Quadron service box

Sat, 26 December 2020 20:33

Two-tone hinged wooden box. The lid is covered in dark red fake leather with an Art-Deco style gold embossed emblem. The main body of the box is covered in brown fake leather material with gold printed borders.
Inside the lid has off-white silk, showing text “Gruen Quadron”, the Gruen crest and “17 Jewels PRECISION”
The insert holding the watch is missing and I also have no idea what it should look like. Please add a picture if anybody has the info. I can then get creative like Jenneke and try to reproduce it Laughing

Watch type : Mens wrist watch
Size : L=13cm W=9cm H =5.5cm
Inventor : Unknown

Gruen Strap 277

1935; Wed, 23 December 2020 03:02

/vgforum/index.php?t=getfile&id=7436&private=0/vgforum/index.php?t=getfile&id=7435&private=0/vgforum/index.php?t=getfile&id=7434&private=0/vgforum/index.php?t=getfile&id=7433&private=0This was my grandfathers watch, a gift from the early 1930s, I think. Works great! I have not been able to find anything out about this watch. Inside the case there are some clues...two sets of stamped numbers...91 and 6048761. The rest of the info on the case looks to be hand engraved. At the top is MK 11-1 n(I think) then the initials JB. Then D22101....44261P....D14422...D17382....D18811...D20636. On the movement is the following...Seven7 Jewels...Unadjusted...F S Conoruma....Hrspg & Bal.....Guild Watch Switzerland.

If anyone could help me out I would appreciate it. Thanks.

18k Gold Alpina-Gruen Techni-Quadron

Fri, 04 December 2020 19:48

Model name: Techni-Quadron
Type: Duo-Dial Wristwatch
Period/date: Circa 1930-1935
Gender: Men's

Case Maker: Weber & Cie
Case Material: 18k Gold
Case Serial: 93133
Case Style no: N/A

Caliber: 877
Movement Maker: Aegler, aka Gruen Guild Factory A
Movement Serial: 1853249

Bracelet: Leather Strap, 14k Original Buckle

Very clean condition, only a few service markings in the case (in an era of less refined oils where service was recommended annually), so presumably worn for a relative short time and put away. The case does not appear to ever have been buffed or polished, with all lines remaining crisp. I am fairly confident that this would best be characterized as green gold. In natural sunlight it looks quite green. And it clearly lacks that hint of orange seen in most yellow gold. But green to yellow gold is a continuum, so it's hard to ever say with certainty. The champagne dial does not show any signs of refinishing, although given that its kiln-fired enamel print that will remain unchanged after refinishing, it's difficult to ever be certain that an early Gruen dial has never been refinished. Likewise, the movement is very clean. And note the wonderful balance guard option not seen on most Gruens. And I say "wonderful" because it allows a ham-fisted owner such as myself the ability to handle the movement with less risk of accidentally damaging the balance. I believe the buckle to be original. It's the correct style of the time. The previous owner represented it as solid 14k gold. There are no markings, but carefully looking at the edges and holes, I do believe that this is solid gold. Given the watch's apparent low mileage and the ancient crumbling strap that was attached when I received it, I don't have a hard time believing that the buckle (and likely strap) were never replaced. Another clue is the buckle's use of a notched rod through a crimped tube rather than a conventional spring bar, i.e. Gruen's patented "Mounting Attachment Means For Wrist Watches and the Like" (click for patent image).

One aspect I find interesting is the case serial number. I have never encountered a Weber serial number that did not follow a X0XXXX (often X00XXX) pattern, usually crisply stamped on the interior of the case. And this applies not only to Gruen-Weber cases, but also Alpina-Gruens with Weber cases that I've come across. For example:
This 93133 not only doesn't follow the usual Weber numerical pattern, it is engraved, and not stamped, on the back of the case. I don't have any explanation (yet), but it is nonetheless a Weber case (more on that below).

