To take apart a HP-01 - Erik Wahlin - 09-30-2003 Has anybody had any experience taking apart a HP-01 watch? Re: To take apart a HP-01 - David Smith - 10-01-2003 Hello Erik, You guess right. I took one apart many years ago. I seem to remember that there are two of the retaining rings. One I seem to remember is a split ring. I also think one of them is reverse threaded. You need a fine pin spanner to manipulate them... but I used a screwdriver blade.
While on the subject of watches, Harbor Freight Tools sells a watch case opener tool (made in India). It has three removeable bits that can be adjusted in a triagular pattern to match various watch cases. It comes with several types of bits. Sells for $8, $4 on sale. I think you could use just two bits and use it as a pin spanner.
