I think this is a Movado watch, case and dial. However, the dial was redone at some point and "Chronometer HF" as incorrectly added. That caption was originally used on Girard Perregaux high-beat (36,000 bps) chronometer movements in the late 1960's.
Hope this helps,

There is a site out there that has a large database without pictures:

There is also a Rolex Dial Project on the same board, but you now need a Tapatalk account to access it.

Like many things in life, this looks like a mixed bag.
The way I read this, the policy is mainly geared towards more modern pieces.
It remains to be seen how this policy is going to apply to older watches. There is no definition of what eBay means by the following, "Vintage watches which...
I also have a Piping Rock and bought this assortment of female springbars from a seller in the Netherlands:
It was not expensive and the 16mm ones fit perfectly. I'm not crazy about the "cup" ended springbars. If they aren't the originals, they tend to slide off at the wrong time. These...
The watch is not recased. It is a Ref. 9086-GA. Oddly enough, the gold-plated ("GA") versions are the hardest to find, although I do not believe it adds to value at all. After all, they are only 20 micron gold-plated. I have a very similar watch.
Here is a Japanese catalog page showing...
That is correct. At the time this watch was produced, Argentina had a heavy tariff on gold watch cases. An easy solution was to import just the movement and have a contractor produce the case under license.This is why "Girard Perregaux" is also engraved on the inside.
This practice is...
All of the examples shown here have a US import code of "BOL" which would correspond with Bernard S. Lippman, the US importer of Lemania (and a few other Swiss brands).

Here is a 1946 ad from Lemania showing a similar, but non-chronometer, chronograph...
The Illinois Watch Co. was taken over by Hamilton in the late 1920's and operated in Springfield, IL until the early 1930's. Hamilton maintained ownership of the "Illinois" brand and occasionally used it on some Hamilton watches in the 1930's and 1940's to keep the name in use.
Landeron never made movements for Omega.
You may be thinking of Lemania. There are many Omega chronographs with Lemania movements. Lemania was a sister company to Omega and Tissot for many years. Today, they are all under the Swatch Group umbrella.

EWC = European Watch Company. Many Cartier watches (mainly those produced by Jaeger-LeCoultre) were engraved with that name, even though neither the movements or cases were produced by Cartier.
As of 1960, the Gruen factory moved from one NYC location to 20 West 47th Street, as per the article below from a US Customs publication:
