Vtg 1950s Timex Marlin Demonstrator Watch Mechanical Wind Waterproof Works

This is a vintage 1950s Timex Marlin Demonstrator Watch Mechanical Wind Waterproof It has a half leather band with no buckles, instead the band has a grommet/eyelet at the top, which I believe was used to hang the watch for display as a sample This was found at an estate of a gentleman who was a pharmacist and worked at a small town, independent pharmacy I believe this demonstrator likely was displayed somewhere in the pharmacy as a sample because they sold watches there CONDITION DETAILS: In excellent, pre-owned condition. This working watch looks like it was displayed as a demonstrator and then put away. Sold as is. See pictures for details.
