98b104 crown broken

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.

It is possible a tiny gasket is inside the tread... needing to be REPLACED before proceeding.

First check to see if it is a "left-hand" or "right-hand"
threaded CROWN... Then check that there is no damage to the STEM or the CROWN... You will need at least a 10x (power) jeweler's loupe to see that.

If you have any damage... A watchmaker might be able to dress the treads and save the ORIGINAL PARTS...

Else you are probably looking at replacing both the stem & crown...

When you wind it manually (forward or clockwise) it winds the mainspring. Only need to watch it 5 or 6 times if it's completely stopped you wearing it will do the rest. If you going to get a automatic winder get one that will wind in both directions. It will give a few revolutions clockwise and then we'll go reverse counterclockwise.
Hope this answers your questions thank you.

If you haven't got the user instructions you can get them via the following link:-http://www.bulova.com/watches/bulova/marine-star/98b105/

You should see "download user manual" at the bottom of the page.

Crown(stem) at 10 O'clock has air inlet for temperature, does not move. Crown at 8 O'clock is for setting 3rd time zone next to it. The two buttons on the right of the case, above and below, set 2nd time zone which is at the 6 O'clock position of the large dial. To set #2 push top button till min. hand moves 1 min., then push bottom button to move 1 min each time or hold for rapid movement. Large crown sets date and large dial. Unscrew it (counterclockwise) then pull out to first click, then set date turning crown clockwise, continue to pull out till 3rd click which is where you set the time on the large dial.

You will need to contact Bulova at this link:

1st: make sure the watch is set to "tme" , the botton dail display, press bottom right stem
2nd: pull out the bottom right stem ,
3rd: press the left top stem for increase time . i.e. 2:40 pm to... 2: 45pm
4th, or press the left bottom stem for decrease time: i.e. 2:40pm to .. 2:30 pm
5th: once time is good, then press in the right bottom stem,

Try to advance hands for full circle more (12 hrs more). If this does not work, then you will have to find your nearest watch repair shop, because one of the date change gear wheels is faulty.
Rate me, plz.

Do not open the watch yet, as you do not know how to get the stem out.
Take an eyeglass and examine the crown. You will find the small hub in the centre of the crown. If the centre of this hub is hollow and you can see the thread in it- you will be able to screw it back on stem (all watch crowns are screwed on to stems, never pressed).
If the centre of that hub looks filled with metal, then the stem end is broke and you will need replace stem AND crown (the metal filling the hub is the broken end of stem).
In case if the crown still in tact, let me know by asking questions and I'll guide you through all the process HOW TO.

Rate me, please.

Is the stem broken near the crown? Or do you think there is enough stem to take out of crown? If not you probibly will have to go to a watchmake (NOT a watch repairman) to make you the stem. If there is enough metal to take stem out of the crown you may be able to get someone to solder the stem back together. I do that reguarly with stems that are vintage, and I don't want have the time to remake the whole stem. Let me know. Good Luck!!!!
