Joined the Speedmaster Club-Few Questions Please

I have been collecting mostly military watches, but I have been drawn into
vintage Speedmasters by all the pictures and posts on OF
So after some reading and studying-
Here is my first venture into vintage Speedmasters-
1968 Transitional with DN90 bezel and spear end chrono hand
Case back appears to have been worn smoothe and is blank (no picture included)
Hands are replaced but I do have the original ones
Came with original case back and dust cover and Omega Speedmaster
clear case back, plus crystal with Omega logo in center
Serial number in the 26,xxx,xxx area
Stepped dial has applied logo
Functions work properly
Most of the original lume on the long indices is gone-just a bit at the center ends still present
Have already scheduled a service for March
Questions:
is the bezel correct? I have read that either DON or DNN can be correct for this
watch
Is the spear end chrono correct? I have read that it is, but not sure about the lume
Replaced hands are superluminova and glow in the dark, but the chrono hand does not glow
Thanks for the help
Now I'll be looking for an affordable 321

Welcome to the club! I love the -68 transitionals.

I'm no expert, but I believe that you have a modern service replacement bezel. The old DN90 bezels have tall TACHYMETRE letters without an accent over the E.

Thanks Davidt3449 + ibis888
I appreciate your help
I thought the bezel looked too new and that it was incorrect,
but I am still enjoying the watch
I now see the attraction of these-a pleasure to wear and awesome look
