Cartouche 342 (modified)

Thu, 22 April 2021 18:06

Model named: Frank N. Stein
Type: Cartouche
Period/date: case ca 1928
Gender: Female (but big enough to be a man's)

Case Maker: Wadsworth / Gruen
Case Material: 14k reinforced gold filled
Case Serial: 5305616
Case Style no: 153 8

Caliber: 8357B (seventeen jewels)
Movement Maker: Aegler S.A. (Factory A)
Movement Serial: 1920616

Bracelet: aftermarket leather strap

Other info: Movement stamped "GXC" --> imported 1936 or after. I bought this for the 8357 movement. I hesitated to post it, as it appears to be a frankenwatch, but the case style is not present on the forum yet. Cartouche 342 is very similar to 345, but 345 has engraved sides in addition to a bracelet.

I am debating as to keeping it as a wearer. The size is actually quite nice on my wrist, and I like the look with the dial. I note there are a couple of Strap models that used caliber 835, so I figure Fred would probably be okay with it.

The "Extra Precision" calibers - a complete list?

Mon, 05 April 2021 15:10

Howdy all,

I recently looked back at the 1939 parts catalog, and I noticed several other "Extra Precision" calibers I have not seen before. Trying to list them below. Any ones missing from the list?

The EPs in the 300 series are particularly intriguing. Does anyone have any info or setting bits images for the 333? (Edit: I found basic info for that one on a 2014 thread here)

1939 EP caliber list: posted means currently in our caliber database; known means that info (size/shape/jewels) is known about it but not yet in our caliber database.

Gruen Autowind Strap 758

1952/53; Sun, 28 March 2021 19:58

Hello! My mother is visiting my grandmother and she sent me some pictures of one of his watches asking if I wanted it. My plan is to get it restored while keeping it as original as possible. I cannot find much information on the specific dial and was hoping you all may be able to help. Unfortunately I wont have the watch in hand until june to be able to open it and examine the movement. Any information at all would be great ( I realize that a restoration will cost more than the value of the watch most likely, but we wear watches that speak to us, sometime history is woth more than market value) Thanks!

Green Leatherette Men's Service Box

Wed, 24 March 2021 15:10

Period: Guild
Watch type: Men's Wrist Watch
Size: 9 7/8" x 2 1/8" x 1"
Inventor: Unknown
Patents: Unknown
Box maker: Unknown

I'm putting this in the 1930s because my general sense is that before 1930, Gruen was pretty consistent in it's use of that dark brown tiger striped covering material. It seems like 1930 was around the time they started branching out with other colors and shapes.

I have looked long and hard at this box with a loupe in natural light and can find no markings whatsoever. If there ever was any identifying information, it must have been on a long gone sticker.
