No hang Tags Then, Gruen And Aegler Movements.

[padi56]

The famous Techni-Quadron some information from Gruen web site ."Doctor's Watches" were so-called because the large seconds dial was handy for timing a patient's pulse. These however were not sold only to doctors. The watch was advertised as a timepiece for technicians and "radio and mechanical engineers"—anyone who needed to measure time in seconds. The 877 movement, manufactured by Aegler in Biel, was also used in the Rolex Prince; this unusual movement gives the watch its distinctive "dual dial" design. Hours and minutes are confined to the upper half of the dial, while the entire lower dial is dedicated to seconds. The Techni-Quadron provided a useful alternative to the tiny seconds hands on most watches from this era, which can be as little as 2mm , and are not practical to use for timing etc.


Aegler made movements for Rolex (which at this time had no own movement manufacturing capability)and has made Rolex movement ever since but now incorporated fully into the Rolex name.Gruen and Rolex were Aegler's biggest customers, and were both large shareholders as well. And the full company name at one time was, Aegler, Societe Anonyme, Fabrique des Montres Rolex & Gruen Guild A. Gruen and Rolex

Gruen sold their Aegler shares in the early 1930s,to Hans of Rolex after they moved all production to the Precision Factory(just another name to appear on a Rolex dial). About this time, Aegler became increasingly tied to Rolex through the sale of stock and shares.And 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.

Thanks for more history. That's a great looking dial. We need more blue steel hands and disconnected seconds.

Thais correct Tudor has resurrected a few past names,Tudor go back a long way into the 1920s then sold mainly Canada and UK.Not till around 1946 they were sold world wide a bit like Rolex they were not sold in the USA till mid 1940s.

That was very cool. I've heard that fable of the LED piece but who knows, might be a legit prototype - It's certainly interesting.

Thanks for posting,
