Bulova 1950 Darcy
I purchased this watch at a flea market several years ago. It did not run, but I was drawn to the dainty design and the cleanliness of the watch face. I had it refurbished (making the decision not to fix the small chip in the crystal as that added significant cost to the repair) and it ran like a champ for several years. Recently, I noticed that while I could fully wind it in the morning, it would begin to lose time throughout the day, finally ceasing to run by late afternoon. The next day it cannot be fully wound (although after several days of sitting, it will wind as usual) leading me to believe that perhaps the main spring needs to be replaced.
I assumed when I purchased the watch that it dated from the 40's - 50's and have since dated it to 1950 based on the Lo on the back of the watch, however, a search of the adverts of the era do not match this watch exactly. I recognize that the drawings seldom match the actual watch, so I suspect this watch may be a Susan as it is the closest drawing in the adverts that I can find. There are others that appear somewhat similar to my watch, but none (including the Susan) look to have the distinctive double "V" hinge that mine has. I cannot find another like it on the internet outside of a white gold version that is being sold for parts only.
The back is stamped 14k gold (vs rolled or gold filled) and has an expansion bracelet joining the two double rope bracelet parts on each end. The movement is 17 jewels. The inside of the case is marked "Bulova Fifth Avenue New York" and contains "ghost writing" that appears to read L 83H or H83H or 1183H and what looks like 01986H. This lettering is very faint and difficult to make out and I do not know the purpose of it.
