ISO Omega-seamaster-14765 SC-1

What an amazing community you have here! Within a few days of posting, this forum was able to help me to identify the exact watch reference number I was looking for based on a single blurry of my grandfather's watch. I regrettably lost this watch a few years ago, before I develop an interest in watches and an appreciation for the value of having a keepsake like this from my family Shame on me, i know I have lost a lot of sleep over the last few months thinking about this)


Now I would like to find an exact version of it for sale. I have put in alerts on EBay, Etsy and Chrono24. What are the other good options to locate a specific watch? Apologize for the incredibly sophomoric question. Very new to the watch community.
