My dad got this watch while working in Libya in the 1980-1990s, I have no other information about it.
Style looks right for the time period you mentioned. I can tell you that your father worked for Mobil Oil Company (now ExxonMobil). That’s their Pegasus logo on the dial. Do you know if the movement is quartz or mechanical? gatorcpa
Pretty easy to find out. Wind the crown. If nothing happens, it's either quartz or broken. In that case, get it to a watchmaker to check out. If it starts running, then it's almost certainly mechanical. Even if mechanical. it probably needs maintenance. gatorcpa
