Makesbelieve
·I recently purchased the often derided ‘birth year’ Speedmaster. During my research I was struggling to make sense of the sometimes conflicting or abstruse relationship between cases, serial numbers, and years.
To help me understand (I'm a visual thinker) I threw together this little chart which I collated from the invaluable info found at Speedmaster 101, Serial number decoder, and Bob's Watches. I thought I'd post it here to help anyone needing a quick and visual reference (click on the image for a larger version). That being said I would still recommend visiting those sites for more accurate and detailed info.
Warning: I have noticed that this info although coming from relatively respectable sources conflicts with other also respectable sources (particularly Ilovemyspeedmaster.com) so take it all with a grain of salt.
I think this visualisation helps show how long certain cases were used, where certain holes in the knowledge base exist, and the relationship between case and year.
I hope it helps someone, Matt
P.S. If you see any mistakes please let me know.
P.P.S. If anyone thinks I've crossed some line here in relation to copyright/fair use etc I'll happily take the post down.
