I NEED TO KNOW YEAR OF BULOVA LADIES WRIST WATCH ITS 10 KT AND I HAVE A SERIAL NUMBER z78782. it has bulova ms on back

put make model and any numbers into google.
or put more info on here.
or if you are asking were is the number on the watch you will have to take the back off it and see if there is a number in there.

1. Take the watch off your wrist and turn the watch so that the back of the watch is facing up.

2. Use a watch case opener or a small flathead screwdriver to remove the back of the watch.

3. Carefully take out the old battery and discard it properly.

4. Insert the new battery, making sure the plus and minus signs line up with the corresponding symbols in the watch.

5. Securely close the back of the watch.

6. Put the watch back on your wrist and you're done.

This is just a personal suggestion that I have.
It sounds like you have a vintage Bulova watch and unless there is a watchmaker near you who deals with vintage watches (they are hard to come by!) you will have to rely on the internet but it could be a time consuming project.
What I would do, is go to www.google.com , type in vintage 14 kt Bulova, or 14 kt Bulova, or similar combination, and click on the IMAGE link (second tab at the top of page) and it will bring up every image on the internet of 14 kt bulova watches, etc. Look for the one that looks like yours and then go to the site that has that photo.. It might be helpful
Whatever you do, you have a good watch, Dont get rid of it as the gold is valuable, even if the watch does not work.
Please let me know if this is helpful at all. JKN

You will need to contact Bulova or a local watchmaker. Here is a link for Bulova:

You can get instructions from their web site by going to http://www.bulova.com/brands/bulova/product.aspx?origin=sku&sku=96R19&brand=bulova and cliscking on "instructions".

For most specific info call the Bulova hotline.

if you want a original you need the serial number of the back...try bulovas website or ebay worldwide...from the picture it looks like you will need a original as it looks like its integral to the watch case so prob bulova only try them direct before going to a jewelers or watch repair company...

Serial numbers are generally on the back of the watch.

You may be able to find two or three numbers on the watch.

A case number, a movement number and a serial number.Alternatively you might find a style number (which in your case is 26B44) and a serial number.

I advise you to take your watch to your nearest watch shop and ask them to do it for you.

You can get into difficulty replacing batteries and it is not worth the risk for the small cost saving.

This is particularly true if you watch is sealed as replacing the back can be difficult.

Watch shops use a press to put backs on. Some will snap on using your thumbs, other need the press to apply more force.
