watches but not normally seen on this model. This is probably a frankenwatch.

Very interesting watch. Firstly - it is a french Yema - supposedely these watches branded TYL were made for export. Secondly - this watch seems to be missing the overlay over the bezel with the names of the months. See the watches above how it was supposed to be.

TWO CROWNS - ONE INTERNAL BEZEL - 

AND SOMETIMES WITH AN EXTRA EXTERNAL BEZEL

Note: On closer inspection the following watches with two crowns might actually have a slightly different watch case than the Super Camaro's above.

THE PREDECESSORS

One of the classic watch case styles known as a cushion:

This type of watch shape dates way back. This is a Rolex from from the 1930s. However the width was only 27 mm back then. Source.

The original Panerais had cushion watch cases.

And a Patek Philippe and a Longines from the 1930s.

And to round it off, a modern Panerai Radiomir PAM610 - very delicious:
