Very little information is available on it, but apparently it was made by Apple France in 1989. The case is made of steel, the movement is quartz, and the Apple logo is engraved in the dial. The watch is marked with the engraving “Full steel design by Loret & Estevez”, but upon researching Loret & Estevez, very little is found. However, there is significant evidence to suggest that this watch was a real product and that a select group were able to obtain it as early as 1991.
Apparently, it was made by "Magna Carta", a watch company which made a series of watches for several brands, including Apple. The brand's slogan was "Carve your footprint in steel". The watches were distributed exclusively through Apple Authorized Stores and Resellers.
Any information about this watch would be greatly appreciated!
