Congrats on your diver.
Any old endlinks most probably will not fit. The early models had very deep cases, and require an end link to match.
Unless you are very lucky, an aftermarket end link won't fit, especially 19mm in 20mm lugs!

This model came in two case thickness, and if yours is early, it'll be the thicker type. These bracelets are hard to come by.

Bezels are hard to source, but pop up every 12 months or so on ebay.
