Favorite ?.. Well, they all are close to my heart but the black & white E855 (βEbonyβ, because of the center brown/ wood indices within the metal ones), the E872 and likely the blue/blue E875 (Speedbeat) are dear pieces, most with a little special story, how I encountered them. Also there are some more from a bit earlier, the 50/60ies, I enjoy wearing. - Thx again for your kind note βΌοΈ.. Best π
