F-91W Micro SD Addon

(These addons are made on-demand. Depending on supply levels, it may take 1-2 weeks before shipping.)

 

This addon allows you to attach a micro SD card socket to the back of your F-91W for carrying around data. You will need a small cross-head screwdriver to install the addon. Also be aware that you will need to bend the 2 contacts up so they still touch the inside of the metal backplate in order to have the alarm beeping sound still present. Check this video out for more info.

Note: The watches/addons ship from the UK.
