Cannon pinion remover

Wed, 03 November 2021 22:48

I dont like cannon pinions when they are stuck.

Gruen did have a tool for it (even patented). Does anyone have one of these?

Two-Diamond Brookline - possible Baguette 519

Sat, 30 October 2021 15:09

Thanks to Barney for help possibly ID'ing this one!

Model name: Unknown, a diamond variant of Baguette 75 (Brookline)
Type: Baguette
Period/date: circa 1933-1934
Gender: Ladies

Case Maker: Gruen
Case Material: --k Gold Filled (no numbers)
Case Serial: 2240302
Case Style no: 134

Caliber: 327
Movement Maker: ?
Movement Serial: 255895

Bracelet: Sturdy Allegheny, marked "patent pending" (possible reference to US2082621, filed 6/1933)


Other info: Baguette 75 shows the same stair-step case decoration, caliber 327, "filled w-y" implying two-tone. Baguette 519 image is missing from book. Its description matches Bag 75, and the 500s models do appear to be slightly dressed-up diamond gold filled variants of others. It is possible this was a Bag 75 that was later "pimped out." IMO, the cleanness of the diamond mounts & borders mean this was made like this at the start. But the fact it isn't two-tone may negate that.

Dial is a match to Bag 72--also a 327 with same style #--so I think it is original/interchangeable.

1923 14k Green Gold Men's Strap Watch

Fri, 01 October 2021 21:08

Model name: Unknown
Type: Strap Watch
Period/date: 1923
Gender: Men's

Case Maker: Unknown Swiss
Case Material: 14k Green Gold
Case Serial: 7979*
Case Style no: N/A

Caliber: 997
Movement Maker: Unknown
Movement Serial: 94508

Bracelet: Leather Strap

Other Information: As far as I can tell from reviewing the caliber 98 thread, we still do not know who manufactured the 98/99/997 movements. This watch has a June of 1926 inscription, but Case helped me pin down a likely date of 1923. Which would also explain why it doesn't appear in the Master Book. It still has its original buckle, marked "Gruen 14k-G B&N Pat. Pending". The case is marked "14C" rather than "14K". I've seen this on other cases, but have yet to identify any rhyme or reason. I would assume it's just nomenclature unique to certain casemakers. I also don't have any leads on who the casemaker might be. Weber cases can usually (but not always) be spotted by their typical X00XXX six-digit numbers. There was another Swiss casemaker working for Gruen with five-digit serial numbers that is also unidentified.
*While at a glance, it looks somewhat like 7379, I'm fairly confident that the second digit is a misstruck 9.


The only known advertisement featuring this model:
This is a 1925 catalog from jeweler S. Kind & Sons of Philadelphia (thanks for Jenneke and Barney for that information). While the catalog references a 15-jewel movement and has a luminous dial, this watch is from the era in which Gruen models were often shown this way, with an illustration of the case style, but then a number of options listed.

And here is a photograph of its original owner, Erret Reed Cooper:
Mr. Cooper was an attorney in LaPorte, Indiana. His great great uncle was none other than James Fennimore Cooper. He was born in 1903, so would have been 23 at the time this watch was given to him. But he didn't receive his Bachelor of Laws degree until 1929. He also held an "honorary degree of Bachelor of Oratory was conferred on him by the British Royal Academy at Christ College, Oxford, England." The article I found doesn't mention when this was received, but maybe a candidate as the occasion for which this watch was gifted.

Here’s a later caliber, found in style number 1046 cases (1960s?). The case & movement are made in France. Imagine my surprise to see it stamped for Alpina!
