correct spring bar and link screw sizes
 

I need to replace a few bracelet (oyster) link screws before they get too chewed up. I don't adjust links often, but some of the watches I bought used and had some light wear on the screw slots. So, I found my esslinger screw assortment kit (#81.650 "to fit rolex"). All of my watches have 20mm bracelets (16610, 116610, 14060M (lug holes), 16710B - lug holes, 116622). So what screw to use? And if it's not an esslinger screw, where do you get rolex screws?

And for spring bars, what would be the correct spring bars for the above? I have the esslinger bar kit (#82.002 "to fit rolex") as well. Thx

How about visiting the AD?
Often less expensive as grey market (original Rolex)

the AD route is obviously an option. But since I have the esslinger kits, I'm trying to verify the correct sizes (of the various options in the kits). Take a 93250 oyster bracelet as an example: what is the correct link screw size (thread, dia, length etc). thx

The AD in my place will not sell you any screw pins or spring bars. They insist on taking the watch in and sent it to their service centre. Rolex and service does not go hand in hand.

That rules them out so I am also curious which are the best ones you can buy aftermarket ?
