Omega Parts Search/Help

Anyone have a line on where I can get a movement cover for my Gen 2 X-33? The one on mine has a crack in it, which causes the alarm to not function when the watch is sealed up. My only local access—the Omega Boutique—insists that they won’t just repair that, rather have to do a full service to the tune of ~$900 (and send the watch back to the motherland for 2 months). I could do it myself if I could get the part. Thanks.
