Omega Speedmaster 321 hour minute hands differences

Hi guys,
I have a lovely Speed 105.003-65 but tritium is completely dark on minute and hour hands, and somewhere is missing. On the contrary chrono hand is still very nice, a little warmer than tritium on the dial.
I'd like to find two vintage hands with original tritium (I don't want to relume).
Are there micro or macro differences (measures or shape) among hour and minute hands in 321 references (from 105.003 till 145.012)?
I try to find this info into the web but no answers.
Thank you for help.

Post a pic. Maybe your search is in vain. As to your question, the answer is ‘yes’ (same hands could also come from different suppliers) but you have to dig really hard to find all info.

This is “the problem”

Well, not sure if I would call that a problem at all. To my eye those hands look legit, correct, and great in terms of patination (a lot of original vintage pieces have slightly different color hands) with the watch as a whole. Plus, good luck finding a new-vintage matching set like that! But if you do : dibs on that hand-set 😀 Its well known in watch manufacturing that hands/dials etc were/are made by different contractors ... which means that even the lume in the hands are from a different mix (have a few modern pieces where its like that) so that is totally 'normal'. Also, on the vintage tritium ones, depending on the life the watch led, they could patinate quite differently. IMHO that difference in color is quite common on unprepared pieces. More recent cal 321 service tritium drop-end chrono hands (e.g. 90's) might have a slightly different shape (only really visible to the super-pedants in us) and even length, which some find ok, but to 'purists' not. Usually what is contrasting and hits the eye after installation, is the brightness of the white paint (and not necessarily the matchy-matchy lume) : often that screams 'new hands'. If that were my watch I would be quite happy and leave it alone. But its yours. If you do switch hands, give special instruction to be careful with those, as they will have some value.

Edit : ps : were the hour/minute hand ever 'stabilized'?

No they have never been.
Can I please know what you mean for "stabilized"?

Agree with Eugene. Common color combination with the chrono hand being more orange than the rest of the hand set.
I have one too!

Wow!! What a DON!
