Great way to rock a vintage style, very accurate divers watch from Yema. This is a 2020 model which appears to be discontnued on the Yema.com website.

39mm is the head size

32mm is the crystal diameter

48mm lug to lug

19mm lug width tapers to 16mm at clasp

Thickness is 11m or a little less.

Currently sized for my 6 & 1/4 inch wrist. Note in image #2 the extra links which I believe take the max wrist size to 8". Note there is the diver's extension as well. ;-)

I like this watch very much. I just have too many.
