I have a few Luminox watches and I am now looking at a 1 year old catalog to see what models look the same and might use the same bezels. The good news is there are 3 distinct series of case sizes in the Seal line. Either the original size in 43mm, 44mm in the "color" series and the newer 45mm. I cant see why any PC carbon reinforced plastic 43mm 3000 series bezel wouldnt fit your watch. Perhaps they changed the way the bezel attaches to the case on the newer 3000 series watches. PM me if you need any more info. I would be glad to help you any way I can.|>
