Hello everyone, I posted this in the Dating watches thread first but there doesn't seem to be much activity. So I hope this is okay. Because I know absolutely nothing about watches. So I inherited this Omega Automatic Seamaster Big Seahorse from my grandad when he passed away. At least I think it's the Big Seahorse but I'm not sure. I would like to open it to find out the date myself but I'm afraid I'll damage it. I post a link to Imgur with pictures and a short video on how it looks like. I would like to find out as much as possible about it. For example if it's solid gold

Hello everyone, I hope it's okay to post and ask for a dating on a watch. Because I know absolutely nothing about watches. So I inherited this Omega Automatic Seamaster Big Seahorse from my grandad when he passed away. At least I think it's the Big Seahorse but I'm not sure. I would like to open it to find out the date myself but I'm afraid I'll damage it. I post a link to Imgur with pictures and a short video on how it looks like. I would like to find out as much as possible about it. For example if it's solid gold, the date, the exact name and so on. Can someone help
