Initially, from the 40's & 50's Von Buren, who owned Squale, manufactured generic cases, and sold them to many manufacturers. Companies like-Altanus Genève, Arlon, Potens Prima, Prima Flic, Jean Perret Geneva, Ocean Diver / Blandford, Deman Watch, Margi, Berio, Eagle Star Genève, La Spirotechnique, Wertex, Carlson Tavernier Geneva and Sinn. The rider was that the watch had to mention Squale on the dial.
They then manufactured specific cases for a number of big players to that manufacturers design. Some of those supplied were Airin, Dodane, Blancpain, Tag Heuer, Doxa, Zeno and Auricoste,
Then Doxa and Auricoste in their Spirotechnique versions and Blancpain in the Bund 3H. These gave Squale much international prestige in the 1970's
In fact at that time Squale was basically a case manufacturer.
Later still, they commenced manufacture of their own range, and it is interesting to note that at least one Squale shares its case with another manufacturer. Their Corrallone series has the Tag 4000 series case as its base. It would be interesting to know why something like that transpired, and who is the patent holder??
All the Doxa cases were from Squale, so I guess some slipped over to Breitling with the Doxa bezel. Maybe the Breitling next version was then a copied case....who would know now?
But how did it transgress to Seiko via Scubapro? ::shakes head::
All records now lost and hidden by the annals of time I guess...it still is really an intriguing story.
