Suunto transmitter cover screw type

[cyclade]

Does anyone know the type of screw used to secure the Suunto Wireless Transmitter cover?
One of my screws has a mostly stripped head and I'm contemplating replacing it to avoid future battery change grief. But I can't find any spare part number!

My suggestion would be to contact one of the Suunto service centers such as this one. I would ask if they could send a couple of the screws. They are small enough, they could be put in a small bag and tossed in an envelope for little cost (hopefully free).
