Vintage 1940 Hamilton 992E Pocket Watch Elinvar Hairspring
This watch has it all. The sex appeal of the Hamilton 992E Elinvar, a collectors must in any serious railroad collections, alone is reason enough to love this watch. When you put that together with the endless hours I spend finding the best examples on the private market, gives you a watch to be proud of. This Hamilton has a stunning deco style numerals with a red 60 second track and all it's original hands. The dial is near perfect with a faint hairline at 11 o'clock and no other flaws noted. The movement is super clean, and we just serviced it, so it's running great and keeping great time. The original crown has the top crossbar. Not every case has this, actually very few do, so collectors pay more for this. The case is elegant and classic with no personal engravings, this is a very well built case. Please note there is slight brassing around the edge of the reverse of the case and also on the reverse of the bail. On the bail, It is much more defined in the photos in real life. Overall, this is a very nice original example of the Hamilton 922E. Did you notice that the hairspring is blue? Elinvar hairsprings are white metal. From what information I have found, this batch was made during a time when watchmakers were upset that the hairspring was not its traditional blue color and convinced the company that this was causing slow growth. The company decided to treat the hairsprings to make them blue. That is usually done with heat but there are other methods. Just a fun fact, but also makes these rarer because they did not do this in the beginning of the 992E, nor toward the end. I also do not know for a fact that the entire batch were treated or some remained white.
