I've been doing a lot of searching on the Internet and also watching a lot of videos and there seems to be a good deal of discrepancy about the thickness of this watch's case. Some videos reviews say that it's about 14 1/2 mm and then others say it's around 17mm. Most of the data online that I've seen says it's 17 mm. I'm trying to decide between this watch and a planet ocean Chrono and I'd like to get the thinnest model possible.

 

Yes, there used to be an AT chronograph but not sure if it was a GMT or not. @Wetworks might have had one.

 

The model I had was a straight chronograph, model 2512.30
