The 3570.50 might not be vintage by definition but it's a great watch w/a solid movement and one you can wear with a variety of straps to bring more versatile looks. I have enjoyed mine for several years w/o any issues.
Here's mine on an Omega Racing & deployant

I wonder if I might ask, with your 3570.50, do you wind it up daily or every other day and approximately how many winds of the crown when you do?

Best practice is to wind the watch every day. You wind it until you hit a firm stop and you can't wind it anymore. Winding by counting the turns is too imprecise.
