OSTC 5 dimentions

Post by bluebanana »

Hello, I'm trying to get a feel for the size of the OSTC 5. I was going to 3D print a model and see how it would fit on my wrist. The website states 100 mm x 77 mm x 26 mm, but I have been having issues applying the 77 mm x 26 mm dimensions to the side picture shown on the website here: https://heinrichsweikamp.com/media/cata ... _1_web.png

Could someone kindly help to clarify the dimensions please? I'm mainly interested in the A, B, C dimensions as shown in the attached diagram. Thank you.
