·I'm looking to replace the cracked original crystal on my Omega Seamaster 30, 136.007-63 which has the 285 hand wind movement in a stainless steel 35mm diameter case. I'd like an Omega original, but if thats not available I could use a non-genuine if I knew the precise measurement and where to get one. I hope it would be straightforward to press out the old one and press in the new one with my crystal press. Any guidance would be very gratefully received. Tom in Melbourne Australia
