Hello Lmarvin13, welcome to myBulova. You say it's your first Bulova, does that mean there will be more? We call it Bulovitis, you should know that it is incurable and the treatments can be rather expensive.
Your watch is an Oceanographer, a nice looking one at that. I doubt it's seen much 'wrist time' over the years. We always recommend a professional COA (clean, oil & adjust) if you plan to wear these old watches daily. With regular, proper service they can last several lifetimes. I've always liked these calendar bands. I have a couple new old stocks ones laying around here somewhere. You should know that even though the month pictured in Dec 1975 the dates line up to a month in almost any year, that one is the same as February of this year (other than showing a couple extra days of course). As long as you remember what month it is and that the month displayed might have one or two fewer or more days you can still use the old calendar.
