Zinc air are activated when you take em out of the packet and pull-off the sealing patch . They actually let air into the battery to start the power release reaction . By the same token they will take on dirt and water . Basically they were intended for nice clean and dry conditions such as inside hearing aids . Not the inside of a muddy and steamy old ferret collar!. They often give up the ghost after a few hours and once removed will rarely work ever again anyway .

Also Zinc air batteries might be the same size as the silver ones but they are the wrong voltage anyway . A ZA battery is 1.4 volts wheras the equivalent sized 393 is 1.55volts !

Jewellers are looking at a 500% mark-up on watch batteries but a friendly watch maker might order you a couple of boxes at a better price.

On the other hand there are plenty on the Internet for sale at places like Amazon very cheaply .

393 batteries are seemingly being phased out of the watchmaking industry as they actually last too long and sometimes corrode before the power gives out(when used in watches they can last years). Genuine "Renata" are a good make if you can get them .

Hope this helps .
