Just watch the film Glass Onion on Netflix and has a nice shot of Daniel Craig wearing the 1948 Sub dial watch.

Shows how well a product placement can work in a movie. I'm sure interest for the watch has peaked ever since the movie was released. And this is for a watch that was released 4 years ago. Such a good looking watch. Loved the small seconds version when it was first released but I remember not liking the display caseback that has been obstructed from view with the commemorative designs engraved over it.

Agreed. Why have a display caseback at all if you can't see the movement. It's a bit too thick as well. Lovely dial though.

Pretty much sums up my thoughts on all coaxial Omegas.

Yeah. It's the movement that makes all the modern Omega's thick.

There must be a reason why they made it thicker then. If it's not about the movement, then why? 😕

Same reason why they make watches wider in diameter (40+ mm) when they could definitely be smaller...

Could be a tall handset, thick dial, thick crystal, or even a wide crown tube forcing the midcase to be thicker. Honestly, unless one of us is on Omega's design team, it's impossible to know for sure.

The pre-coax Omega 1120 movement (a modified ETA 2892-A2) was only 3.6mm deep so in fact coax does seem to add thickness, circa 0.5 - 1mm I would suggest. Not huge, but not nothing.

The 1120 is actually 3.9 mm, so the difference between that and a 2500 is 0.2 mm. I personally have not checked to see if this difference is due to the co-axial escapement, or the implementation of the free sprung balance with weights...my gut tells me it's likely more the balance than anything else.

I don’t think the insistence on sapphire casebacks on dive watches helps. Regardless, case thickness (and lack of options getting the coaxial escapement serviced) is the reason I don’t own a modern omega.

Interesting. There seems to be conflicting info on that. I’ve seen an Omega data sheet on the 1120 that suggests 4mm but also this one that states the same 3.6mm as the ETA sheet for the 2892:

I realise I am splitting hairs And further realise you have access to the latest sheet.

That dates from 1995, so this is most likely an error earlier on that was corrected later. This one dates from 2010...



I can tell you for sure (because I've tried it) that you cannot replace a 2892 barrel bridge with an Omega 1120 bridge, because the Omega bridge is thicker, and it will prevent the rotor from making a 360 revolution. So there's no way they were ever the same thickness.

The 1109/110 are 3.6 mm, because they are just rebadged 2892's.

Fair enough. You have said before that the 1120 is not just a superficial 2892 mod and this suggests that is the case.

Perhaps my thinking is clouded by the fact that every time the SMP was upgraded or changed it got thicker, noticeably when the 2500 then 8800 were fitted though I realise as noted above that wasn’t all movement!

Makes sense with regards to the sapphire caseback. That crystal alone is pretty thick and would contribute as a factor as to the thickness of the overall case to accommodate that crystal on the caseback.
