Omega Chronomètre 30T2 SC RG ref. 2410 but with back 2367-3....

Hello everyone,
I am a retired watchmaker from Belgium and I possess (from my father who bought it in a second-hand sate to a client a lot of year ago) an Omega Chronomètre 30T2 SC RG that I have revised and works perfectly.
See pictures inserted.
Its diameter is 35,5 mm.
Its hands and arabic numerals are coated with radium.
The serial number 10190217 engraved on its 16 jewels movement shows its year of manufacture is 1944.
The reference number indicated on its non-screw inox back is 2367-3 but the design of its dial corresponds to the reference 2410(-1 I think, and that has normally a screw back).
So, it seems that it is not its original back.
I have found an 18 mm. replacement black (genuine leather with croco style) strap with Omega logos (on the buckle and on reverse side of the leather) to fix on it and make it prettier.
Its micro-regulator system lacks only a piece (the balance cock that has only an esthetical purpose).
On other Omega forums, I have read that the reference 2410 is considered as ultra-rare.
Can anyone confirm its back is not original and tell me what he thinks about its state in general ?
If you have an idea about its actual value, I would also be grateful to you.
And if you know where I could find / buy the lacking pieces (the balance cock and the original back for the reference 2410), please tell it to me.
Thank you in advance for your time and information / comments.

Seems correct as is....

I thank you very much Mr. Bill Sohne and Mr. Dan S for their comments and data. It is now clear that the back of my watch is original. The remaining doubt is about the dial : why does its design (apparently) correspond to a ref. 2410 ref. and not to a ref. 2367 ? To answer that question, I will try soon to disassemble my watch without damaging it, in order to take and post later pictures of the dial without the bezel and also of the intern part of the case (where a number should be engraved, according to Frano's site). What is clear to me is that I need to find and buy the lacking parts/pieces (262-1339, 262-1340 plus the screw, according to the picture published on the Frano's site) of the micro-regulator (= regulation system) to make it complete. So, if someone knows who could have them and sell them to me (with shipping to Belgium), I would be very pleased.

Yes, you are right; it is not sure that the dial of my watch is wrong. I only understand (when I look at pictures of dials of ref. 2410 watches on the Frano's site: https://squelettewatches.com/chronometres-30mm/ ) that the design of the dial of my watch seems to correspond more to a ref. 2410 than to a ref. 2367.
I sent directly the same pictures posted on this forum to the e-mail of @mac_omega (Erich Lexer) and he asked me to send him:
1) photo of the dial with bezel/crystal removed
2) movement, where he can also see the rim of the case
and I will do so and also publish it on this post.

Thank you again Bill.
Please look at the pictures of the dial itself (front and back, without the bezel) of my watch below.
On the back face of the dial, the following numbers are engraved:
23 531 + upside down P7 (or PZ ?)
23 6086 ZJ
18257 handwritten
The diameter of the dial alone is 3,2 cm
So, what is your conclusion now ?
Do you think it is the original dial of my watch and does it really correspond to the ref. 2367-3 (and not a ref. 2410) as engraved on its back ?

Flueckiger &Cie. Blatt. ZJ. Doppelreferenz. Very likely Radium.

Now, after having received the answer of @mac_omega (Erich Lexer), I know that both the dial and the case back of my watch are original. If anyone of you could tell me where (or to who) to buy the parts 262-1339 (adjuster for regulator), 1340 (adjustment plate) and 2179 (screw for the adjustment plate) in Europe (with shipping to Belgium), in order to complete the regulation system of my watch, please tell me. Thank you in advance.

Omega accredited Watchmaker ?

I am a retired (non Omega accredited) watchmaker from Belgium. I studied watchmaking in Belgium and Switzerland, then I was even a watchmaking teacher, and finally practiced for many years in my own watchmaking-jewellery. The parts can be sold by anyone who has original parts.

Sure, if you find them. For a Wanted to Buy post here you need many, many more postings. Still 200 ? Much easier to ask all your contacts for an Omega accredited Watchmaker to order that for you at the Factory.
