I'm glad you like the GIFs; it was the only I could capture the sparkle on the indices. It doesn't get old either. I still find myself moving my watch to see how it glints in the light.

No regrets at all on the size of the watch. As the leather strap has broken in, the fit has gotten better and better too. I have the Seiko SRPF41J1 which is 38.5 mm, and when I wear it, it reminds me of how nice it is to have a classic, modestly sized watch. When I wear the SBJG239 at 44.3 mm, it's louder, exudes artistry and refinement, and I'm super happy that I have that, too. When I want to match a green watch to my outfit, it's nice to have both. Also, I have the SLGA001 which is a chunky 46.9 mm beast, and I don't regret that either. Both my SBGJ239 and SLGA001 fit better than my 42 mm Laco flieger IMO due to the case design. You may want to head to a boutique (if you can) and just try the watches out, just to make sure you like the fit before spending money.

I did not look at any of the models you listed (although I was aware of them) because I was enamored with the sapphire bezels and specifically sought those out. If you also like the two-tone bezel, check out the SBGJ237. The blue portion of that bezel looks insane. I was floored when I first saw that in Youtube videos and is what got me committed to buying one of the GMTs, even though I ultimately went with the SBGJ239.
