hello the back plate of the watch either unscrews or pops off. without a good pic of the back of your watch i can't tell. can you flip the watch over and take a real good close-up of it?
Depending on what brand you are seeking, I stock a great many. The Rolex oyster bracelet being very popular and one of my best sellers. I can supply bracelets for any watch. If the factory made it, I can get it. Email me [email protected] Have added some pics of the Rolex bracelets
Ecclissi is the name of the watch brand and has no bearing on the battery maker.
Those batteries are very common and will run between 1-5 dollars for a new replacement.
If you go to http://www.ecclissi.com/customer.html, you will see a contact number for their customer service and they will be able to advise you on a replacement.
