Thank you so much for the assistance - here are additional pictures. Let me know if I can post anything else that might be useful.can you post pictures of the case back and from the side. Looks to be a second generation 300T form the bezel which would put it around late 1968 early 1969.
Thanks!!It's an automatic (self winding). Gently shaking it or moving it a figure 8 pattern will get it going and wearing it will normally keep it going. Pull the crown out one click to set the date and two clicks to set the time. It's interesting because most Sharkhunters black have black dials.
