For a 90's seamster 300, how much reduction in diameter should I expect for each link removed? Thanks.

 

I haven't measured, but keep in mind that bracelet does come with a small half-link that provides a very good degree of fine adjustment. I added the half-link to mine to get the fit that's best for my wrist. So I'm pretty sure you'd be able to get the bracelet to the exact diameter you need to wear it in total comfort.

 

In this case, I'm looking at a used watch that comes with two extra links. Wondering how more diameter I could expect out of two extra links.
