Can someone help me with this case back question

Time247 · Mar 17, 2017

Hello,
Curious to hear from the experts.
I saw a 482xxxx serial speedmaster with a the long S and R - not sure what to make of this back case though?
What year of production would this be from and it correct for the serial?
According to the dating years I found online this should be about 1991 production?
Have a couple of pictures.
Would appreciate any help I can get on this. Thank you for your time.

Pre 98... but before the modern bezel...

Speedmaster101 is not going to help as it's post 145.022-78

I'm sure someone that has a copy of the MWO book can give you a better date range.

This era is hard to nail down and serial numbers have a few years range as they are not sequential.

I have a 3590.50, serial 4825XXXX with an extract from May 31, 1990. Before anyone says anything, yes, they're service hands. Haven't had a chance to put the originals back on.
