Hi Joe,

A number of those "space" clocks were sold on eBay in 2003. Here are photos:

For your Hamilton chronometer performance question, see section "10^-7" of:

p.s. Note that time-nuts is not a "clock & watch" forum, so if you have 
additional mechanical clock comments I can point you to web sites or 
forums that focus on that topic. For more info on time-nuts see the home
