Hi everyone, I am new to the forum. I am looking to purchase a 1979 omega speedmaster professional. Pls let me know if anyone is selling one. Thank you.

 

Not the easiest to do. Your going to have to figure out a serial number range and look for 145.022-78 watches in that range.

This will give you what to look for. You want a Dot Next to Ninety bezel and original tritium hands.

Your looking a 44-45million serial number but double check with that site.

DN90 aka DNN aka Dot next to 90. On the bezel Dot should be next to 90 and no accent mark in tachymeter and no serif on the 7 in 70.
