uckle up, this this the first time I have offered this model of Gruen. I have never offered an “European” Gruen Quadron. I am a Gruen Quadron “Fanatic” as reflected in my listings. I probably have 7-10 Gruen Quadron’s. To me they stand for an engineering victory in the mid 1920’s. Remember wrist watches were really an unknown fashion accessory back then, especially for men Gruen had a early collaboration with Hans Wildorf, one of the founders of Rolex. Their factories in Switzerland were across the street from one another. You see, it’s the history particularly early on that intrigues me. Here is your history lesson. The insider case back reads Gruen / Alpina. These two companies in Europe collaborated on many projects including in infamous “Doctors Watch. This is another example of this collaboration What a treasure. If you are a serious collector, especially from the Gruen side, this is a must have. This watch case has fixed wire lugs. Yes, not spring bars. That is why I had to source open ended watch bands. Caliber 175 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. I can confirm that caliber 175 is Marc Favre made, it is even their caliber number. Seems to have been only used in Alpina-Gruen watches, a better quality movement. Alpina Gruen was started in 1929 and the collaboration started to cool down in 1933. So most Alpina-Gruens are dated between 1929 and 1933. But do not forget that for the Alpina-Gruen watches different rules apply. These were intended to be sold in Europe and here European trademarks rules applied. The case maker not necessarily stamped Guildite in the back even also when watches for the US from the same time had the mark already. Completed NOS Crystal Professionally refinished dial Professionally refinished case Comprehensive mechanical service (May of 24) New custom made open ended black watch band Buttero leather Look at the pictures. The watch is in sublime condition. The case was refinished by a European Watch Maker, he did a magnificent job! Look how clean this movement is, no pitting or etching anywhere, a testament to its historical care I have one in my personal collection, it has never been offered for sale. No is your chance. Talk about the epitome of Art Deco. This is the personification of a “Happy” time for the US. This is are and very hard to source. Don’t wait too long. It took me almost a year to source all correct replacement parts This is a conversation starter. This is a jealously watch. Think about this, this is close to 100 years young, look at the condition; it is superb for its age I acquired this timepiece from Germany, the DNA from Gruen of Europe, this is not a stateside import. This was born and sold in Germany or Europe Prior to WWII, Gruen was better known in the USA than Rolex, which at that time was focusing on the British and Commonwealth countries. In 1925, Gruen introduced the men's Quadron. Similar in concept to the women's Cartouche models, these were rectangular watches containing very high-quality 15-j or 17-j tonneau-shaped movements. A larger movement is generally more reliable and accurate, and is generally more rugged, than a smaller one of the same quality, so the Gruen Cartouche and Quadron, with their case-filling, purpose-built movements performed much better than the small, round movements used by most of their competitors at the time. Round movements were still used in the less expensive rectangular Gruen wristwatches...

Buckle up, this this the first time I have offered this model of Gruen. I have never offered an “European” Gruen Quadron. I am a Gruen Quadron “Fanatic” as reflected in my listings. I probably have 7-10 Gruen Quadron’s. To me they stand for an engineering victory in the mid 1920’s. Remember wrist watches were really an unknown fashion accessory back then, especially for men. While this caliber movement was born in 1935 in Europe, it is pure European. I sourced this watch from Germany. I love the interconnected history, it’s not often when you can trace a watch back to its origins. In the US, this is a real treasure to own. Thus is a watch that a serious collector would most likely know its history, to a casual observer, it would not get a mention. Gruen had a early collaboration with Hans Wildorf, one of the founders of Rolex. Their factories in Switzerland were across the street from one another. You see, it’s the history particularly early on that intrigues me. Here is your history lesson. The insider case back reads Gilde. These two companies in Europe collaborated on many projects including in infamous “Doctors Watch. This caliber 485 has the same shape ( barrel) as the Quadron collection. Now compare the picture that shows the caliber 484 with the caliber 157, almost identical. This model is in fact a German Gruen Quadron. The caliber 485 was first introduced in 1935 in Europe. Movement Maker was Gruen/Alpina (Straub) What a treasure. If you are a serious collector, especially from the Gruen side, this is a must have. This watch case has fixed wire lugs. Yes, not spring bars. That is why I had to source open ended watch bands. see the picture. The first set of calibers that you have listed are examples of what I consider the "classic" Quadron movements. These are all 8 3/4"' x 12"' movements, and all have the barrel shape. You should add the later calibers 485, 487, 679, 680, 681 and 682. See below for the well known Quadron caliber movements.