Here's a closer shot of the case hallmarks:

The top is the German Sun and Crown mark. However, it does not mean that the watch was actually imported into Germany. Swiss case makers were permitted to use this hallmark themselves rather than having the cases assayed in Germany. So, it only means that the watch was intended for possible export to Germany.

Alpina Gruen needs no explanation.

Next is the head of Helvetia, the Swiss hallmark for 18k gold.

Then there's the "72 18K 0,750" marking. The 18k and 0,750 are self-explanatory, but I had to do some digging to figure out why the number 72 was included. I've run across 14k, 0.585 cases that also had the number 56 stamped on them, so I assumed that there's no way that 72 being similar to, but just below 0.750 and 56 being just below 0.585 could be a coincidence, so it had to be related to fineness. It turns out it's a zolotnik marking. Zolotniks are an Eastern European measure of gold purity originating in Russia. Zolotniks are based on a scale of 96, so 72/96 = 18/24 = 0.750 = 18k. I would assume that the presence of a zolotnik marking as well as the German Sun and Crown hallmark means that they were keeping all options open for exporting to Germany or Eastern Europe.

Then there's the 4/10. It's not something I had seen before, but after some research, I found that it's a reference to a case thickness of 4/10mm. What I was still unclear about is why this mark was included. Forum member DRGM was able to help with that. It turns out that this is a marking championed by Eduard Gübelin, also a customer of Weber & Cie, and while not a Guild member, Gübelin had ties to at least two members (Weber and Favre). DRGM provided me with a translation of this 1935 article from the German language publication Uhrmacherkunst. In it, Gübelin tells a fanciful story of two shops with similar watches, but one is priced significantly higher than the other. His argument is that the customer will have trouble comprehending the differences in movement quality that is responsible for most of the price difference, but if the retailer can demonstrate the quality of the case, that will help to convince the customer of the overall quality of the watch. In his example, the more expensive watch has a 3/10mm thick case. The customer goes back to check out the less expensive watch, sees the thinness of its case, and returns to buy the more expensive watch. Upon appreciating the greater heft of the 3/10mm case, "she had come to the conviction that there must be a difference in the works, even if she did not understand it correctly." So, while I can say that 4/10mm makes for a sturdy, though not an extraordinarily heavy case, evidently it was a thickness worth drawing attention to.

And finally, the number 29 in the Key of Geneva. This is the responsibility mark, or Poinçon de Maître (punch of the master) for Weber & Cie. If the case manufacturer wasn't identified on the case (as it was with most Gruen-Weber precious metal cases), then this mark was required so that any precious metal case could be traced back to its manufacturer. While it's hardly surprising to find an Alpina-Gruen in a Weber case, I'm not sure I would have guessed it absent the responsibilty mark, especially due to the unorthodox serial number. Although in retrospect, I have seen examples of this same case design that were marked Weber, so it does all compute.

In summary, it's a pretty nice watch.

Unknown 18J 8L Caliber (Possibly 857 Extra Precision)

Sat, 28 November 2020 02:53

Here’s a movement I don’t recall seeing before. Listing reports ~17.5mm, which would be 7 3/4 ligne. Lever set. Only seller pics for now.

Anyone familiar with this one? The font & sn suggest Meylan, while the center bridge seems an Agassiz style.

Blue diamond ring

Sat, 31 October 2020 21:47

A Gruen blue river guaranteed diamond ring. Fashioned for the Fifth Avenue Platinum Shops (15W 47th NY). Flower design with 7 small diamonds.

Model: diamond ladies ring with Cathedral Setting
Period: 1927-1932
Material: 14K white gold. River diamonds.
Size: flower H= 9mm, W=9m. Ringsize 6.
Marked: gruen

Other: one of the old terms for the color grade was River. This was for al diamond found in a rivers bed (or alluvial deposits). Before the GIA color grading terminology for diamonds the term “bluewhite” was used to describe the finest highly transparent clear color. In today’s GIA color the River is an E or F (colourless group). Original prices of these rings were $50 or up.


Proud owner Very Happy
