Quadron Import 220

Fri, 01 May 2020 14:53

Model name : Import 220
Type : Quadron Crown Guard
Period/date : 1930-1933
Gender : Gents

Case Maker : Unknown, Swiss made (marked Alpina Gruen)
Case Material : Two-tone, steel with rose gold
Case Serial : 45821
Case Style no :

Caliber : 175
Movement Maker : Marc Favre Co. Biel (Factory "M")
Movement Serial : A451 (?)

Bracelet : After market

Other info :
Although very similar the dial is not identical to the Import 220 model as shown in Mike Barnett's Gruen Watch Catalog (page 107). This catalog also shows a second dial variation called Import 223.

Caliber 175 is a big unknown to me. There is no reference in any of the Gruen documentation available to me of this caliber. Though it is not a "Precision" or "Extra Precision" grade, the level of finishing is to a high standard when comparing to similar calibers like the 325 or 157. Not only the beautiful surface finishing on all sides, but also the one-piece milled yoke and the fact it has an intermediate setting wheel are indications this is a high grade movement.

My feeling is that it could have been produced by Marc Favre Co., Biel. Reason for that is Gruen was also sourcing their 157 and 165/167 Quadron calibers from M. Favre and the escape design is the same or very similar to caliber 157 (but maybe not unique to M. Favre?). Another point is I was able to carry over the detent screw from a 165 which was broken on my 175. I tried detent screws from many different Gruen calibers, but none of them fitted, the detent screw of the 165 was literally identical to the one on the 175. Also the set bridge design of caliber 165 resembles the design of this 175.

EDIT : Information has been updated in line with new info provided by fellow Gruenites. The movement is confirmed as caliber MF175, produced by Marc Favre Co.

Another example; Fri, 01 May 2020 13:18

Model name :Super-G
Type : 24h Jump movement
Period/date :1957-1958
Gender : Gents

Case Maker : Unknown, but most likely Swiss made
Case Material : Steel
Case Serial : 191864
Case Style no : 1108

Caliber : 422RSS
Movement Maker : Gruen
Movement Serial : NA

Bracelet : After market IW SUISSE

Other info :
The dial is most likely a re-dial. Although there are various dial variations of the SUPER-G, the two most common dials are one featuring a centrally positioned gold bordered diamond shape and a version with four 90 degree circular gold lines (both with gold surrounds of the 12, 3, 6 and 9 windows). These are found with and without SUPER-G printed above the 6 position.

Having said that, there is an argument the dial could be factory original. The "factory quality" of the print and dial finish and the fact this is a sunburst dial as opposed to the dials described above, make me belief it could also be factory original. If so, I have yet to find another example to confirm this is true. So until then I will have to assume this is a re-dial.

Show us your favorite timepieces; Sun, 29 March 2020 18:56

Sure has quiet here lately, hope everyone is safe and sound. Show us your favorite timepieces and give some of your personal reasons why.

One of my favs is the VT Huntsman, I love unique lugs and this one fits the bill. I also like the roman numeral design of the era. I have many dials like this in other models. I'm also a fan of patina.
