Hot to open back of bulova millennia motion quartz watch 100m

Chronograph is just a fancy way of saying electric clock. Like in an automobile. Most likely, in your watch, you just need to replace the battery. Take it to Walmart jewelry counter and they can care for it.

I have seen these watches sold on ebay, just make sure it is the genuine made by Bulova.

Watches, well most quartz anyway, are programmed to alert it's wearer to the fact that the battery in the watch is growing weak and needs to be replaced. There are watches that use a 2 second split and then there are those, like my Bucherer quartz that hops at 5 second intervals. Remember, just because you put a "new in the package" battery in your watch does not guarantee that it is new by way of battery power. Some batteries go completely dead while sitting on shelves waiting to be sold. For those of you that don't know, take it from a man of experience, never... ever... ever... store loose change and opened, new or used, coin or watch batteries in the same junk drawer. They will combine chemically to cook off the battery cells like a .22 rounds and pieces can fly pretty fast. Have a great day!

If it is a desk type clock, hold down the 'mode' button, then the up or down button till the time is correct. To set the alarm, hold down the alarm 'on' button til it flashes the time then the 'up' or 'down' button.

It seems as though it needs some attention, i.e. serving might be needed.

If servicing proves to be unsuccessful in improving performance, then it should be sent to their service center (see Boluva.com).

Dude, of course it stops during the night - it's a perpetual motion / kinetic watch. It doesn't have a conventional battery. When you move your arm (while wearing it), the natural motion of your arm will 'automagically' wind the watch. There's nothing wrong with it - these types of watches always have to be re-set in the morning if you don't wear it to bed (or you don't toss and turn in bed).

Batterie model is Panasonic MT920. You can order a Citizen part no: 295-5600 who is a rechargable batterie for watch mouvement Miyota model BR10. That mouvement is use in Bulova motion quartz, Invicta automatic and Citizen eco drive.
