Default No Rubber seal found in my watch!!

I finally was able to open my Truesmart today after receiving a quality set of screwdrivers ---- But when I got the case opened, there was no rubber seal in there that everybody else has. I removed the battery and added a 16gb micro card. I then put back the battery and closed up the case with the screws. It seemed to fit back just fine and it looks tight, but without that rubber square, I cant let this thing get anywhere near water.
I dread trying to communicate with omate to try and get the rubber seal, but I don't know of any other options.
