AUTHENTIC VINTAGE HEBROS INVICIBLE GENTS WRISTWATCH
AUTHENTIC HELBROS EXIBITION TOP/BACK GENTS WRISYWATCH
In 1955 the PUW 60/61 was regarded as the only German movement with chronometer capability. Probably the reason was that the movements were tested by the traditionally responsible Deutsche Hydrographische Institut Hamburg, while Junghans chronometers were tested by the PTB in Braunschweig (PTB = Pysikalisch-Technische Bundesanstalt = German Federal Institute for Phyical and Technical Standards).

Switzerland, an iconic country famous for a people of an impeccable nature, from whom the most precise instruments of time measurement are generated, located in a region that is married to the greatest producer of high fashion the world over, Italy. Within the Italian landscape lies a city, historically known for the intelligence, strength and physical beauty of its inhabitants; CROTON.
The global position of a land possessing people who excelled at precision, strength and beauty led to the natural selection of Croton as the namesake for a timepiece company who sought to establish its very essence on quality, precision and style back in 1878, more than 130 years ago.
As Croton evolved through the years it remained loyal to its origins, always striving to innovate and captivate consumers with its ability to consistently create highly sought after timepieces, ever so precise, at a value all are quick to recognize. By the mid 1900’s Croton had become one of the most sought after and respected names in watches. In 1991 the brand was acquired by Nationwide Time, a family owned business specializing in the manufacture and wholesale of fine timepieces for generations. Nationwide Time had been searching for the right brand to infuse their experience, energy and passion into and they found it in Croton. Nationwide Time President David Mermelstein explains “ our family had been quite successful in the watch business since the 1960’s. We were looking to take our business to the next level and we knew that the time had come to either create or acquire a brand that we could build and work with, for generations to come. When we learned about Croton’s rich and prestigious history coupled with the fact that like our company, Croton had always been family owned, we instinctively knew that Croton was exactly what we had been waiting for.”

1937: Gruen introduces "The Ristside" or "driver's" watches.
In 1938, continuing the success of their VeriThin pocket watches, Gruen also launched a series of Veri-Thin wristwatches. Contemporary Curvex and Veri-Thin movements often are closely related, and can share many parts. By the 1940s, most Gruen wristwatches were either Veri-Thin or Curvex models.
Although Gruen did not manufacture watches for the U.S. military, they offered the public a collection of eight military-style watches, to be used as personal watches.
In 1949, the company introduced their first watches made entirely in the U.S., a line of 21-jewel men's models called the "Gruen 21". The movements are marked "Cincinnati" or "US" instead of the usual "Switzerland."
Fred Gruen retired in 1940 and died in 1945, and his brother George died in 1952. In 1953 the Gruen family sold their interest in the company. The same year, Gruen president Benjamin Katz was forced into retirement after a scandal, and in 1954 the company bought out his shares for $2 million USD.
In 1953, the Gruen Watch Company had its highest sales in its entire history.Gruen, Rolex and Aegler
One of the most deeply-held myths about Gruen is that Gruen and Rolex at one time manufactured movements for each other's watches. Both firms did use some of the same movements—the best known examples are the Gruen Techi-Quadron and its twin, the Rolex Prince. In reality, these movements were manufactured by a third company, Aegler, who was a very close neighbor to the Gruen Precision Factory. They were Aegler's biggest customers, and were both large shareholders as well—the full company name at one time was, Aegler, Societe Anonyme, Fabrique des Montres Rolex & Gruen Guild A. Gruen and Rolex both occasionally showed pictures of the huge Aegler factory in their advertising, making the implication that this was a Gruen- or Rolex-owned facility, although ownership at the time was divided among Gruen, Rolex and Aegler itself. Gruen sold their Aegler shares in the 1930s, after they moved all production to the Precision Factory. After this time, Aegler became increasingly tied to Rolex through the sale of stock. Today, the main Rolex building in Biel is the old Aegler factory, and though it is now owned by Rolex, it is still run by the Aegler family.
