[aapkb]

Hello

Does Rolex Precision movements HAVE to have
the "PRECISION" written on it?

I found this one and im in doubt.

ref 4061

[R.W.T.]

Dial is refinished. Movement is fine. Calibre 710. 10.5 Hunter. 17 jewel. Non Shock Resistant. No adjustments noted.
Post 1940 app.

Shock was kind of a running change showing up as early as 1945. You still see non shock movements up into the late 40s for sure.
