The biggest widing issue with the original FOIS was that the crown is skinnier than on original straight lug Models. They remedied this on the New Ed White and also FOIS2. Personally I can't really tell the difference in feel between 321, 1861 and 3861 but do note that the 3313 auto movement used in the Broad Arrow Speedies feels butter smooth in comparison.
Question about new vs old-style end-links…
On the old no. 6/506/516 end-links, two little tabs on the back prevent the end-link from rotating forward. What prevents this on the new style flat-style bracelet link, as I see no tabs in any pictures. Thanks.
Thanks. So, I believe that preemptively answers my question regarding whether this bracelet can be retrofitted to an older Ed White case. No…
