What the research found
These are the research’s judgments, scored against Holden’s priorities, not his own words.
Strengths
- Genuine design story (Interstellar prop faithfully productionized; Eureka Morse-code seconds hand) without novelty-watch cheapness
- 80-hour H-10 with Nivachron in a simple, robust, factory-serviceable package
- Thin 11mm case for a 42mm field watch; no date keeps the dial clean and the movement simpler
- Cathedral handset gives it identity no other Khaki Field carries
Weaknesses
- 100m WR with (unconfirmed) push-in crown is adequate, not sporting
- Crown-position accuracy and hacking behavior not documented by accessible sources
