Hello! I'm new here, and I am a big watch enthusiast I have just recently acquired a antique stop watch from my grandmother, who purchased it probably in 1950-1960. The stopwatch box says the company is "Compass" and that it is "Model 400" however, searching the web brings no results of a company called "Compass". On the face of the stopwatch, it says "1 Jewel" and then below that it says "Anti-magnetic". I opened the watch to re-lubricate the 1 jewel, re-adjust the spring and polish the pieces. On the inside of the back pop-off case, it says "Capt&co" with "Swiss" underneath it.
On the movement, it has the same "Compass" logo, along with "Instrument and Optical Co." it also says the jewels again and "unadjusted". There are some numbers: there is two letters "BF" that are circled with an arrow, the arrow pointing counter clockwise. Underneath this "BF" is "795", possibly the movement number. I'll post them if someone needs them. From the look of it, it looks to be a 1/10th second stopwatch, now that I have it working again. I will include some pictures of the stopwatch, and its cardboard box in the post, as well. Its a very beautiful piece of machinery, and I would love to know more about the company who created it, and how much it is worth. Here are the pictures of the box and stopwatch itself, along with a picture of the movement:
