New To Me Speedy

Hello all, I recently bought this Speedmaster ref. 3511.50 which I believe was released in Japan in the '90s with the cal. 1155 movement.
Is there anything I should know regarding this piece, its movement, or synchronicities?
It's en route now and will not be here for a week or so, I'm just wondering what to expect.
Thank you

Welcome in the speedy world!
You will have a little job with black nail polish on the tachymeter...! It works! I did it on the back of mine...馃榿

I've watched a few vids on that and what makes me nervous are the markers that are on the inside of the bezel, against the crystal. I'm sure I'll get it in there and don't know how I'd get it out lol
