Blog: Rolex Aegler Xi Trademark

I make additions and corrections to this web site frequently, but because they are buried somewhere on one of the pages the changes are not very noticeable. I decided to create this blog to highlight new material. Here below you will find part of one of the pages that is either completely new or I have recently changed or added to significantly.
The Greek uppercase letter Ξ and its Latinised version written in Roman letters as “Xi”, were registered as trademarks in October 1900 by the company Vve. Jean Aegler. These Aegler trademarks are sometimes seen in the case backs of Rolex branded watches.

Aegler Xi Trademark
Aegler S.A. Trademark Xi and Ξ October 1900
Aegler Trademark Xi Ξ 1913
The letters Xi within an oval, and separately what appears at first glance to be three lines within an oval, were registered as trademarks in October 1900 by the company Vve. Jean Aegler.
The mark that appears to be simply three horizontal lines is actually the Greek uppercase letter Ξ, which is the 14th letter of the Greek alphabet. This is written in Roman letters, and pronounced, as “Xi”.
In the photograph of a trademark stamped in a case dated 1913, the mark is a combination of the two separate marks within an oval.
If it hadn't been for the domination of Aegler by their principal customers Rolex and Gruen, latterly of course Rolex who acquired Aegler in 2004, perhaps the symbol Ξ would be as well known today as is the Ω of another quite well known watch manufacturer.
