There is NO DOUBT of the Tread 1 being mechanical, but our acceptance is not an argument, but an integral and intellectual debate of it's soul...that it has not a spring within its heart.
I must point out that the possibilities, the potential for knowledge and advancement is great...with the acceptance of greater differentiation in our creation of all things, even in a wristwatch.
As such, maybe it is wise to consider: Kirk's observation of Spock:
"Of my friend, I can only say this: Of all the souls I have encountered in my travels, his was the most... Human."
In accepting the Devon, the Bulova Accutron and Omega's Mecaquartz design...the Devon Tread 1's place in the mechanical watch world:
"Of all the electronic souless timepieces without a balance wheel, or a spring, THIS is the most Mechanical"
