How do I get the back off to replace the battery and watch size battery does it take

The size of the battery required for a Honora watch will depend on the specific model of the watch. However, most Honora watches use a standard watch battery known as a silver oxide battery or button cell battery. The most common size used in watches is the 1.55 volt button cell battery, which is also known as the SR626SW battery or the 377 battery.
To ensure that you purchase the correct battery for your Honora watch, it's always best to refer to the owner's manual or contact Honora's customer service for more information. Additionally, many jewelers or watch repair shops will have the necessary batteries on hand and can assist with battery replacement if needed.

Take your watch to a qualified local watch repair center or jeweler to have the battery replaced. It is very important that a battery is replaced by an experienced professional who can properly seal the back of the watch to prevent damage to the movement.

You are going to need professional help for this one.

Recommendation:
Take your watch to your local watch repair shop they have a watch press that will press the back cover on.

Hope this tip helps.

I believe a local watch repairer will replace the battery for around 5$ that should include the battery, depends on the person.

Generally the battery is replaced by opening the back cover of the watch, in some cases special tools might be required.

the details of the battery read on top the one currently inside it.

The battery has its identification number on it, so if you remove the back of the watch you should be able to read the type without stopping the watch.

Or you could take it to a watch shop, who will have a stock of batteries. Removing and replacing the back of a watch sometimes takes some practice and I advise you to give the job to an expert, especially if it is a water resistant type.
