Hi all,

I was doing some research to date my Speedmaster, which I recently acquired without any paperwork, and put together this table to help others with their own dating efforts. If you spot any errors, please let me know so I can make adjustments and ensure the information in the post remains accurate. Thanks.

Presumably the title of the watch should be Speedmaster😀

Also, probably 'metal strap' maybe?

My mistake. English is not my first language. Sorry by strap/band 😁
