HP-01 Calculator Watch Parts Info


Does anyone know the correct diameter of the o-ring for the back?

I've been trying to contact Geoff, but he must be out of reach.


Out of reach, yep!!

Internet connection died at home for 25 hours. Not after me trying to trouble shoot this end of it by stripping the system down and then checking cables, opening the computer and checking boards and ....

To much rain on the providers box outside causing noise.

The second problem is that I sent three emails to you while in Bejing. Unfortunately, emails from Beijing as I have found out, do not make it through using public wifi.

So here is the answer:

ISO 457 - 35.20 by 34.00 (inner and outer diameter) roughly equivalent to a number 6 in thickness.


Cheers, Geoff
