This Bulova is date coded M2 for 1962. The case back is marked Bulova / stainless steel case/ anti-magnetic/ waterproof/ shock resistant, and has personal initials. It is a manual wind movement that has never been serviced and still keeps excellent time. I do not know the movement number. I believe this model may be known as a Surf King.
Newkid, you should really get it serviced before winding it again. Even though it works and may keep good time it will only do harm. When it does show signs of a problem it may cost more than it's worth to fix. For $50-75 you can have it cleaned, oiled and adjusted (COA).

I second what Darren is saying, here. I am a watchmaker and I see watches all too often that basically self destruct because they have never been serviced, or suddenly start getting wound after many years in a drawer. It took me all of three months to destroy a NOS dive watch I got at a flea market, before I went to watchmaking school. Fortunately I was able to rebuild the watch, but lesson learned. Watches need servicing every 4-7 years, depending on type and use. A proper service is fully disassembling the watch, cleaning it in approved solutions (no ultrasonic, it strips the plates) and lubrication with industry standard lubricants, and regulating after demagnetizing. I see a lot of watches that are merely 'dipped', and then dried out. This is actually worse than no service at all.
