INGERSOLL watch necklace - Unsure of make/model

[EBUZZ]

Can anyone help me identify this watch/pendant. It was inherited by me from my grandmother and I am unsure as to what it is. It's a watch/necklace with a blue face with the inscription "INGERSOLL" and "Swiss Made". Have tried looking online but to no avail. If anyone knows a make/model or knows where I might be able to find out about it, that would be very helpful.

this brand name has been around since the 1880's, they made what was called dollar watches, easy to look up on the web, most are not expensive but that does not take away sentimental value, the model number might be hard to find as this style could have been made for several decades.......
