Good day
When my deceased uncle dissolved the household, this Omega Speedmaster treasure came to light.
Unfortunately, my wristwatch knowledge is very limited, which is why I have fought my way through all the different Speedmasters the last few days and tried to acquire a basic knowledge online.
But I would be very grateful if you could check my assumptions and support me with your sound knowledge.

I repair old pocket watches as a hobby and was therefore able to open the Omega without problems to get the type information.

Omega Speedmaster
Production Date: May 1961
No. 17764412 Type: CK2998-4 (Caliber 321)
Bracelet: Type 1171/633

The movement looks original to me, also the bridges are symmetrical, as a 2998 must have.
The Omega logo is correctly "attached" to the dial
But I have problems with the bezel.

Since I am almost sure that this was replaced with a bezel of recent date??
It's a 500 but the 90 point is next to the 90 and I thought it should be at the top of the number?
In addition, "TACHYMETRE" is written without "é".
SWISS MADE are written with a wide "T" and are hardly visible (dial is a bit too low?)
The hour/minute hands also look different, maybe badly replaced??

All in all, I think it's a wonderful old Speedmaster that has unfortunately been badly revised with newer parts like bezel and hands. Or am I totally wrong with my little knowledge?
Please help me to solve this mystery so that I can decide whether this watch is worth revising or in the best case maybe even a sought-after and rare Speedmaster model?

Thank you very much for your help
If you need more detailed photos, just let us know


Best regards
Artos

I’m still a beginner with these too so don’t take my observations as truth. An expert will weigh in soon I reckon, but I think the dial is from a 105.003 (63-66ish?) as the 2998’s didn’t have the T’s next to Swiss Made. I don’t think crown is correct, bezel is definitely newer, bracelet and endlinks are from a newer watch. Movement looks to be in the correct serial range.
Overall a very wearable watch.
