Deep Sea Chrono

Submitted by PJ on April 17, 2020 - 4:45pm

Can someone confirm whether the case back on the deep sea chrono is friction fitted or screw down? I suppose I should know but it is not apparent to me and I don't want to do anything until I know for certain. If it is a screw down, is there a specific wrench to use and does someone want to part with one?

Realized I should have uploaded a back side pic.

OK, it is a screw down. I found the polygon cover pins for my LG wrench in the original box it the wrench came in. Swapped out the pins, turned the back, and voila.
