Vintage Omega Stop watch

I have searched everywhere i have found an omega stop watch whilst clearing a relatives house, its countdown from 100, its large hand is Dark blue, which u can see clearly if u look side on, the small hand is black, its a wind up watch that works perfectly accurately, it has a smaller face up the top which is numbered 30 down... the back seems to be made of hard plastic rather than any metal, trying to upload a photo from iphone but it says its too large to process 🙁.. does anyone have any info.. or help me about uploading for more info??
