Ah, okay. I've never seen the back of a HP-01 up close before. It looks like you could still use an adjustable case wrench, but it would require a custom set of pins specifically designed for the HP-01. I figured there must be a reason people were willing to pay $79 for a case opener, but the odd design of the HP-01 case back isn't externally obvious. Bulova also made a plastic (nylon/delrin?) case opener with short teeth, which is what I prefer to use on Accutrons since there is no chance of scratching the case back.

I started repairing Accutron watches about 25 years ago, taught by my grandfather who was a watchmaker and Certified Accutron Technician. I stopped about 5 years ago due to eye strain issues.
