The Gruen 839 movement is probably an inhouse movement from around 1921. It has 18 jewels and is a Gruen Precision Extra grade. It is 6 ligne.

Seller's photos. Will change them when movement arrives.

This movement fascinates me... keep coming back to it, as I’ve never seen one like it.

Just ran across item 371555674969 in the swamp. Siva, a Marc Favre brand. Can’t see works. Could 839 be a Favre ebauche finished at the Precision Factory?

Even better match for the 839: Paul Ditisheim 18J, swamp item 133440866760; close sn to Jenneke’s.

Looking around, the setting mechanism on other Solvils is really close. Here’s one on a 17J: 133385835486

I would say that that siva movement is a caliber 843, not a 839.

The solvils you mentioned are gone, but others look very different on the dial side. Dunno if I would call it a match.

left to the caliber number on my movement there is a character. J?

Yes, I did not see an exact match on the myriad other Solvils, just some similarities.

I don’t have any way to view the 843. Just working with the 1926 parts catalog & later ones. Assuming I’d need 1921 or the 1926 sup B?

RE: J, I also note an obscured letter on your dial side opposite the stem. Could be a J or a U? Also appears to have a few other light numbers near the hour wheel. Fascinating movement!

I still think it’s a Favre base caliber, but the stamp on the main plate is intriguing, to know if there’s a different ebauche supplier.

As far as who supplied to Gruen, stay tuned. The exact sn placement/orientation/font on this P. Ditty is pretty convincing, but I just got another EP grade Gruen caliber that I think is Favre in house—close serial numbers. Let me get plate pics for it

Favre is really turning out to be a major ebauche supplier. That's a unique funny take on the name there Dan, a Sean Combs ebauche. Very Happy

One last detail, with no immediate conclusion: this has an American Art Enamelers dial (like my 610), stamped “1562” & etched “36”. Again, no implication now, but capturing breadcrumbs.

An American Art Enamelers dial + Precision movement could = Katz & Ogush. Being AAE and K&O were on the same avenue, could have made Jenneke's movement one of those platinum cased watches.

BTW- Could that tarnish be of gold substance, how odd?

Must be one that had a gold case (or platinum). On the search for a watch that could fit this movement. This?

I have always wanted to know the casemaker for the gold and platinum watch you are showing here Jenneke. Just going by eye I thought it could be supplied by Werthmüller Frères.

I, too, think it would’ve been in a platinum/diamond or gold case.

Jenneke’s pic is a contender. It could’ve also been a similar model to the diamond/platinum wristlets in 17/18 Guild books, although her model would need to be a few years later. Those are all 7-8 ligne in 1917, and mine above (not Gruen) has a rectangular dial.

Circling back on supplier in this thread, the markings on the 840
[url=https://vintagegruen.org/vgforum/index.php?t=msg&go to=13564&#msg_13564]here[/url] would suggest Favre supplied Gruen & PD. The PD is a different bridge layout, close to the Siva I shared, which doesn’t match Gruen’s (maybe unique for them)

I’ll also note the PD may be a year or 2 earlier than Jenneke’s. He was at ~325k when the 1922 tariff stamps show up.

Jenneke—what could yours have looked like? Be sure to scroll through to pic 12...

Well... that is the kind of watch that is still on my watch list. Diamond are a girl’s best friend.

Definitely a variant of the same movement. Sharp eyes!

I would say... YES. Even that shiny little bit on the escape wheel bridge.

I believe this is the debut ad for this movement, from January 1921...
