Battery connector

I want to ask about battery connector type for watchX.
For my purpose, the 130mA battery is not enough.
Furthermore, the battery connector type is not a normal one.
Therefore I want to order and replace the new a little bit bigger amount battery.
Please let me know the battery connector type for watchX.
Or can I order it through watchx homepage?

Just updated the Replacement Parts of watchX Please take a look at the latest post. You can make an adaptor to install a bigger battery, it will make it hard to use as a watch though.

Thanks for your comments. BTW, please let me know the exact crimp tool for that connector.

The connectors crimp at the factory so we receive it pre-attached:)
