Very nice Engelton wristwatch with solid stainless steel screw-back case.  Engelton was a New York City Importer who also made watches under the name Normandie. You can find the same dial and movements used in Normandie branded watches on ebay.  The dial is original and in excellent condition, as is the stainless steel case.  The movement was cleaned a few years ago and does run well and now a service is recommended before everyday use.  The 17 jewel manual wind movement is signed Engelton and also has the JXE Swiss import code, which according to the Timeplex.com website indicates the watch was imported by Normandie.  The case measures 31mm diameter and is signed Engelton, Mod Depose, and Brevet which indicates a patent was applied for, perhaps for water resistance.  The case at 12:00 and 6:00 has a fluted design, almost like a bottle cap.  This was very difficult to capture in photographs but you will be able to better appreciate it in person.
