Apr 1, 2020 · Based on my collection, all my Ekegrens and Koehn-Ekegrens seem to be higher grade watches than Koehns. None of my Koehns have movements similar to any of my Ekegrens or Koehn-Ekegrens. Two of my Koehns have substantially the same movement, ##86,864 and 88,135. Koehn #34,434 has a movement that appears to have been based on a Rannaz …

I have a few 1940s watches that I can run for a week and still be within 30s of where it was set. The hairspring material "Conoruma" is soft and easily damaged. Yours however I think is from the later 1960s; they were using a different hairspring material by this point. Heck most (or all) of their watches at this point were from other ...

This would change the serial numbers and it will not be the grandfathers watch, except for the dial and case. Personally I would source an identical movement and use as a donor. In short I would move parts as needed to get the original watch back in action.

Jan 30, 2022 · Simple mechanics (as the Unitas movement mentioned); I recognize these watches have poorly made cases as well. Ironically the first watch seems to have a more solid crown than the Chronograph itself. Despite that, I would personally go with a $80 White Star Chronograph in good working condition as I've seen before on the market.

Oct 27, 2015 · S/n 194617, an example of a model 4 "15 R" movement. The model 4 was Rockford's first open-face (winds at 12) one. All previous stem-wind 18 size models (2, 3, 5 and 6) wound at 3 o'clock and so were hunting ones (although in the early years Rockford did not actually call them such, there were simply referred to as stem-winders).

Such watches were generally imported for the Henri Stern Watch Agency, the American representative for Patek Philippe. During this time period, most watches intended to be retailed by Cartier were imported by the Stern Agency."

I love the watch and have had no problems at all with it. It is much more of a fashion watch than a classic timepiece, but I think their 1970 series watches are striking.
