Leica a Benchmark for Apple Watch Sales?

An article over on Monday Note called "Apple Watch: Hard Questions, Facile Predictions" discusses potential sales numbers for the upcoming Apple Watch (which is set to to drop early next year). Okay, so the Leica connection is a bit tenuous, but we thought the mechanical camera corollary was interesting - to wit:

Unless you were a photojournalist or fashion photographer taking hundreds of pictures a day, these cameras lasted forever. A decade of use would come and go without impact on the quality of your pictures or the solid feel of the product. People treasured their Hasselblads, Leicas (not an SLR), Canons, and more obscure marques such as the Swiss Alpa... These were purely mechanical marvels.
