1803 vs 11038 Case Size

[vgs]

Hello Vintage part of the forum, I apologize if this has been discussed. I tried using a search with no luck.

I'm a vintage guitar guy but did not venture far into vintage watches. For now haha.

I was looking at DD36mm, and newer ones look a bit different, I guess it's the bezel that makes it so different.

Then I started comparing my 18238 (this could also be called vintage, right?) with 18038 and 1803.

Do they have same case? Is that bezel the same in those references? Am I right when I figured out that each of those brought functionality upgrades into same case?


EDIT: Mod please edit headline, I was being reckless

18038 is about .3 mm thicker case than the 1803 and 18238

18038 and 18238 have same bezel. Not sure about the 1803

So thats almost the same thickness, ok.

Anyone can comment on bezel 1803 vs. two newer references?
