ETA

[Kevinw]

I've recently been considering a project using an ETA movement, and it occurred to me how many of these movements are out there in so many applications.

I've had a few with these little gems and have passed on quite a few
Currently I own two





The Rotary is exquisite and the Tramway rather terrible, the casing is rough, the face poor with horrible alignment and the hands lack character.

But inside beats the same heart as many omegas etc....and this is where my wee project comes in, but more of that later.

In the time being gimmie some inspiration, let's see your eta pieces.

[is that my watch]

so how would we define eta ?

suppose the parnis clones are 6497 / 6498 which I use a lot .. but then I am in a middle of a build on a 3602 just waiting to fund the buying of stems and crystal for it ...

Very nice, in the instance of the two I own the Tramway is a 2452 automatic with 25 jewels,
The Rotary is a 2846 if I remember correctly..

this is the one am working on now to go slightly a drift from the eta talk

a 3602 pocket watch dial /hands / movement converted to a wrist watch just got to source a stem and a crystal as I said early
