My Mother just gave me a wrist watch that was originally owned by my Grandmother. The face of the watch is marked with the word SWIS with no other markings. The case hinges open and on the back inside of the case it is engraved Relion W. Co., Warranted 25 years, 14k gold filled. It is also hand engraved with the letters CA, the date 4/27/42 and the letters LA postioned in such a way that the leg of the L forms the center line of the A. On the back of the movement it is IX 6 JEWELS, ONE 1 ADJUSTMENT and the letters RS and AF with an arrow between them and some sort of symbol underneath. The winding spring appears to be broken. Can anyone tell me about the company and the watch and Approximately how much it would cost to clean and repair?
