This company used to manufacture watch faces for the old Waltham Watch Factory. It was built in 1897. I'd LOVE to get in there but it was sealed up tight the last time I visited. Part of it doesn't look too stable. It's located in an office park/residential area and neighbors on the street tend to keep an eye on the property. There's a fence up now, but nothing very high.
*STFU*
