Great info !!
👍
Thank you !
The link which you posted has very interesting info about the case maker ID Watch Case Co:
"Information in Roy Ehrhardt's "
Trademarks" book indicates that the
I. D. Watch Case Co., Inc. was located at 121 Varick St. in New York City. He lists the company dates as being from c1930 to 1942." (info user RRwatch).
And the user Mikrolisk indicated that the logo inside the case is a registered mark from 1936, according to "the Kurtis Meyers book "U.S. Horological Trademark Index"
And that movement table from
@bubba48 is very cool too.
I wonder whether Bulova watches were ever cased in non Bulova cases.
