Slide Rule Watches

I have a number of watches with slide rule bezels on them. Thoroughly impractical for me these days with poor eyesight but they intrigue me and I have to have them!!!

Rules that I am searching for

As my main collecting theme is Elektro / Electronic slide rules I try to collect any slide rule of that genre and also slide rules that have hyperbolic scales. 

The following are slide rules that I have been looking for for some years now and I am starting to feel like Captain Ahab searching for  the white whale.


Hemmi 154 ( a two cursor 20inch electrical engineering rule)

Hemmi 301 ( a Control Engineering rule)

Graphoplex 650 and 697 ( French electrical engineering rules)

Reiss 3227 ( an East German rule with hyperbolic scales)

SIC 1580 or Relay 158 ( an electronic slide rule)

IWA 1638 ( The WERN system circular rule)

W&G 465, 454, 443 (Australian slide rules)
