Today we take a look at a recent release by Crystaltimes Horology, the CT707 case. What makes this part special is the exclusion of crown guards. With this design queue, you have the ability to dress up a build, while retaining the heft of a sports watch. It would also make for an awesome vintage inspired build, no crown guard submariner design anyone? The specific mod I build in this video is my “Grand Sumo Diver” which was inspired by the Grand Seiko diver line up. I really like how it came out, hope you guys enjoy as well!
