I believe this is a 1970 Deep Sea Chronograph with the blue face and bezel. It is marked T Swiss Made T and is stainless steel.
1970 Bulova Deep Sea Chronograph
Here is a good reference to what the original band would have looked like.
Thanks all. I believe I have that band at home. It is one link too tight for me, and I do like the leather strap on it. Not the one I have now in the photos, but I am looking to get a new one. I have already gotten a good warning from a member on this forum to have it cleaned and maintained before any more winds, so I am looking into that. I hope to have this watch in tip top shape shortly.
I really need a new bezel for this dive watch. Any help would be greatly appreciated!!!
