aside from what already has been posted, I can add the watch movement is a #109 day date. early to mid 1980's is my guess without seeing the dial code. ( it maybe hidden from view ) . Case appears to be stainless steel which is a good thing. the negaitves are the model 109 like other latter produc tion Timex movements are of less quality and prone to parts wearing much faster than those from the 1960's - and 1970's.
the styling f the watch case is often called a TV dial due to well it looks like a TV of the period. The crystal is perhaps the most difficult of all the parts to source. enjoy the watch and beware of Timex collecting I started with one and have now had thousands!
Great proposition and still practicable for a 20 pounds tweezers or 50 for a screwdrivers mini-set, then things change when you face that a Swiss timegrapher starts at 2,500 but a Chinese one 200 or less, the relation gets a bit better like 4 to 1 in case of bench case opener, crystal press and die set, pressure tester, etc.
