Marine Star 96d14. What is the battery type?

Maybe "Bulova" have "Energy save mode" like my "Casio ProTrek"? Both models are quartz movement. When I don't wearing my watch he go sleep after 1 day and wake up when I pick up.

pop the back off the battery should have a number on it or go to the mall, many places there to chang it for you. Not to expensive and shold last a couple years.

I was unable to find the model 96B106 in their range but I did find 98B106. I this is the watch you have, then go to http://www.bulova.com/watches/bulova/marine-star/98b106/ and download the usermanual.

Most of the time you can find the serial and or model number on the first link that is attached to the case of the watch on the back. Often there is a serial number on the back of the case itself. If not in any of these locations you may have to open the case and look on the inside of the case. Be careful with opening case, if you're not comfortable opening the case yourself take it to a reputable jeweler.
If there are no serials on the watch it is probably a knockoff or replica.

Hope this helps.

While I can find "Marine Star" in the list of models, I could not find one with the same refernce number.

There are a number of models so if you go to http://www.bulova.com/brands/bulova/bulova.aspx?brand=bulova#coll_id=30&coll_name=Marine%20Star&gender=1 ", you may be able to find one that looks like yours.

If you click on a watch, details appear and these include operating instructions.

Copy "http://www.bulova.com/brands/bulova/bulova.aspx?brand=bulova#coll_id=30&coll_name=Marine%20Star&gender=1" into your search engine and you should arrive at the Boluva web site page listing Marine Star models.

I couldn't find your particular model but perhaps one of those listed is similar to yours.
