I need help with my Eve Mon Crois B-303 watch!

Google in help, men.

Hello, A J -

Try a button battery (cell battery) 377, silver oxide, 1.5 v.

Best wishes.

you need to add more info so i can help you

use the little thing that looks like a screw

check with jewelry /watch stores or online search os the strap

Your best bet would be to contract the company for an instruction manual. Their site is in Spanish, but they should be able to help anyway.

When the next minute comes press TR this will reset the seconds to '00' without changing the minute and you will now be accurate to the clock you used by less than a second) I got this info through a long time of just experimenting with the buttons, still working on finding a way of changing the date but for now this should be enough to get you by with the watch. Hope this helps somebody :)

If you don't have a watch repair kit, a small flathead screwdriver or even a butter knife would work. Set the watch face down on a soft material (pillow/towel). Insert the flat tool in the gap between the back and the watch itself. Apply a bit a of pressure the loosen and remove the back. Remove the rubber gasket covering the battery. Then you will want to remove the clip covering the battery (with the flat tool). Once the clip is removed flip it upside down and let the battery fall out
