A Question So Simple...I have no idea what the answer is!

[kip595]

This has been picking at my brain ever since an acquaintance asked me - yes, this is sort of 'asking for a friend', but especially after realizing I had no idea what the answer is, it's gotten stuck in my own head:

What was the final/most recent Steel ONLY ref produced?

The scenario is he does not wear gold for religious reasons (his private business, that's all I got; several gold and tu-tones are in my own collection) - but was heartbroken to realize his relatively new OP had white gold on the indices/hands, so, knowing I tend to go for the older stuff, he asked me the above question. And despite all my reading about the history and what happened when, I can't for the life of me remember or for that matter find the answer!

I want to say it was the Precisions of the 1980s that were the final hurrah of steel case-hands-markers...but some foggy memory that just won't come to the surface keeps telling me that's incorrect.

If only to satisfy my own curiosity at this point, the more knowledgeable vintage guys out there (of which there are many!) are welcome and invited to correct my knowledge!

Thanks guys, as always! :)
