Speedmaster Automatic bracelet 1469/813 question

Dear members,
I have a question as regards my speedmaster automatic bracelet 1469/813. I recently bought the watch in very good condition. The bracelet seems fine almost no scratches but there is one thing I am a little unsure about. The endlinks 813 only take 1.5mm spring bars this rather thin ones. The first middle link that conntects the endlinks with the bracelets however has a broader hole so that the thin spring bar does not perfectly fit. Ideally a 1.8mm would fit to increase stiffness. All seems correct however somehow awkward to me. Would you be able to confirm that this combination is correct? Many thanks!
You can see on the attached photo that the bracelet seems to have lots of stretch even if almost unused. You can also see that the first middle link seems not appropriately tight to the end links.

Welcome to OF, first of all.

Not much help with just one image.
My guess is that those are solid end-pieces? Did you try thinner spring-bars such as 1.78 spring bars?

Thanks @Pazzo ! Sorry for not providing better photos I will do so in the evening. I did try 1.78 but the 813 SELs seem to only take 1.5, thicker ones won't fit. It would be great if someone having the exact same bracelet combination could share his/her experience. I really wonder whether such a loose link was intended by omega?
Thanks and have a pleasant day!
Best wishes

@blueteg many thanks for sharing. This looks much better than mine. Would you be able to share a pic from the endlinks from an inside view? Best wishes

You can see on the pic that the spring bars fit perfectly through the end link but are a little loose in the link.

Thanks! Looks much tighter! I am just wondering whether there are any tubes available for the middle link to tighten the hole? Best wishes
